Remote cardiology clinic visits during COVID-19 were used more often by certain traditionally underserved patient groups, but were also associated with less frequent testing and prescribing, new research shows.

“The COVID-19 pandemic has led to an unprecedented shift in ambulatory cardiovascular care from in-person to remote visits,” lead author Neal Yuan, MD, a cardiology fellow at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

Their findings were published online April 5 in JAMA Network Open.

“We wanted to explore whether the transition to remote visits was associated with disparities in how patients accessed care, and also how this transition affected diagnostic test ordering and medication prescribing,” Dr. Yuan said.

The researchers used electronic health records data for all ambulatory cardiology visits at an urban, multisite health system in Los Angeles County during two periods: April 1 to Dec. 31, 2019, the pre-COVID era; and April 1 to Dec. 31, 2020, the COVID era.

The investigators compared patient characteristics and frequencies of medication ordering and cardiology-specific testing across four visit types: pre-COVID in person, used as reference; COVID-era in person; COVID-era video; and COVID-era telephone.

The study looked at 176,781 ambulatory cardiology visits. Of these visits, 87,182 were conducted in person in the pre-COVID period; 74,498 were conducted in person in the COVID era; 4,720 were COVID-era video visits; and 10,381 were COVID-era telephone visits.

In the study cohort, 79,572 patients (45.0%) were female, 127,080 patients (71.9%) were non-Hispanic White, and the mean age was 68.1 years (standard deviation, 17.0).

Patients accessing COVID-era remote visits were more likely to be Asian, Black, or Hispanic, to have private insurance, and to have cardiovascular comorbidities, such as hypertension and heart failure.

Also, patients whose visits were conducted by video were significantly younger than patients whose visits were conducted in person or by telephone (P < .001).

In addition, the study found that clinicians ordered fewer diagnostic tests, such as electrocardiograms and echocardiograms, and were less likely to order any medication, in the pre-COVID era than during the COVID era.

“If you don’t have a patient in front of you, it’s much more difficult to get a physical exam or obtain reliable vital signs,” said Dr. Yuan. Communication can sometimes be difficult, often because of technical issues, like a bad connection. “You might be more reticent to get testing or to prescribe medications if you don’t feel confident knowing what the patient’s vital signs are.”

In addition, he added, “a lot of medications used in the cardiology setting require monitoring patients’ kidney function and electrolytes, and if you can’t do that reliably, you might be more cautious about prescribing those types of medications.”
 

An eye-opening study

Cardiologist Nieca Goldberg, MD, medical director of the New York University Langone womens’ heart program and spokesperson for the American Heart Association, recounted her experience with telemedicine at the height of the pandemic in New York, when everything, including medical outpatient offices, had to close.

“We were experienced with telemedicine because we had started a virtual urgent care program well ahead of the pandemic,” she said. “We started using that to screen people with potential COVID symptoms so that they wouldn’t have to come into the hospital, the medical center, or to the offices and expose people. We learned that it was great to have the telemedicine option from the infectious disease standpoint, and I did visits like that for my own patient population.”

An equally if not more important finding from the study is the fact that telemedicine increased access to care among traditionally underserved demographics, she said.

“This is eye-opening, that you can actually improve access to care by doing telemedicine visits. It was really important to see that telemedicine has added benefit to the way we can see people in the health care system.”

Telemedicine visits had a positive impact at a time when people were isolated at home, Dr. Goldberg said.

“It was a way for them to connect with their doctor and in some ways it was more personal,” she added. “I actually got to meet some of my patients’ family members. It was like making a remote house call.”

Stable cardiology patients can take their blood pressure at home, weigh themselves, and take their own pulse to give an excellent set of vital signs that will indicate how they are doing, said Dr. Goldberg.

“During a remote visit, we can talk to the patient and notice whether or not they are short of breath or coughing, but we can’t listen to their heart or do an EKG or any of the traditional cardiac testing. Still, for someone who is not having symptoms and is able to reliably monitor their blood pressure and weight, a remote visit is sufficient to give you a good sense of how that patient is doing,” she said. “We can talk to them about their medications, any potential side effects, and we can use their blood pressure information to adjust their medications.”

Many patients are becoming more savvy about using tech gadgets and devices to monitor their health.

“Some of my patients were using Apple watches and the Kardia app to address their heart rate. Many had purchased inexpensive pulse oximeters to check their oxygen during the pandemic, and that also reads the pulse,” Dr. Goldberg said.

In-person visits were reserved for symptomatic cardiac patients, she explained.

“Initially during the pandemic, we did mostly telemedicine visits and we organized the office so that each cardiologist would come in 1 day a week to take care of symptomatic cardiac patients. In that way, we were able to socially distance – they provided us with [personal protective equipment]; at NYU there was no problem with that – and nobody waited in the waiting room. To this day, office issues are more efficient and people are not waiting in the waiting room,” she added. “Telemedicine improves access to health care in populations where such access is limited.”

Dr. Yuan’s research is supported by a grant from the National Institutes of Health. Dr. Goldberg reported no relevant financial relationships.

THE CASE

A 23-year-old woman with past medical history of bipolar II disorder and a REM-specific seizure disorder that resolved at age 9 presented after a syncopal episode. The patient reported an initial sensation of lightheadedness while at work, which was followed by a syncopal episode with brief (1-2 min) loss of consciousness and a minor head injury.

She denied other prodromal symptoms including chest pain, shortness of breath, ­palpitations, and nausea. She also did not experience convulsions, urinary/bowel incontinence, or confusion upon regaining consciousness.

She denied previous syncopal episodes. However, she reported that, 2 weeks prior, there had been an event similar to that of her presenting complaint. During that episode, she experienced lightheadedness and a fall without loss of consciousness.

The patient had been prescribed a regimen of sertraline 100 mg/d and aripiprazole 10 mg/d to maintain mood stability. She had self-discontinued these medications about 8 months prior to presentation. A recent return of her depressive features had prompted a restart of this regimen 1 week before her first fall, without an initial taper upward.

While in the emergency department, she became bradycardic (heart rate, 38 beats/min) and hypotensive (blood pressure, 70/40 mm Hg). She subsequently became increasingly somnolent and had 1 episode of emesis. An electrocardiogram (EKG) revealed sinus bradycardia without other acute abnormalities (FIGURE).

Blood work including a basic metabolic panel, complete blood count, and cardiac enzymes were all within normal limits. Computed tomography of the head revealed no intracranial pathology. Her vitals were initially unresponsive to a fluid bolus but improved and stabilized after administration of intravenous atropine 0.5 mg.

Aripiprazole was held and sertraline was decreased to 75 mg on hospital Day 1, with close monitoring of her mood. Cardiology was consulted and followed the patient ­during her stay. The patient was monitored on telemetry for 3 days, exhibiting only sinus ­bradycardia with a stable heart rate of 45-55 beats/min. Systolic blood pressures were ­stable within 120 to 130 mm Hg. Transthoracic echocardiogram performed on hospital Day 2 was unremarkable, revealing a normal left ventricular ejection fraction of 65% and no wall motion abnormalities. She had no recurrence of the syncope or emesis.

Continue to: THE DIAGNOSIS

Given her benign cardiac work-up and symptom onset coinciding with the abrupt resumption of high doses of aripiprazole after an 8-month abstinence, the patient’s presentation was attributed to a rather uncommon adverse drug reaction to aripiprazole. This has only been described in a few case reports.

DISCUSSION

Aripiprazole (Abilify) is an atypical antipsychotic frequently used in the treatment of psychiatric conditions, including bipolar disorder and schizophrenia. While the specific therapeutic mechanism is unknown, it is believed that drug efficacy is related to partial agonism at dopamine D₂, serotonin 5-HT_1A, and serotonin 5-HT_2A.¹ As aripiprazole works on a variety of receptors involved in other physiologic processes, clinical adverse effects have been reported, most of which are associated with the adrenergic alpha₁ receptors.¹ These include cognitive impairment and seizures. Cardiovascular adverse effects of aripiprazole include orthostatic hypotension, cardiac arrhythmia, prolonged QT interval, and syncope.^1-5

Family physicians should inquire about aripiprazole use in patients who present with cardiac symptoms.

Selective serotonin reuptake inhibitors (SSRIs) such as sertraline (Zoloft) have also been shown to cause cardiac arrhythmia and syncope.⁶ Although sertraline may have contributed to the patient’s cardiac symptoms, it is more likely that the aripiprazole was the direct cause, as she remained asymptomatic while on a therapeutic dose of sertraline. Furthermore, aripiprazole is primarily metabolized though hepatic CYP2D6, which sertraline has been shown to inhibit.^1,7 Therefore, the concomitant use of sertraline with no initial taper of either medication likely led to an increased effective dose of aripiprazole in our patient and subsequently to her presentation.

Few prior cases have identified aripiprazole as a cause of antipsychotic-associated bradycardic response.⁸ Based on the Adverse Drug Reaction Probability Scale, often referred to as the Naranjo Scale, we believe this to be a probable adverse response in our patient.⁹ Bradycardia followed a reasonable temporal sequence after aripiprazole use with a response previously described in the literature. Symptoms also improved after discontinuation of the drug and other etiologies of the bradycardia were ruled out.

Our patient was discharged with a 30-day cardiac event monitor and a scheduled appointment with Cardiology.

Continue to: THE TAKEAWAY

As this case suggests, there may be an association between aripiprazole and symptomatic bradycardia. Therefore, family physicians should inquire about aripiprazole use in patients who present with cardiac symptoms and consider tapering this medication if other causes cannot be identified. Additionally, given the potential cardiac adverse effects of atypical antipsychotics, physicians may consider ordering baseline and follow-up EKGs to monitor for arrhythmias in patients prescribed aripiprazole. This may be especially prudent when an atypical antipsychotic is combined with an SSRI, as potential cardiac adverse effects may occur more frequently.

