New Blood Test for Large Vessel Stroke Could Be a ‘Game Changer’
When combined with clinical scores, a “game-changing” blood test can expedite the diagnosis and treatment of large vessel occlusion (LVO) stroke, potentially saving many lives, new data suggested.
Using cutoff levels of two blood biomarkers, glial fibrillary acidic protein (GFAP; 213 pg/mL) and D-dimer (600 ng/mL), and the field assessment stroke triage for emergency destination (FAST-ED) (score, > 2), investigators were able to detect LVOs with 81% sensitivity and 93% specificity less than 6 hours from the onset of symptoms.
GFAP has previously been linked to brain bleeds and traumatic brain injury.
The test also ruled out all patients with brain bleeds, and investigators noted that it could also be used to detect intracerebral hemorrhage.
“We have developed a game-changing, accessible tool that could help ensure that more people suffering from stroke are in the right place at the right time to receive critical, life-restoring care,” senior author Joshua Bernstock, MD, PhD, MPH, a clinical fellow in the department of neurosurgery at Brigham and Women’s Hospital in Boston, said in a press release.
The findings were published online on May 17 in Stroke: Vascular and Interventional Neurology.
Early Identification Crucial
Acute LVO stroke is one of the most treatable stroke types because of the availability of endovascular thrombectomy (EVT). However, EVT requires specialized equipment and teams that represent a small subset of accredited stroke centers and an even smaller subset of emergency medical facilities, so early identification of LVO is crucial, the investigators noted.
Dr. Bernstock and his team developed the TIME trial to assess the sensitivity and specificity of the blood biomarkers and scale cutoff values for identifying LVO vs non-LVO stroke.
As part of the observational prospective cohort trial, investigators included consecutive patients admitted to the Brandon Regional Hospital Emergency Department in Brandon, Florida, between May 2021 and August 2022 if they were referred for a suspected stroke and the time from symptom onset was under 18 hours.
Patients were excluded if they received thrombolytic therapy before blood was collected or if it was anticipated that blood collection would be difficult.
Investigators gathered information on patients’ clinical data, hematology results, time since last known well, and imaging findings to construct a clinical diagnosis (LVO, non-LVO, ischemic stroke, hemorrhagic stroke, or transient ischemic attack [TIA]).
In addition to the National Institutes of Health Stroke Scale, patients were assessed with the FAST-ED, the Rapid Arterial oCclusion Evaluation (RACE), the Cincinnati Stroke Triage Assessment Tool, and the Emergency Medical Stroke Assessment.
Of 323 patients in the final study sample, 29 (9%) had LVO ischemic stroke, and 48 (15%) had non-LVO ischemic stroke. Another 13 (4%) had hemorrhagic stroke, 12 had TIA (3.7%), and the largest proportion of patients had stroke mimic (n = 220; 68%), which included encephalopathy, hyperglycemia, hypertensive emergency, migraine, posterior reversible encephalopathy syndrome, and undetermined.
The Case for Biomarkers
When investigators looked at those with LVO ischemic stroke, they found the concentration of plasma D-dimer was significantly higher than that in patients with non-LVO suspected stroke (LVO suspected stroke, 1213 ng/mL; interquartile range [IQR], 733-1609 vs non-LVO suspected stroke, 617 ng/mL; IQR, 377-1345; P < .001).
In addition, GFAP was significantly increased in the plasma of patients with hemorrhagic stroke vs all other patients with suspected stroke (hemorrhagic stroke, 1464 pg/mL; IQR, 292-2580 vs nonhemorrhagic suspected stroke, 48 pg/mL; IQR, 12-98; P < .005).
Combinations of the blood biomarkers with the scales FAST-ED or RACE showed the best performance for LVO detection, with a specificity of 94% (for either scale combination) and a sensitivity of 71% for both scales.
When investigators analyzed data for just those patients identified within 6 hours of symptom onset, the combination of biomarkers plus FAST-ED resulted in a specificity of 93% and a sensitivity of 81%.
Given that clinical stroke scales in patients with hemorrhagic stroke frequently suggest LVO and that these patients are not candidates for EVT, a tool capable of ruling out hemorrhage and identifying only nonhemorrhagic ischemic LVO is essential, the investigators noted.