A new antiplatelet drug with a completely novel mechanism of action may hold the promise of delivering the holy grail – reducing cardiac events without increasing bleeding. That is the hope behind the new class of drugs directed against the platelet collagen glycoprotein VI (GPVI) receptor.

A phase 2 trial with the first agent in this class, known as revacept (advanceCOR), showed no increase in bleeding with the product when added to standard dual-antiplatelet therapy for patients with stable ischemic heart disease undergoing elective percutaneous coronary intervention (PCI), despite the drug’s being used at a dose that has been shown to increase platelet inhibition.

Unfortunately, there was no reduction in the primary clinical efficacy endpoint, a myocardial injury surrogate, but the authors pointed out that the overall event rate was low, and they were hopeful that future trials in a higher-risk population will show efficacy.

The ISAR PLASTER study was published online on March 31 in JAMA Cardiology.

“This new drug is targeting the collagen in the extracellular matrix of atherosclerotic plaque rather than the platelets themselves. So, in theory, this agent should not cause an increase in bleeding,” study author Steffen Massberg, DrMed, said in an interview.

Dr. Massberg explained that revacept targets the binding site for platelets on collagen that is exposed on rupture of atherosclerotic plaques and is a major trigger of platelet activation.

“In contrast to aspirin and P2Y12 inhibitors, which target all platelets, revacept only binds to sites where there is ruptured plaque. But the platelets themselves otherwise have normal function, so regular coagulation processes should be unaffected,” he commented.

“While collagen also has a role in the coagulation process, it is more involved in atherosclerotic plaque rupture, and in animal studies, revacept was effective in preventing clot formation in large arteries but only had a small effect on bleeding,” Dr. Massberg added.

In the JAMA Cardiology article, the authors further elaborated that, when collagen is exposed during atherosclerotic plaque rupture, it binds platelet GPVI, the major platelet collagen receptor.

“Glycoprotein VI in turn mediates local platelet recruitment, activation, and aggregation. Glycoprotein VI is an attractive antiplatelet target because GPVI-mediated platelet response plays a central role during myocardial infarction and stroke but is less relevant in physiological hemostasis,” they wrote.

The researchers describe revacept as a dimeric, soluble fusion protein composed of the extracellular domain of the GPVI receptor and the human Fc-fragment. It competes with endogenous platelet GPVI for binding to exposed collagen fibers and inhibits collagen-mediated platelet adhesion and aggregation selectively at the site of plaque rupture.

In addition, revacept blocks binding of von Willebrand factor to collagen and inhibits von Willebrand factor–mediated platelet activation, they reported.

“As a lesion-directed drug, revacept does not interfere with the function of circulating platelets beyond the atherosclerotic lesion,” the authors said.

In animal studies and a phase 1 clinical trial, the drug was shown to inhibit atherothrombosis but to have little effect on systemic hemostasis or bleeding.

The current ISAR-PLASTER trial is the first study of the use of the agent for patients with coronary heart disease.

For the study, 334 patients with stable ischemic heart disease undergoing elective PCI were randomly assigned to receive a single intravenous infusion of revacept 160 mg, revacept 80 mg, or placebo prior to the start of PCI in addition to standard antithrombotic therapy.

The safety endpoint was bleeding of type 2-5, per Bleeding Academic Research Consortium (BARC) criteria, at 30 days.

Results showed no significant differences in the primary efficacy endpoint (the composite of death or myocardial injury, defined as an increase in high-sensitivity cardiac troponin T [hsTnT] to at least five times the upper limit of normal within 48 hours from randomization) between the revacept and placebo groups. The primary efficacy endpoint occurred in 24.4% of the revacept 160-mg group, 25.0% of the revacept 80-mg group, and 23.3% of the placebo group.

The high dose of revacept was associated with a small but significant reduction of high-concentration collagen-induced platelet aggregation, but adenosine 5-diphosphate–induced aggregation was not affected.

Revacept did not increase bleeding. Bleeding of BARC type 2 or higher at 30 days occurred in 5.0% of the 160-mg group, 5.9% of the 80-mg group, and 8.6% of the placebo group.

Dr. Massberg pointed out that one possible explanation for the lack of difference in the efficacy outcome was that the patients enrolled in the study were at low risk.

“The rate of major adverse cardiovascular events was very low (2.5% at 30 days), and this was a low-risk population undergoing elective PCI,” he commented.

The authors also pointed out that the five-times increase in hsTnT endpoint used in the current study has little prognostic impact.

In addition, Dr. Massberg noted that, in the stable situation, myocardial injury is mostly triggered by cholesterol embolism during PCI and side-branch occlusion due to distal plaque embolization, problems that are unlikely to respond to inhibition of GPVI-collagen interaction by revacept.

He suggested that better results may be achieved in patients with acute coronary syndrome (ACS). “In ACS patients, the myocardial injury is caused by ongoing thrombotic cascades, where the collagen-platelet interaction plays a much larger role, so in theory, this drug should show a greater effect in an ACS population.”

The researchers are now planning a larger phase 3 study in that group.

“I am still optimistic. I still believe it could work,” Dr. Massberg said. “The major aim for this study was safety and dosing. There was no difference in bleeding, so safety was supported,” he added.

The ISAR-PLASTER study was funded by the German Center for Cardiovascular Research, Deutsches Herzzentrum Munchen, the Federal Ministry of Education and Research, and advanceCOR (the manufacturer of revacept). One of the coauthors of the study is a cofounder of advanceCor.

In 2015-2016, almost 40% of adults and 18.5% of children ages 2 to 19 years in the United States met the definition for obesity—a chronic, relapsing, multifactorial, neurobehavioral disease that results in adverse metabolic, biomechanical, and psychosocial health consequences.^1,2

Tremendous resources have been invested in research, policy development, and public education to try to prevent obesity and its related complications. Despite this, the obesity epidemic has worsened. Here, we explore how to evaluate and treat obese patients in a primary care setting based on the evidence and our experience seeing patients specifically for weight management in a family medicine residency teaching clinic. Pharmacotherapy and surgery, while often helpful, are outside the scope of this article.

It begins withan obesity-friendly office

Patients may have reservations about health care interactions specific to obesity, so it is important to invite them into a setting that facilitates trust and encourages collaboration. Actively engage patients with unhealthy weight by creating an environment where they feel comfortable. Offer wide chairs without armrests, which will easily accommodate patients of all sizes, and ensure that scales have a weight capacity > 400 lb. Communicate a message to patients, via waiting room materials and videos, that focuses on health rather than on weight or body mass index (BMI).

Understand the patient’s goals and challenges

Most (although not all) family physicians will see obese patients in the context of a visit for diabetes, hypertension, or another condition. However, we feel that having visits specifically to address weight in the initial stages of weight management is helpful. The focus of an initial visit should be getting to know how obesity has affected the patient and what his or her motive is in attempting to lose weight. Explore previous attempts at weight loss and establish what the patient’s highest weight has been, as this will impact weight-loss goals. For example, if a patient has weighed > 300 lb all her adult life, it will be extremely difficult to maintain a weight loss of 150 lb.

What else to ask about. Discuss stressors that may be causing increased food intake or poor food choices, including hunger, anger, loneliness, and sleep difficulties. Multidisciplinary care including a psychologist can aid in addressing these issues. Ask patients if they keep a food diary (and if not, recommend that they start), as food diaries are often helpful in elucidating eating and drinking patterns. Determine a patient’s current and past levels of physical activity, as this will guide the fitness goals you develop for him or her.

Screen for psychosocial disorders

As noted earlier, the physical component of obesity is commonly associated with mood disorders such as anxiety and depression.² This requires a multidisciplinary team effort to facilitate healing in the patient struggling with obesity.

Screening for depression and anxiety using standardized tools such as the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 is encouraged in patients who are overweight or obese. Positive screens should be addressed as part of the patient’s treatment plan, as untreated depression and anxiety can inhibit success with weight loss. Be mindful that many medications commonly used to treat these conditions can impair weight loss and even promote weight gain.

Continue to: Don't overlook binge-eating disorders

Don’t overlook binge-eating disorders. Screening specifically for binge-eating disorders is important, given the implications on treatment. The US Department of Veterans Affairs developed a single-item tool for this purpose, the VA Binge Eating Screener. The validated questionnaire asks, “On average, how often have you eaten extremely large amounts of food at one time and felt that your eating was out of control at that time?” Response options are: “Never,” “< 1 time/week,” “1 time/week,” “2-4 times/week,” and “5+ times/week.” A response of ≥ 2 times/week had a sensitivity of 88.9% and specificity of 83.2% for binge-eating disorder.³

For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

Patients with positive screens should undergo psychotherapy and consider pharmacotherapy with lisdexamfetamine as part of their treatment plan. Caution should be used if recommending intermittent fasting for someone with binge-eating disorder.

Evaluate for underlying causes and assess for comorbidities

Review the patient’s current medication list and history. Many medications can cause weight gain, and weight loss can often be achieved by deprescribing such medications. When feasible, prescribe an alternative medication with a more favorable weight profile. A previous article in The Journal of Family Practice addresses this in more depth.⁴

Laboratory and other testing

Laboratory analysis should primarily be focused on determining treatment alterations specific to underlying pathophysiology. Tests to consider ordering are outlined in the Table. Identification of underlying causes and/or comorbid conditions through such testing can guide medication changes, treatment choices, and diet recommendations.

Diabetes and insulin resistance. The American Diabetes Association recommends screening patients who are overweight or obese and have an additional risk factor for diabetes.⁵ This can be done by obtaining a fasting glucose level, hemoglobin A1C, or a 2-hour oral glucose tolerance test.

Continue to: Since it is known that...

Since it is known that insulin resistance increases the risk for coronary heart disease⁶ and can be treated effectively,⁷ we recommend testing for insulin resistance in patients who do not already have impaired fasting glucose, prediabetes, type 2 diabetes, or impaired glucose tolerance. The homeostatic model assessment for insulin resistance (HOMA-IR)⁸ is a measure of insulin resistance and can be calculated from the fasting insulin and fasting glucose levels. This measure should not be done in isolation, but it can be a useful adjunct in identifying patients with insulin resistance and directing treatment.

If there is evidence of diabetes or insulin resistance, consider treatment with metformin ± initiation of a low-carbohydrate diet.

Hypothyroidism. Consider screening for thyroid dysfunction with a thyroid-stimulating hormone level, if it has not been checked previously.

Renal abnormalities. When serum creatinine levels and glomerular filtration rate indicate chronic kidney disease, consider recommending a protein-restricted diet and adjust medications according to renal dosing protocols, as indicated.

Liver abnormalities, including nonalcoholic fatty liver disease (NAFLD). Monitor aspartate aminotransferase and alanine aminotransferase for resolution of elevations as weight loss is achieved. If abnormalities persist, consider ordering a liver ultrasound. Traditionally, low-calorie diets have been prescribed to treat NAFLD, but evidence shows that low-carbohydrate diets can also be effective.⁹

Continue to: Hypertriglyceridemia and low high-density lipoprotein (HDL) levels

Hypertriglyceridemia and low high-density lipoprotein (HDL) levels. Obtain a lipid panel if one has not been completed within the past several years, as hypertriglyceridemia and low HDL can improve dramatically with specific dietary changes.⁷ Observe trends to assess for resolution of lipid abnormalities as weight loss is achieved.

Gout. Consider checking a uric acid level if you are thinking about recommending a low-carbohydrate diet, particularly in patients with a history of gout, as this may temporarily increase the risk of gout flare.

Hypovitaminosis D. If the patient’s vitamin D level is low, consider appropriate supplementation to support the patient’s overall health. While vitamin D deficiency is common in obesity, the role of supplementation in this population is unclear.

Cardiovascular disease. Consider ordering an electrocardiogram, particularly if you are thinking of prescribing medication therapy. Use caution with initiation of certain medications, such as phentermine or diethylproprion, in the presence of arrhythmias or active cardiovascular disease.

Obstructive sleep apnea. Sleep health is important to address, since obesity is one of the most significant risk factors for obstructive sleep apnea.¹⁰ If your patient is given a diagnosis of OSA following a sleep study, consider treatment with continuous positive airway pressure (CPAP), although there are conflicting studies regarding the effects of CPAP therapy in OSA on weight.^11,12

Continue to: Provide guidance on lifestyle changes

Provide guidance on lifestyle changes

Addressing obesity with patients can be challenging in a busy primary care clinic, but it is imperative to helping patients achieve overall health. Counseling on nutrition and physical activity is an important part of this process.

There is no one-size-fits-all approach to nutrition counseling. Focus on creating individualized plans through which patients can achieve success. Some guidance follows, but also beware of common pitfalls that we have observed in clinical practice which, when addressed, can enable significant weight loss (see “Common pitfalls inhibiting weight loss”).

Choose an approach that works for the patient. Commonly prescribed diets to address obesity include, but are not limited to, Atkins, Dietary Approaches to Stop Hypertension (DASH), Glycemic Index, Mediterranean, Ornish, Paleolithic, Zone, whole food plant-based, and ketogenic. We attempt to engage patients in making the decision on what food choices are appropriate for them considering their food availability, culture, and belief systems. For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos.

Rather than focus on a specific diet, which may not be sustainable long term, encourage healthy eating habits. Low-­carbohydrate diets have been shown to promote greater weight loss compared to low-fat diets.^13,14 Low-calorie diets can also be quite effective in promoting short-term weight loss. In our clinic, when weight loss is the primary goal, patients are typically encouraged to focus on either calorie or carbohydrate restriction in the initial stages of weight loss.

Eliminate sugar and refined carbohydrates. While rigorous mortality data are not available, more recent trials have demonstrated significant improvements in atherosclerotic cardiovascular disease risk markers, including weight reduction and diabetes reversal, when following a diet that markedly decreases carbohydrate intake, especially sugar and refined carbohydrates.^7,14-17

Continue to: We recommend that patients focus...

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos. We also recommend substantially limiting or eliminating fruit juices and fruit smoothies due to their high sugar content. For example, 8 oz of orange juice contains 26 g of carbohydrates, which is almost as much as 8 oz of soda.

Compared with eating whole fruit, consuming fruit juice has demonstrated a small amount of weight gain in young children and adults.^18,19 It also has shown a higher insulin response compared with eating the same amount of carbohydrates in whole fruit.²⁰ Better options to drink include water, unsweetened tea, and black coffee. Also, avoid ultra-processed carbohydrates from foods such as breads, cereals, and pastries, as they have similar effects on blood glucose when compared to sugar.²¹

Greatly restrict highly processed foods. The evidence suggests that the availability of processed food is associated with increasing obesity.²² Simple advice to offer your patients is to encourage them to shop the perimeter of the grocery store, where fresh produce, meat, and dairy products are primarily located, and avoid the inner aisles, which contain primarily processed foods. Choosing food items with 5 or fewer ingredients is a starting point when teaching patients to read labels.

Consider limiting saturated fats. In 1977, the Dietary Guidelines for Americans recommended that Americans eat no more than 30% of total energy intake from fat and less than 10% of total energy intake from saturated fat; however, no randomized controlled trials had been done that supported this recommendation and epidemiologic data supporting it were weak.²³

The 2015 Dietary Guidelines continue to recommend limiting total energy intake from saturated fats.²⁴ While there may be a small decrease in cardiovascular risk with a reduction of saturated fat intake and replacement with unsaturated fats, no overall mortality benefit has been demonstrated.^24,25 More research is needed in this area to guide patients in decisions regarding consumption of saturated fats and what types of unsaturated fats are best for their health.

Continue to: Eat only 3 meals per day

Eat only 3 meals per day, but aim for fewer than that. The prescription of fasting is a modality that can be used for weight loss and improved health. Fasting has been a prescribed healing practice for thousands of years.²⁶ It is a practice that virtually every major religion in the world embraces. Studies have demonstrated fasting to be safe and effective in the setting of obesity without significant comorbidities, and it may promote weight loss and metabolic health.^26-29

There are multiple types of intermittent fasting. A practical way for patients to start is by restricting the number of hours in which they eat or drink calorie-containing beverages to 8 hours per day. In our experience, this regimen is easier for most patients to follow than alternate-day or other longer fasts. While there has been caution in the prescription of intermittent fasting due to concerns about causing eating disorders, a recent small study did not demonstrate increased risk of eating disorders with daily intermittent fasting.³⁰

Participate in healthy exercise. Nonpharmacologic office-based strategies for treating obesity have generally focused on increasing exercise and decreasing caloric intake.³¹ While exercise has significant health benefits, including preventing weight regain, evidence does not support monotherapy with exercise as an effective long-term weight-loss strategy.³² There are no studies available that adequately support prescribing an exact dose of exercise.³³ Generally, less than 150 minutes of exercise per week is not effective and more than that does have a dose-related response.³³

Follow up to help patients stay on target

There is no ideal interval for follow-up visits. However, frequent visits—anywhere from weekly to monthly—in the initial stages of weight loss increase the patient’s sense of accountability and, in our experience, seem to be helpful.

Patients may also choose to track their progress by weighing themselves regularly. A small study published in the International Journal of Obesity found that patients who weighed themselves daily had greater and more sustained weight loss than those who didn’t.³⁴ But the decision of whether to weigh one’s self at home should be individualized for each patient.

The validated questionnaire asks, “On average, how often have you eaten extremely large amounts of food at one time and felt that your eating was out of control at that time?” Response options are: “Never,” “< 1 time/week,” “1 time/week,” “2-4 times/week,” and “5+ times/week.” A response of ≥ 2 times/week had a sensitivity of 88.9% and specificity of 83.2% for binge-eating disorder.³

For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

Patients with positive screens should undergo psychotherapy and consider pharmacotherapy with lisdexamfetamine as part of their treatment plan. Caution should be used if recommending intermittent fasting for someone with binge-eating disorder.

Evaluate for underlying causes and assess for comorbidities

Review the patient’s current medication list and history. Many medications can cause weight gain, and weight loss can often be achieved by deprescribing such medications. When feasible, prescribe an alternative medication with a more favorable weight profile. A previous article in The Journal of Family Practice addresses this in more depth.⁴

Laboratory and other testing

Laboratory analysis should primarily be focused on determining treatment alterations specific to underlying pathophysiology. Tests to consider ordering are outlined in the Table. Identification of underlying causes and/or comorbid conditions through such testing can guide medication changes, treatment choices, and diet recommendations.

Diabetes and insulin resistance. The American Diabetes Association recommends screening patients who are overweight or obese and have an additional risk factor for diabetes.⁵ This can be done by obtaining a fasting glucose level, hemoglobin A1C, or a 2-hour oral glucose tolerance test.

Continue to: Since it is known that...