“In stroke care, time is brain,” Dr. Bernstock said. “The sooner a patient is put on the right care pathway, the better they are going to do. Whether that means ruling out bleeds or ruling in something that needs an intervention, being able to do this in a prehospital setting with the technology that we built is going to be truly transformative.”
The study was funded by the Innovate UK grant and private funding. Dr. Bernstock has positions and equity in Pockit Diagnostics Ltd. and Treovir Inc. and is on the boards of Centile Bio and NeuroX1. Other disclosures are noted in the original article.

FROM STROKE: VASCULAR AND INTERVENTIONAL NEUROLOGY
Why Are We Undertreating So Many Pulmonary Embolisms?
LONG BEACH, CALIFORNIA — A small fraction of patients with pulmonary embolism (PE) who are eligible for advanced therapies are actually getting them, reported investigators who conducted a big data analysis.
“Advanced PE therapy seems to be vulnerable to disparate use, and perhaps underuse,” Sahil Parikh, MD, a cardiovascular interventionalist at the Columbia University Medical Center in New York, said when he presented results from the REAL-PE study at the Society for Cardiovascular Angiography and Interventions (SCAI) 2024 Scientific Sessions.
The underuse of advanced PE therapies is “the controversy,” Dr. Parikh said after his presentation. “It remains unclear what the role of invasive therapy is in the management of so-called high-intermediate–risk people. There isn’t a Class 1 guideline recommendation, and there is a very rapidly evolving trend that we’re increasingly treating these patients invasively,” he said.
“However, if you come to these meetings [such as SCAI], you might think everyone is getting one of these devices, but these data show that’s not the case,” Dr. Parikh said.
The analysis mined deidentified data from Truveta, a collective of health systems that provides regulatory-grade electronic health record data for research.
The researchers accessed data on patients treated with ultrasound-assisted catheter-directed thrombolysis or mechanical thrombectomy, identified from claims codes. Patient characteristics — age, race, ethnicity, sex, comorbidities, and diagnoses — were also accessed for the analysis. Earlier results were published in the January issue of the Journal of the Society for Cardiovascular Angioplasty Interventions.
Less Intervention for Black Patients and Women
White patients were more likely to receive advanced therapy than were Black patients (0.5% vs 0.37%; P = .000), Dr. Parikh reported, and women were less likely to receive advanced therapy than were men (0.41% vs 0.55%; P = .000).
The only discernable differences in outcomes were in major bleeding events in the 7 days after the procedure, which affected more White patients than it did Black patients (13.9% vs 9.3%) and affected more women than it did men (16.6% vs 11.1%).
What’s noteworthy about this study is that it demonstrates the potential of advanced data analytics to identify disparities in care and outcomes, Dr. Parikh said during his presentation. “These analyses provide a means of evaluating disparities in real clinical practice, both in the area of PE and otherwise, and may also be used for real-time monitoring of clinical decision-making and decisional support,” he said. “We do think that both novel and established therapies can benefit equally from similar types of analyses.”
Big Data Signaling Disparities
“That’s where these data are helpful,” Dr. Parikh explained. They provide “a real snapshot of how many procedures are being performed and in what kinds of patients. The low number of patients getting the procedure would suggest that there are probably more patients who would be eligible for treatment based on some of the emerging consensus documents, and they’re not receiving them.”
The data are “hypotheses generating,” Dr. Parikh said in an interview. “These hypotheses have to be evaluated further in more granular databases.”
REAL-PE is also a “clarion call” for clinical trials of investigative devices going forward, he said. “In those trials, we need to endeavor to enroll enough women and men, minority and nonminority patients so that we can make meaningful assessments of differences in efficacy and safety.”
This study is “real proof that big data can be used to provide information on outcomes for patients in a very rapid manner; that’s really exciting,” said Ethan Korngold, MD, chair of structural and interventional cardiology at the Providence Health Institute in Portland, Oregon. “This is an area of great research with great innovation, and it’s proof that, with these type of techniques using artificial intelligence and big data, we can generate data quickly on how we’re doing and what kind of patients we’re reaching.”
Findings like these may also help identify sources of the disparities, Dr. Korngold added.