Since it is known that insulin resistance increases the risk for coronary heart disease⁶ and can be treated effectively,⁷ we recommend testing for insulin resistance in patients who do not already have impaired fasting glucose, prediabetes, type 2 diabetes, or impaired glucose tolerance. The homeostatic model assessment for insulin resistance (HOMA-IR)⁸ is a measure of insulin resistance and can be calculated from the fasting insulin and fasting glucose levels. This measure should not be done in isolation, but it can be a useful adjunct in identifying patients with insulin resistance and directing treatment.

If there is evidence of diabetes or insulin resistance, consider treatment with metformin ± initiation of a low-carbohydrate diet.

Hypothyroidism. Consider screening for thyroid dysfunction with a thyroid-stimulating hormone level, if it has not been checked previously.

Renal abnormalities. When serum creatinine levels and glomerular filtration rate indicate chronic kidney disease, consider recommending a protein-restricted diet and adjust medications according to renal dosing protocols, as indicated.

Liver abnormalities, including nonalcoholic fatty liver disease (NAFLD). Monitor aspartate aminotransferase and alanine aminotransferase for resolution of elevations as weight loss is achieved. If abnormalities persist, consider ordering a liver ultrasound. Traditionally, low-calorie diets have been prescribed to treat NAFLD, but evidence shows that low-carbohydrate diets can also be effective.⁹

Continue to: Hypertriglyceridemia and low high-density lipoprotein (HDL) levels

Hypertriglyceridemia and low high-density lipoprotein (HDL) levels. Obtain a lipid panel if one has not been completed within the past several years, as hypertriglyceridemia and low HDL can improve dramatically with specific dietary changes.⁷ Observe trends to assess for resolution of lipid abnormalities as weight loss is achieved.

Gout. Consider checking a uric acid level if you are thinking about recommending a low-carbohydrate diet, particularly in patients with a history of gout, as this may temporarily increase the risk of gout flare.

Hypovitaminosis D. If the patient’s vitamin D level is low, consider appropriate supplementation to support the patient’s overall health. While vitamin D deficiency is common in obesity, the role of supplementation in this population is unclear.

Cardiovascular disease. Consider ordering an electrocardiogram, particularly if you are thinking of prescribing medication therapy. Use caution with initiation of certain medications, such as phentermine or diethylproprion, in the presence of arrhythmias or active cardiovascular disease.

Obstructive sleep apnea. Sleep health is important to address, since obesity is one of the most significant risk factors for obstructive sleep apnea.¹⁰ If your patient is given a diagnosis of OSA following a sleep study, consider treatment with continuous positive airway pressure (CPAP), although there are conflicting studies regarding the effects of CPAP therapy in OSA on weight.^11,12

Provide guidance on lifestyle changes

Addressing obesity with patients can be challenging in a busy primary care clinic, but it is imperative to helping patients achieve overall health. Counseling on nutrition and physical activity is an important part of this process.

There is no one-size-fits-all approach to nutrition counseling. Focus on creating individualized plans through which patients can achieve success. Some guidance follows, but also beware of common pitfalls that we have observed in clinical practice which, when addressed, can enable significant weight loss (see “Common pitfalls inhibiting weight loss”).

Choose an approach that works for the patient. Commonly prescribed diets to address obesity include, but are not limited to, Atkins, Dietary Approaches to Stop Hypertension (DASH), Glycemic Index, Mediterranean, Ornish, Paleolithic, Zone, whole food plant-based, and ketogenic. We attempt to engage patients in making the decision on what food choices are appropriate for them considering their food availability, culture, and belief systems. For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos.

Rather than focus on a specific diet, which may not be sustainable long term, encourage healthy eating habits. Low-­carbohydrate diets have been shown to promote greater weight loss compared to low-fat diets.^13,14 Low-calorie diets can also be quite effective in promoting short-term weight loss. In our clinic, when weight loss is the primary goal, patients are typically encouraged to focus on either calorie or carbohydrate restriction in the initial stages of weight loss.

Eliminate sugar and refined carbohydrates. While rigorous mortality data are not available, more recent trials have demonstrated significant improvements in atherosclerotic cardiovascular disease risk markers, including weight reduction and diabetes reversal, when following a diet that markedly decreases carbohydrate intake, especially sugar and refined carbohydrates.^7,14-17

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos. We also recommend substantially limiting or eliminating fruit juices and fruit smoothies due to their high sugar content. For example, 8 oz of orange juice contains 26 g of carbohydrates, which is almost as much as 8 oz of soda.

Compared with eating whole fruit, consuming fruit juice has demonstrated a small amount of weight gain in young children and adults.^18,19 It also has shown a higher insulin response compared with eating the same amount of carbohydrates in whole fruit.²⁰ Better options to drink include water, unsweetened tea, and black coffee. Also, avoid ultra-processed carbohydrates from foods such as breads, cereals, and pastries, as they have similar effects on blood glucose when compared to sugar.²¹

Greatly restrict highly processed foods. The evidence suggests that the availability of processed food is associated with increasing obesity.²² Simple advice to offer your patients is to encourage them to shop the perimeter of the grocery store, where fresh produce, meat, and dairy products are primarily located, and avoid the inner aisles, which contain primarily processed foods. Choosing food items with 5 or fewer ingredients is a starting point when teaching patients to read labels.

Consider limiting saturated fats. In 1977, the Dietary Guidelines for Americans recommended that Americans eat no more than 30% of total energy intake from fat and less than 10% of total energy intake from saturated fat; however, no randomized controlled trials had been done that supported this recommendation and epidemiologic data supporting it were weak.²³

The 2015 Dietary Guidelines continue to recommend limiting total energy intake from saturated fats.²⁴ While there may be a small decrease in cardiovascular risk with a reduction of saturated fat intake and replacement with unsaturated fats, no overall mortality benefit has been demonstrated.^24,25 More research is needed in this area to guide patients in decisions regarding consumption of saturated fats and what types of unsaturated fats are best for their health.

Continue to: Eat only 3 meals per day

Eat only 3 meals per day, but aim for fewer than that. The prescription of fasting is a modality that can be used for weight loss and improved health. Fasting has been a prescribed healing practice for thousands of years.²⁶ It is a practice that virtually every major religion in the world embraces. Studies have demonstrated fasting to be safe and effective in the setting of obesity without significant comorbidities, and it may promote weight loss and metabolic health.^26-29

There are multiple types of intermittent fasting. A practical way for patients to start is by restricting the number of hours in which they eat or drink calorie-containing beverages to 8 hours per day. In our experience, this regimen is easier for most patients to follow than alternate-day or other longer fasts. While there has been caution in the prescription of intermittent fasting due to concerns about causing eating disorders, a recent small study did not demonstrate increased risk of eating disorders with daily intermittent fasting.³⁰

Participate in healthy exercise. Nonpharmacologic office-based strategies for treating obesity have generally focused on increasing exercise and decreasing caloric intake.³¹ While exercise has significant health benefits, including preventing weight regain, evidence does not support monotherapy with exercise as an effective long-term weight-loss strategy.³² There are no studies available that adequately support prescribing an exact dose of exercise.³³ Generally, less than 150 minutes of exercise per week is not effective and more than that does have a dose-related response.³³

Follow up to help patients stay on target

There is no ideal interval for follow-up visits. However, frequent visits—anywhere from weekly to monthly—in the initial stages of weight loss increase the patient’s sense of accountability and, in our experience, seem to be helpful.

Patients may also choose to track their progress by weighing themselves regularly. A small study published in the International Journal of Obesity found that patients who weighed themselves daily had greater and more sustained weight loss than those who didn’t.³⁴ But the decision of whether to weigh one’s self at home should be individualized for each patient.

In 2015-2016, almost 40% of adults and 18.5% of children ages 2 to 19 years in the United States met the definition for obesity—a chronic, relapsing, multifactorial, neurobehavioral disease that results in adverse metabolic, biomechanical, and psychosocial health consequences.^1,2

Tremendous resources have been invested in research, policy development, and public education to try to prevent obesity and its related complications. Despite this, the obesity epidemic has worsened. Here, we explore how to evaluate and treat obese patients in a primary care setting based on the evidence and our experience seeing patients specifically for weight management in a family medicine residency teaching clinic. Pharmacotherapy and surgery, while often helpful, are outside the scope of this article.

It begins withan obesity-friendly office

Patients may have reservations about health care interactions specific to obesity, so it is important to invite them into a setting that facilitates trust and encourages collaboration. Actively engage patients with unhealthy weight by creating an environment where they feel comfortable. Offer wide chairs without armrests, which will easily accommodate patients of all sizes, and ensure that scales have a weight capacity > 400 lb. Communicate a message to patients, via waiting room materials and videos, that focuses on health rather than on weight or body mass index (BMI).

Understand the patient’s goals and challenges

Most (although not all) family physicians will see obese patients in the context of a visit for diabetes, hypertension, or another condition. However, we feel that having visits specifically to address weight in the initial stages of weight management is helpful. The focus of an initial visit should be getting to know how obesity has affected the patient and what his or her motive is in attempting to lose weight. Explore previous attempts at weight loss and establish what the patient’s highest weight has been, as this will impact weight-loss goals. For example, if a patient has weighed > 300 lb all her adult life, it will be extremely difficult to maintain a weight loss of 150 lb.

What else to ask about. Discuss stressors that may be causing increased food intake or poor food choices, including hunger, anger, loneliness, and sleep difficulties. Multidisciplinary care including a psychologist can aid in addressing these issues. Ask patients if they keep a food diary (and if not, recommend that they start), as food diaries are often helpful in elucidating eating and drinking patterns. Determine a patient’s current and past levels of physical activity, as this will guide the fitness goals you develop for him or her.

Screen for psychosocial disorders

As noted earlier, the physical component of obesity is commonly associated with mood disorders such as anxiety and depression.² This requires a multidisciplinary team effort to facilitate healing in the patient struggling with obesity.

Screening for depression and anxiety using standardized tools such as the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 is encouraged in patients who are overweight or obese. Positive screens should be addressed as part of the patient’s treatment plan, as untreated depression and anxiety can inhibit success with weight loss. Be mindful that many medications commonly used to treat these conditions can impair weight loss and even promote weight gain.

Patients with rheumatic heart disease (RHD) appear to have comparable outcomes, whether undergoing transcatheter or surgical aortic valve replacement (TAVR/SAVR), and when compared with TAVR in patients with nonrheumatic aortic stenosis, a new Medicare study finds.

An analysis of data from 1,159 Medicare beneficiaries with rheumatic aortic stenosis revealed that, over a median follow-up of 19 months, there was no difference in all-cause mortality with TAVR vs. SAVR (11.2 vs. 7.0 per 100 person-years; adjusted hazard ratio, 1.53; P = .2).

Mortality was also similar after a median follow-up of 17 months between TAVR in patients with rheumatic aortic stenosis and 88,554 additional beneficiaries with nonrheumatic aortic stenosis (15.2 vs. 17.7 deaths per 100 person-years; aHR, 0.87; P = .2).

“We need collaboration between industry and society leaders in developed countries to initiate a randomized, controlled trial to address the feasibility of TAVR in rheumatic heart disease in younger populations who aren’t surgical candidates or if there’s a lack of surgical capabilities in countries, but this is an encouraging first sign,” lead author Amgad Mentias, MD, MSc, Cleveland Clinic Foundation, said in an interview.

Although the prevalence of rheumatic heart disease (RHD) has fallen to less than 5% or so in the United States and Europe, it remains a significant problem in developing and low-income countries, with more than 1 million deaths per year, he noted. RHD patients typically present at younger ages, often with concomitant aortic regurgitation and mitral valve disease, but have less calcification than degenerative calcific aortic stenosis.

Commenting on the results, published in the Journal of the American College of Cardiology, David F. Williams, PhD, said in an interview that “it is only now becoming possible to entertain the use of TAVR in such patients, and this paper demonstrates the feasibility of doing so.

“Although the study is based on geriatric patients of an industrialized country, it opens the door to the massive unmet clinical needs in poorer regions as well as emerging economies,” said Dr. Williams, a professor at the Wake Forest Institute for Regenerative Medicine, Winston-Salem, N.C., and coauthor of an accompanying editorial.

The study included Medicare beneficiaries treated from October 2015 to December 2017 for rheumatic aortic stenosis (TAVR, n = 605; SAVR, n = 55) or nonrheumatic aortic stenosis (n = 88,554).

Among those with rheumatic disease, SAVR patients were younger than TAVR patients (73.4 vs. 79.4 years), had a lower prevalence of most comorbidities, and were less frail (median frailty score, 5.3 vs. 11.3).

SAVR was associated with significantly higher weighted risk for in-hospital acute kidney injury (22.3% vs. 11.9%), blood transfusion (19.8% vs. 7.6%), cardiogenic shock (5.7% vs. 1.5%), new-onset atrial fibrillation (21.1% vs. 2.2%), and had longer hospital stays (median, 8 vs. 3 days), whereas new permanent pacemaker implantations trended higher with TAVR (12.5% vs 7.2%).

The TAVR and SAVR groups had comparable rates of adjusted in-hospital mortality (2.4% vs. 3.5%), 30-day mortality (3.6% vs. 3.2%), 30-day stroke (2.4% vs. 2.8%), and 1-year mortality (13.1% vs. 8.9%).

Among the two TAVR cohorts, patients with rheumatic disease were younger than those with nonrheumatic aortic stenosis (79.4 vs. 81.2 years); had a higher prevalence of heart failure, ischemic stroke, atrial fibrillation, and lung disease; and were more frail (median score, 11.3 vs. 6.9).

Still, there was no difference in weighted risk of in-hospital mortality (2.2% vs. 2.6%), 30-day mortality (3.6% vs. 3.7%), 30-day stroke (2.0% vs. 3.3%), or 1-year mortality (16.0% vs. 17.1%) between TAVR patients with and without rheumatic stenosis.

“We didn’t have specific information on echo[cardiography], so we don’t know how that affected our results, but one of the encouraging points is that after a median follow-up of almost 2 years, none of the patients who had TAVR in the rheumatic valve and who survived required redo aortic valve replacement,” Dr. Mentias said. “It’s still short term but it shows that for the short to mid term, the valve is durable.”

Data were not available on paravalvular regurgitation, an Achilles heel for TAVR, but Dr. Mentias said rates of this complication have come down significantly in the past 2 years with modifications to newer-generation TAVR valves.

Dr. Williams and colleagues say one main limitation of the study also highlights the major shortcoming of contemporary TAVRs when treating patients with RHD: “namely, their inadequate suitability for AR [aortic regurgitation], the predominant rheumatic lesion of the aortic valve” in low- to middle-income countries.

They pointed out that patients needing an aortic valve where RHD is rampant are at least 30 years younger than the 79-year-old TAVR recipients in the study.

In a comment, Dr. Williams said there are several unanswered questions about the full impact TAVR could have in the treatment of young RHD patients in underprivileged regions. “These mainly concern the durability of the valves in individuals who could expect greater longevity than the typical heart valve patient in the USA, and the adaptation of transcatheter techniques to provide cost-effective treatment in regions that lack the usual sophisticated clinical infrastructure.”

Dr. Mentias received support from a National Research Service Award institutional grant to the Abboud Cardiovascular Research Center. Dr. Williams and coauthors are directors of Strait Access Technologies.

“We didn’t have specific information on echo[cardiography], so we don’t know how that affected our results, but one of the encouraging points is that after a median follow-up of almost 2 years, none of the patients who had TAVR in the rheumatic valve and who survived required redo aortic valve replacement,” Dr. Mentias said. “It’s still short term but it shows that for the short to mid term, the valve is durable.”

Data were not available on paravalvular regurgitation, an Achilles heel for TAVR, but Dr. Mentias said rates of this complication have come down significantly in the past 2 years with modifications to newer-generation TAVR valves.

Dr. Williams and colleagues say one main limitation of the study also highlights the major shortcoming of contemporary TAVRs when treating patients with RHD: “namely, their inadequate suitability for AR [aortic regurgitation], the predominant rheumatic lesion of the aortic valve” in low- to middle-income countries.

They pointed out that patients needing an aortic valve where RHD is rampant are at least 30 years younger than the 79-year-old TAVR recipients in the study.

In a comment, Dr. Williams said there are several unanswered questions about the full impact TAVR could have in the treatment of young RHD patients in underprivileged regions. “These mainly concern the durability of the valves in individuals who could expect greater longevity than the typical heart valve patient in the USA, and the adaptation of transcatheter techniques to provide cost-effective treatment in regions that lack the usual sophisticated clinical infrastructure.”

Patients with rheumatic heart disease (RHD) appear to have comparable outcomes, whether undergoing transcatheter or surgical aortic valve replacement (TAVR/SAVR), and when compared with TAVR in patients with nonrheumatic aortic stenosis, a new Medicare study finds.

An analysis of data from 1,159 Medicare beneficiaries with rheumatic aortic stenosis revealed that, over a median follow-up of 19 months, there was no difference in all-cause mortality with TAVR vs. SAVR (11.2 vs. 7.0 per 100 person-years; adjusted hazard ratio, 1.53; P = .2).

Mortality was also similar after a median follow-up of 17 months between TAVR in patients with rheumatic aortic stenosis and 88,554 additional beneficiaries with nonrheumatic aortic stenosis (15.2 vs. 17.7 deaths per 100 person-years; aHR, 0.87; P = .2).

“We need collaboration between industry and society leaders in developed countries to initiate a randomized, controlled trial to address the feasibility of TAVR in rheumatic heart disease in younger populations who aren’t surgical candidates or if there’s a lack of surgical capabilities in countries, but this is an encouraging first sign,” lead author Amgad Mentias, MD, MSc, Cleveland Clinic Foundation, said in an interview.

Although the prevalence of rheumatic heart disease (RHD) has fallen to less than 5% or so in the United States and Europe, it remains a significant problem in developing and low-income countries, with more than 1 million deaths per year, he noted. RHD patients typically present at younger ages, often with concomitant aortic regurgitation and mitral valve disease, but have less calcification than degenerative calcific aortic stenosis.

Commenting on the results, published in the Journal of the American College of Cardiology, David F. Williams, PhD, said in an interview that “it is only now becoming possible to entertain the use of TAVR in such patients, and this paper demonstrates the feasibility of doing so.

“Although the study is based on geriatric patients of an industrialized country, it opens the door to the massive unmet clinical needs in poorer regions as well as emerging economies,” said Dr. Williams, a professor at the Wake Forest Institute for Regenerative Medicine, Winston-Salem, N.C., and coauthor of an accompanying editorial.

The study included Medicare beneficiaries treated from October 2015 to December 2017 for rheumatic aortic stenosis (TAVR, n = 605; SAVR, n = 55) or nonrheumatic aortic stenosis (n = 88,554).

Among those with rheumatic disease, SAVR patients were younger than TAVR patients (73.4 vs. 79.4 years), had a lower prevalence of most comorbidities, and were less frail (median frailty score, 5.3 vs. 11.3).

SAVR was associated with significantly higher weighted risk for in-hospital acute kidney injury (22.3% vs. 11.9%), blood transfusion (19.8% vs. 7.6%), cardiogenic shock (5.7% vs. 1.5%), new-onset atrial fibrillation (21.1% vs. 2.2%), and had longer hospital stays (median, 8 vs. 3 days), whereas new permanent pacemaker implantations trended higher with TAVR (12.5% vs 7.2%).

The TAVR and SAVR groups had comparable rates of adjusted in-hospital mortality (2.4% vs. 3.5%), 30-day mortality (3.6% vs. 3.2%), 30-day stroke (2.4% vs. 2.8%), and 1-year mortality (13.1% vs. 8.9%).

Among the two TAVR cohorts, patients with rheumatic disease were younger than those with nonrheumatic aortic stenosis (79.4 vs. 81.2 years); had a higher prevalence of heart failure, ischemic stroke, atrial fibrillation, and lung disease; and were more frail (median score, 11.3 vs. 6.9).

Still, there was no difference in weighted risk of in-hospital mortality (2.2% vs. 2.6%), 30-day mortality (3.6% vs. 3.7%), 30-day stroke (2.0% vs. 3.3%), or 1-year mortality (16.0% vs. 17.1%) between TAVR patients with and without rheumatic stenosis.

“We didn’t have specific information on echo[cardiography], so we don’t know how that affected our results, but one of the encouraging points is that after a median follow-up of almost 2 years, none of the patients who had TAVR in the rheumatic valve and who survived required redo aortic valve replacement,” Dr. Mentias said. “It’s still short term but it shows that for the short to mid term, the valve is durable.”

Cardiovascular and metabolic risk factors are increased among transgender youths, compared with youths who are not transgender. Elevations in lipid levels and body mass index (BMI) also occur in adult transgender patients, new research shows.

“This is the first study of its size in the United States of which we are aware that looks at the odds of youth with a diagnosis of gender dysphoria having medical diagnoses that relate to overall metabolic and cardiovascular health,” first author Anna Valentine, MD, of Children’s Hospital Colorado, Aurora, said in a press statement.

Although previous studies have shown that among transgender adults, BMI is higher and there is an increased risk for cardiovascular events, such as stroke or heart attack, compared with nontransgender people, research on adolescent transgender patients has been lacking.

With a recent survey showing that nearly 2% of adolescents identify as transgender, interest in health outcomes among younger patients is high.

To investigate, Dr. Valentine, and colleagues evaluated data from the PEDSnet pediatric database on 4,177 youths who had received a diagnosis of gender dysphoria. The participants had been enrolled at six sites from 2009 to 2019. The researchers compared these patients in a ratio of 1:4 with 16,664 control persons who had not been diagnosed with gender dysphoria. They reported their findings as a poster at the annual meeting of the Endocrine Society.

For the propensity-score analysis, participants were matched according to year of birth, age at last visit, site, race, ethnicity, insurance status, and duration in the database.

In both the transgender and control groups, about 66% were female at birth, 73% were White, and 9% Hispanic. For both groups, the average age was 16.2 years at the last visit. The average duration in the database was 7 years.
 

Study didn’t distinguish between those receiving and those not receiving gender-affirming hormones

In the retrospective study, among those who identified as transgender, the rates of diagnoses of dyslipidemia (odds ratio, 1.6; P < .0001) and metabolic syndrome (OR, 1.9; P = .0086) were significantly higher, compared with those without gender dysphoria.

Among the transgender male patients (born female) but not transgender female patients (born male), rates of diagnoses of overweight/obesity (OR, 1.7; P < .0001) and polycystic ovary syndrome were higher (OR, 1.9, P = .0006), compared with controls.

Gender-affirming hormone therapy, such as with testosterone or estradiol, is among the suspected culprits for the cardiovascular effects. However, importantly, this study did not differentiate between patients who had received estradiol or testosterone for gender affirmation and those who had not, Dr. Valentine said.

“We don’t know [whether gender-affirming hormone therapy is a cause], as we have not looked at this yet,” she said in an interview. “We are looking at that in our next analyses and will be including that in our future publication.

“We’ll also be looking at the relationship between having overweight/obesity and the other diagnoses that influence cardiovascular health (high blood pressure, liver dysfunction, and abnormal cholesterol), as that could certainly be playing a role as well,” she said.

For many transgender patients, gender-affirming hormone therapy is lifelong. One question that needs to be evaluated concerns whether the dose of such therapy has a role on cardiovascular effects and if so, whether adjustments could be made without compromising the therapeutic effect, Dr. Valentine noted.

“This is an important question, and future research is needed to evaluate whether doses [of gender-affirming hormones] are related to cardiometabolic outcomes,” she said.

Potential confounders in the study include the fact that rates of overweight and obesity are higher among youths with gender dysphoria. This can in itself can increase the risk for other disorders, Dr. Valentine noted.

Furthermore, rates of mental health comorbidities are higher among youths with gender dysphoria. One consequence of this may be that they engage in less physical activity, she said.
 

Hormone therapy, health care disparities, or both could explain risk

In commenting on the study, Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery, the Mount Sinai Health System, New York, said that although similar cardiovascular effects are known to occur in transgender adults as well, they may or may not be hormone related. Other factors can increase the risk.

“With transgender adults, any differences in lipids or cardiac risk factors relative to cisgender people might be attributable either to hormone therapy or to health care disparities,” he said in an interview.

“The data are mixed. It may be that most differences relate to lack of access to care and to mistreatment by society,” he said. “Even studies that focus on hormones see a worsened situation for trans women versus trans men.”

Other recent research that shows potential cardiovascular effects among adult transgender men includes a study of more than 1,000 transgender men (born female) who received testosterone. That study, which was also presented at the ENDO meeting and was reported by this news organization, found an increased risk for high hematocrit levels, which could lead to a thrombotic event.

However, a study published in Pediatrics, which was also reported by this news organization, that included 611 transgender youths who had taken gender-affirming hormone therapy for more than a year found no increased risk for thrombosis, even in the presence of thrombosis risk factors, including obesity, tobacco use, and family history of thrombosis. However, the senior author of that study pointed out that the duration of follow-up in that study was relatively short, which may have been why they did not find an increased risk for thrombosis.

Dr. Safer noted that transgender youths and adults alike face a host of cultural factors that could play a role in increased cardiovascular risks.

“For adults, the major candidate explanations for worse BMI and cardiac risk factors are societal mistreatment, and for trans women specifically, progestins. For youth, the major candidate explanations are societal mistreatment and lack of access to athletics,” he said.

The authors and Dr. Safer disclosed no relevant financial relationships.

The incidence of venous thromboembolism (VTE) in nonhospitalized patients with COVID-19 was not significantly different from patients without the infectious disease, according to a new study published in JAMA Internal Medicine.

National Institutes of Health guidelines recommend blood thinners to prevent blood clots in patients hospitalized with COVID-19. However, the new study provides more insight on the best treatment approach for COVID-19 outpatients.

“[COVID-19’s] rapid global progression and impact has caused us to make and modify treatment decisions at a pace that we never have in modern medicine,” study author Nareg Roubinian, MD, an investigator at Kaiser Permanente, Oakland, Calif., said in an interview.

“As with other potential therapies for COVID-19, blood thinners need to be prospectively studied in a clinical trial to determine if they improve patient outcomes,” Dr. Roubinian added.

The increased risk of blood clots in patients hospitalized with COVID-19 has been a major issue throughout the pandemic. In fact, one study published in November 2020 found that more than half of patients hospitalized with the illness have prothrombotic antiphospholipid (aPL) autoantibodies in their blood, which could contribute to venous and arterial thromboembolism.

Although it was clear many hospitalized patients diagnosed with COVID-19 were developing more clots, researchers of the current study were not sure if this trend would also be seen in outpatients.

“Most people with COVID-19 do not need to be hospitalized, and we needed to know how often patients outside the hospital were having blood clots,” said Dr. Roubinian.

For the study, Dr. Roubinian and colleagues examined data on 220,588 patients who were members of Kaiser Permanente Northern California health plan and were tested for COVID-19 between Feb. 25 and Aug. 31, 2020. They then reported on the 30-day incidence of outpatient and hospital-associated blood clots following the COVID-19 diagnosis. Patients who were asymptomatic at the time of testing or had received anticoagulants within the last year were excluded.

“We knew from other studies that patients with COVID-19 often get sicker in the first few weeks after infection. What we didn’t know was whether COVID-19 patients were developing blood clots but not pneumonia or were developing blood clots at the same time as they developed pneumonia,” said Dr. Roubinian, an intensive care doctor with the Permanente Medical Group in Oakland, Calif. “Following the patients for 30 days allowed us to focus on the time period from infection to when blood clots were most likely to develop.”

Researchers found that of the cohort who took the COVID-19 test, 11.8% had a positive result. Within 30 days of the COVID-19 test, 0.8% of patients with a positive result were diagnosed with VTE compared to 0.5% of those who received a negative test result. They also found that viral testing took place in an outpatient setting for 59.1% of the patients with a positive viral test who later developed VTE. Of those patients, 76.1% had to be hospitalized.

Dr. Roubinian said he was surprised to see that the blood clotting in outpatients with COVID-19 was similar in frequency to what he saw in patients without the infection.

“Our findings suggest that blood clots do occur in COVID-19 patients but not on a scale where we need to put all or many COVID outpatients on blood thinners,” he said. “As with other potential therapies for COVID-19, blood thinners need to be prospectively studied in a clinical trial to determine if they improve patient outcomes.”

In December 2020, three trials investigating the risk and benefits of increased levels of anticoagulation in hospitalized COVID-19 patients were paused because of safety issues. The trials would have enrolled critically ill COVID-19 patients for whom therapeutic doses of anticoagulation drugs showed no benefit.

Anticoagulants are associated with bleeding risks, including prolonged nosebleeds and vomiting or coughing up blood.

Instead of prescribing the routine use of thromboprophylactic drugs to COVID-19 outpatients, Dr. Roubinian believes it would be helpful to learn how to determine whether a patient at risk of becoming sick or being hospitalized would benefit from being treated with such drugs.

Dr. Roubinian reported receiving grants from the National Institutes of Health and the National Heart, Lung, and Blood Institute during the conduct of the study.

Instead of prescribing the routine use of thromboprophylactic drugs to COVID-19 outpatients, Dr. Roubinian believes it would be helpful to learn how to determine whether a patient at risk of becoming sick or being hospitalized would benefit from being treated with such drugs.

Dr. Roubinian reported receiving grants from the National Institutes of Health and the National Heart, Lung, and Blood Institute during the conduct of the study.
 

The incidence of venous thromboembolism (VTE) in nonhospitalized patients with COVID-19 was not significantly different from patients without the infectious disease, according to a new study published in JAMA Internal Medicine.

National Institutes of Health guidelines recommend blood thinners to prevent blood clots in patients hospitalized with COVID-19. However, the new study provides more insight on the best treatment approach for COVID-19 outpatients.

“[COVID-19’s] rapid global progression and impact has caused us to make and modify treatment decisions at a pace that we never have in modern medicine,” study author Nareg Roubinian, MD, an investigator at Kaiser Permanente, Oakland, Calif., said in an interview.

“As with other potential therapies for COVID-19, blood thinners need to be prospectively studied in a clinical trial to determine if they improve patient outcomes,” Dr. Roubinian added.

The increased risk of blood clots in patients hospitalized with COVID-19 has been a major issue throughout the pandemic. In fact, one study published in November 2020 found that more than half of patients hospitalized with the illness have prothrombotic antiphospholipid (aPL) autoantibodies in their blood, which could contribute to venous and arterial thromboembolism.

Although it was clear many hospitalized patients diagnosed with COVID-19 were developing more clots, researchers of the current study were not sure if this trend would also be seen in outpatients.

“Most people with COVID-19 do not need to be hospitalized, and we needed to know how often patients outside the hospital were having blood clots,” said Dr. Roubinian.

For the study, Dr. Roubinian and colleagues examined data on 220,588 patients who were members of Kaiser Permanente Northern California health plan and were tested for COVID-19 between Feb. 25 and Aug. 31, 2020. They then reported on the 30-day incidence of outpatient and hospital-associated blood clots following the COVID-19 diagnosis. Patients who were asymptomatic at the time of testing or had received anticoagulants within the last year were excluded.

“We knew from other studies that patients with COVID-19 often get sicker in the first few weeks after infection. What we didn’t know was whether COVID-19 patients were developing blood clots but not pneumonia or were developing blood clots at the same time as they developed pneumonia,” said Dr. Roubinian, an intensive care doctor with the Permanente Medical Group in Oakland, Calif. “Following the patients for 30 days allowed us to focus on the time period from infection to when blood clots were most likely to develop.”

Researchers found that of the cohort who took the COVID-19 test, 11.8% had a positive result. Within 30 days of the COVID-19 test, 0.8% of patients with a positive result were diagnosed with VTE compared to 0.5% of those who received a negative test result. They also found that viral testing took place in an outpatient setting for 59.1% of the patients with a positive viral test who later developed VTE. Of those patients, 76.1% had to be hospitalized.

Dr. Roubinian said he was surprised to see that the blood clotting in outpatients with COVID-19 was similar in frequency to what he saw in patients without the infection.

“Our findings suggest that blood clots do occur in COVID-19 patients but not on a scale where we need to put all or many COVID outpatients on blood thinners,” he said. “As with other potential therapies for COVID-19, blood thinners need to be prospectively studied in a clinical trial to determine if they improve patient outcomes.”

In December 2020, three trials investigating the risk and benefits of increased levels of anticoagulation in hospitalized COVID-19 patients were paused because of safety issues. The trials would have enrolled critically ill COVID-19 patients for whom therapeutic doses of anticoagulation drugs showed no benefit.

Cardiovascular disease was the leading cause of death among the over 16,000 patients with type 2 diabetes (T2DM) who were enrolled in the SAVOR-TIMI 53 trial.

Two-thirds (66.3%) of all 798 deaths after a median 2.1 years of follow-up were caused by one of five cardiovascular (CV) conditions, with sudden cardiac death accounting for the largest share (30.1%) of the total, Ilaria Cavallari, MD, PhD, and associates said in the Journal of the American College of Cardiology.

Most common among the non-CV causes was malignancy at 13.9% of all deaths in a T2DM population at high/very high risk for CV disease (n = 16,492), followed by infection (9.3%), the members of the TIMI Study Group noted.

After variables independently associated with overall mortality were identified, a subdistribution of competing risks was constructed using a competing-risk analysis based on the proportional hazards model, they explained.

Prior heart failure was the clinical variable most associated with CV death and could, along with older age, worse glycemic control, prior CV events, peripheral artery disease, and kidney complications, “identify a subgroup of T2DM patients at high risk of mortality who are likely to achieve the greatest benefit from aggressive management of modifiable risk factors and newer glucose-lowering agents,” the investigators wrote.

It was a pair of laboratory measurements, however, that had the largest subdistribution hazard ratios. “Interestingly, the magnitude of associations of abnormal N-terminal pro–B-type natriuretic peptide [sHR, 2.82] and high-sensitivity troponin T [sHR, 2.46] measured in a stable population were greater than clinical variables in the prediction of all causes of death,” Dr. Cavallari and associates said.

In a new randomized trial that investigated the question of whether thrombolysis can be omitted for patients with stroke who are undergoing endovascular thrombectomy for a large-vessel occlusion, results were similar for both approaches.

The MR CLEAN NO IV trial failed to show superiority or noninferiority of direct endovascular treatment over intravenous alteplase (tissue plasminogen activator, tPA) followed by endovascular treatment, and functional outcomes were not significantly different. In addition, hemorrhage rates with or without intravenous alteplase administration before endovascular treatment were similar.

“From the MR CLEAN NO IV results, we cannot change standard practice, as we failed to show superiority of the direct endovascular approach, and we also didn’t meet the noninferiority criteria. So, the standard practice of giving tPA to those eligible still holds,” said co–lead investigator Yvo Roos, MD.

“But I think we can say that these results suggest that there may also not be such a need for tPA in patients who can go straight for endovascular therapy,” said Dr. Roos, who is professor of neurology at Amsterdam Medical Center.

“If we are not sure whether a patient is suitable for tPA because they have a higher bleeding risk, I think we can be reassured about missing the tPA out and going straight to endovascular treatment. So, if in doubt, leave it out,” he added.

Results of the MR CLEAN NO IV trial were presented at the International Stroke Conference sponsored by the American Heart Association.
 

“If in doubt, leave it out”

Dr. Roos noted that three trials have investigated the question regarding dropping thrombolysis for patients who can receive thrombectomy quickly. These are the DIRECT MT, SKIP, and DEVT studies. All of these trials were conducted in Asian countries, and none found differences in functional outcomes between the two approaches.

The largest of these studies – the DIRECT-MT trial, from China, which was a sister study to MR CLEAN NO IV – did show noninferiority of the direct endovascular approach to tPA plus endovascular treatment.

But because of differences in health care logistics and trial populations, the benefits and risks of dropping thrombolysis in Western countries are not known, explained Charles Majoie, MD, who is co–lead investigator of the current trial and is chair of neuroradiology at Amsterdam Medical Center.

The MR CLEAN NO IV trial was designed to show superiority of the direct endovascular approach with noninferiority for hemorrhage. It enrolled 540 European patients who were eligible for both thrombolysis and thrombectomy and who presented to a thrombectomy-capable center. They were randomly assigned to receive thrombolysis plus endovascular therapy or direct endovascular therapy alone.

The mean time from stroke onset to groin puncture (the start of endovascular therapy) was very fast in both groups – 130 minutes in the direct group, and 135 minutes in the tPA group.

The primary outcome was a shift analysis of the Modified Rankin Scale (mRS). On that outcome, the trial failed to show significant superiority of the direct approach (odds ratio, 0.88; 95% confidence interval, 0.65-1.19).

A good functional outcome (mRS, 0-2) was achieved in 49% of the direct thrombectomy group and in 51% of the tPA group (OR, 0.95; 95% CI, 0.65-1.40).

Safety results showed no difference in any of the hemorrhage endpoints between the two groups. The rate of symptomatic intracranial hemorrhage was actually numerically higher in the direct thrombectomy group (5.9% vs. 5.3%).

“One of the most intriguing results of this study is that there was no increase in hemorrhage in the tPA group,” Dr. Roos commented. “This is very surprising, as we have always thought thrombolysis causes an increased bleeding risk. But after these results, we may have to rethink that idea – perhaps it is not the tPA itself that causes bleeding risk but rather the opening up of the vessel.”

On the failure to show noninferiority of the direct approach, Dr. Roos suggested that the trial may have been underpowered in this respect.

“Our sister trial, DIRECT-MT, was a noninferiority study. They had 650 patients, and they just reached noninferiority,” he said. “In MR CLEAN NO IV, we were aiming for superiority, and we had fewer patients – 540. We didn’t show superiority, and we didn’t have quite enough patients to show noninferiority.”

He added that, considering all the four studies together, the results look very similar and suggest no difference between the two approaches.
 

Individualized approach probable

Dr. Majoie suggested that different patients may be suitable for the different approaches.

“I think we are heading for individualized treatment. If we have a young patient and the angiography suite is ready, we could probably skip tPA, but it would be for the neurologist/neuroradiologist to make individualized decisions on this,” he said. “We need to look at subgroups for more information.”

Another large trial that investigated this issue, SWIFT-DIRECT, is expected to be presented later this year. An Australian trial, DIRECT-SAFE, is ongoing and is at an early stage of recruitment.

Dr. Roos said that the data from all the trials will be combined for a more comprehensive analysis of the benefits and risks of the two approaches in various subgroups.

Commenting on the study was cochair of the ISC session at which it was presented, Tudor Jovin, MD, chair of neurology at Cooper University Hospital, Cherry Hill, N.J.

“Putting these results together with the previous Asian studies, I think we can say that direct thrombectomy without tPA is clearly not superior to the combined approach of tPA plus thrombectomy,” he said.

Dr. Jovin explained that, in theory, direct thrombectomy could be faster than the combined approach and that the risk for symptomatic intracerebral hemorrhage could be lower. But neither of these two possible benefits were seen in this study.

He agreed with Dr. Roos that MR CLEAN NO IV could have failed to show noninferiority of the direct strategy because the sample was not large enough.

“The results of the two approaches are very similar in this study and in the Asian studies, so it doesn’t appear that tPA adds very much, and it is associated with a significant increase in costs,” he said.

“The answer will probably be that there is not a ‘one-size-fits-all’ strategy, and we may end up using different approaches for different patient groups,” Dr. Jovin added. “Information on this will come from subgroups analyses from these trials.”

MR CLEAN NO-IV trial was part of the CONTRAST consortium, which is supported by the Netherlands Cardiovascular Research Initiative (an initiative of the Dutch Heart Foundation), the Brain Foundation Netherlands, Medtronic, Health-Holland, and Top Sector Life Sciences. The study received additional unrestricted funding from Stryker European Operations. Dr. Roos and Dr. Majoie are shareholders of Nico Lab.

Six pregnancy-related complications increase a woman’s risk of developing risk factors for cardiovascular disease (CVD) and subsequently developing CVD, the American Heart Association says in a new scientific statement.

They are hypertensive disorders of pregnancy, preterm delivery, gestational diabetes, small-for-gestational-age (SGA) delivery, placental abruption (abruptio placentae), and pregnancy loss.

A history of any of these adverse pregnancy outcomes should prompt “more vigorous primordial prevention of CVD risk factors and primary prevention of CVD,” the writing group says.

“Adverse pregnancy outcomes are linked to women having hypertension, diabetes, abnormal cholesterol, and cardiovascular disease events, including heart attack and stroke, long after their pregnancies,” Nisha I. Parikh, MD, MPH, chair of the writing group, said in a news release.

Adverse pregnancy outcomes can be a “powerful window” into CVD prevention “if women and their health care professionals harness the knowledge and use it for health improvement,” said Dr. Parikh, associate professor of medicine in the cardiovascular division at the University of California, San Francisco.

The statement was published online March 29 in Circulation.

For the scientific statement, the writing group reviewed the latest scientific literature on adverse pregnancy outcomes and CVD risk. 

The evidence in the literature linking adverse pregnancy outcomes to later CVD is “consistent over many years and confirmed in nearly every study we examined,” Dr. Parikh said. Among their key findings:

• Gestational hypertension is associated with an increased risk of CVD later in life by 67% and the odds of stroke by 83%. Moderate and severe  is associated with a more than twofold increase in the risk for CVD.
• Gestational diabetes is associated with an increase in the risk for CVD by 68% and the risk of developing  after pregnancy by 10-fold.
• Preterm delivery (before 37 weeks) is associated with double the risk of developing CVD and is strongly associated with later heart disease, stroke, and CVD.
• Placental abruption is associated with an 82% increased risk for CVD.
• Stillbirth is associated with about double the risk for CVD.

“This statement should inform future prevention guidelines in terms of the important factors to consider for determining women’s risk for heart diseases and stroke,” Dr. Parikh added.

The statement emphasizes the importance of recognizing these adverse pregnancy outcomes when evaluating CVD risk in women but notes that their value in reclassifying CVD risk may not be established.

It highlights the importance of adopting a heart-healthy diet and increasing physical activity among women with any of these pregnancy-related complications, starting right after childbirth and continuing across the life span to decrease CVD risk.

Lactation and breastfeeding may lower a woman’s later cardiometabolic risk, the writing group notes.
 

‘Golden year of opportunity’

The statement highlights several opportunities to improve transition of care for women with adverse pregnancy outcomes and to implement strategies to reduce their long-term CVD risk.

One strategy is longer postpartum follow-up care, sometimes referred to as the “fourth trimester,” to screen for CVD risk factors and provide CVD prevention counseling.

Another strategy involves improving the transfer of health information between ob/gyns and primary care physicians to eliminate inconsistencies in electronic health record documentation, which should improve patient care.

A third strategy is obtaining a short and targeted health history for each woman to confirm if she has any of the six pregnancy-related complications.

“If a woman has had any of these adverse pregnancy outcomes, consider close blood pressure monitoring, type 2 diabetes and lipid screening, and more aggressive risk factor modification and CVD prevention recommendations,” Dr. Parikh advised.

“Our data [lend] support to the prior AHA recommendation that these important adverse pregnancy outcomes should be ‘risk enhancers’ to guide consideration for statin therapy aimed at CVD prevention in women,” Dr. Parikh added.

In a commentary in Circulation, Eliza C. Miller, MD, assistant professor of neurology at Columbia University, New York, notes that pregnancy and the postpartum period are a critical time window in a woman’s life to identify CVD risk and improve a woman’s health trajectory.

“The so-called ‘Golden Hour’ for conditions such as sepsis and acute stroke refers to a critical time window for early recognition and treatment, when we can change a patient’s clinical trajectory and prevent severe morbidity and mortality,” writes Dr. Miller.

“Pregnancy and the postpartum period can be considered a ‘Golden Year’ in a woman’s life, offering a rare opportunity for clinicians to identify young women at risk and work with them to improve their cardiovascular health trajectories,” she notes.

Six pregnancy-related complications increase a woman’s risk of developing risk factors for cardiovascular disease (CVD) and subsequently developing CVD, the American Heart Association says in a new scientific statement.

They are hypertensive disorders of pregnancy, preterm delivery, gestational diabetes, small-for-gestational-age (SGA) delivery, placental abruption (abruptio placentae), and pregnancy loss.

A history of any of these adverse pregnancy outcomes should prompt “more vigorous primordial prevention of CVD risk factors and primary prevention of CVD,” the writing group says.

“Adverse pregnancy outcomes are linked to women having hypertension, diabetes, abnormal cholesterol, and cardiovascular disease events, including heart attack and stroke, long after their pregnancies,” Nisha I. Parikh, MD, MPH, chair of the writing group, said in a news release.

Adverse pregnancy outcomes can be a “powerful window” into CVD prevention “if women and their health care professionals harness the knowledge and use it for health improvement,” said Dr. Parikh, associate professor of medicine in the cardiovascular division at the University of California, San Francisco.

The statement was published online March 29 in Circulation.

For the scientific statement, the writing group reviewed the latest scientific literature on adverse pregnancy outcomes and CVD risk. 

The evidence in the literature linking adverse pregnancy outcomes to later CVD is “consistent over many years and confirmed in nearly every study we examined,” Dr. Parikh said. Among their key findings:

• Gestational hypertension is associated with an increased risk of CVD later in life by 67% and the odds of stroke by 83%. Moderate and severe  is associated with a more than twofold increase in the risk for CVD.
• Gestational diabetes is associated with an increase in the risk for CVD by 68% and the risk of developing  after pregnancy by 10-fold.
• Preterm delivery (before 37 weeks) is associated with double the risk of developing CVD and is strongly associated with later heart disease, stroke, and CVD.
• Placental abruption is associated with an 82% increased risk for CVD.
• Stillbirth is associated with about double the risk for CVD.

“This statement should inform future prevention guidelines in terms of the important factors to consider for determining women’s risk for heart diseases and stroke,” Dr. Parikh added.

The statement emphasizes the importance of recognizing these adverse pregnancy outcomes when evaluating CVD risk in women but notes that their value in reclassifying CVD risk may not be established.

It highlights the importance of adopting a heart-healthy diet and increasing physical activity among women with any of these pregnancy-related complications, starting right after childbirth and continuing across the life span to decrease CVD risk.

Lactation and breastfeeding may lower a woman’s later cardiometabolic risk, the writing group notes.
 

‘Golden year of opportunity’

The statement highlights several opportunities to improve transition of care for women with adverse pregnancy outcomes and to implement strategies to reduce their long-term CVD risk.

One strategy is longer postpartum follow-up care, sometimes referred to as the “fourth trimester,” to screen for CVD risk factors and provide CVD prevention counseling.

Another strategy involves improving the transfer of health information between ob/gyns and primary care physicians to eliminate inconsistencies in electronic health record documentation, which should improve patient care.

A third strategy is obtaining a short and targeted health history for each woman to confirm if she has any of the six pregnancy-related complications.

“If a woman has had any of these adverse pregnancy outcomes, consider close blood pressure monitoring, type 2 diabetes and lipid screening, and more aggressive risk factor modification and CVD prevention recommendations,” Dr. Parikh advised.

“Our data [lend] support to the prior AHA recommendation that these important adverse pregnancy outcomes should be ‘risk enhancers’ to guide consideration for statin therapy aimed at CVD prevention in women,” Dr. Parikh added.

In a commentary in Circulation, Eliza C. Miller, MD, assistant professor of neurology at Columbia University, New York, notes that pregnancy and the postpartum period are a critical time window in a woman’s life to identify CVD risk and improve a woman’s health trajectory.