“This shows we need to be reaching every patient with advanced therapies,” he said. “Different hospitals have different capabilities and different expertise in this area and they reach different patient populations. A lot of the difference in utilization stems from this fact,” he said.
“It just underscores the fact that we need to standardize our treatment approaches, and then we need to reach every person who’s suffering from this disease,” Dr. Korngold said.

Who Benefits From Omega-3/Fish Oil Supplements?
I’d like to talk with you about a recent report in the British Medical Journal on the regular use of omega-3 fish oil supplements and the course of cardiovascular disease (CVD).
This is an observational study from the large-scale UK Biobank. The authors divided the participants into those with and those without CVD. In participants without CVD at baseline, those using fish oil supplements regularly had an increased incidence of both atrial fibrillation (AF) and stroke, whereas those with prevalent CVD had a reduction in the progression to major adverse cardiovascular events, which offset any increase in the risk for AF.
Observational studies of omega-3 supplements have potential limitations and confounding, and correlation in these studies does not prove causation. What do the randomized clinical trials of omega-3 supplements show? At least seven randomized trials have looked at AF. A meta-analysis published in Circulation in 2021 showed a dose-response relationship. In trials testing > 1 g/d of marine omega-3 fatty acids, there was close to a 50% overall increase in risk for AF. In studies testing lower doses, there was a very modest 12% increase and a significant dose-response gradient.
For the relationship between omega-3 supplements and major cardiovascular events, at least 15 individual randomized trials have been conducted. There actually have been more meta-analyses of these randomized trials than individual trials. The meta-analyses tend to show a significant reduction of coronary events with omega-3 supplementation, but no reduction in stroke. This is true in both primary and secondary prevention trials.
The one exception to this finding is the REDUCE-IT trial testing high-dose eicosapentaenoic acid (EPA) (4 g/day of icosapent ethyl), and there was a 25%-30% reduction in both cardiovascular events and stroke. But there has been some criticism of the mineral oil placebo used in the REDUCE-IT trial that it may have had adverse effects on biomarkers and might have interfered with the absorption of statins in the placebo group. So, it will be important to have a replication trial of the high-dose EPA, findings in a trial using an inert placebo such as corn oil.
What should be done in the meantime? It’s important to think about prescription omega-3s vs over-the-counter fish oil. The US Food and Drug Administration (FDA) has approved prescription omega-3 medications for several indications, including severely elevated triglyceride levels (> 500 mg/dL). In the REDUCE-IT trial, those who had moderate elevations of triglycerides (≥ 150 mg/dL) or prevalent CVD or diabetes, plus two additional risk factors, were also considered to have indications based on the FDA labeling for icosapent ethyl.
What about patients who don’t meet these criteria for prescription omega-3s? In the VITAL trial (the large-scale primary prevention trial), there was a similar reduction in coronary events but no effect on stroke. Those who seemed to benefit the most in terms of at least 40% reduction in coronary events were participants who had low fish consumption at baseline, had two or more risk factors for cardiovascular disease, or were African American.
There is a national recommendation for one to two servings of fish per week. For those planning to take fish oil, it’s important to use reputable sources of the supplement, and check the bottle for a quality control seal. It’s also really important to avoid megadoses of fish oil, because high doses have been linked to an increased risk for AF and bleeding.

What should be done in the meantime? It’s important to think about prescription omega-3s vs over-the-counter fish oil. The US Food and Drug Administration (FDA) has approved prescription omega-3 medications for several indications, including severely elevated triglyceride levels (> 500 mg/dL). In the REDUCE-IT trial, those who had moderate elevations of triglycerides (≥ 150 mg/dL) or prevalent CVD or diabetes, plus two additional risk factors, were also considered to have indications based on the FDA labeling for icosapent ethyl.
What about patients who don’t meet these criteria for prescription omega-3s? In the VITAL trial (the large-scale primary prevention trial), there was a similar reduction in coronary events but no effect on stroke. Those who seemed to benefit the most in terms of at least 40% reduction in coronary events were participants who had low fish consumption at baseline, had two or more risk factors for cardiovascular disease, or were African American.
There is a national recommendation for one to two servings of fish per week. For those planning to take fish oil, it’s important to use reputable sources of the supplement, and check the bottle for a quality control seal. It’s also really important to avoid megadoses of fish oil, because high doses have been linked to an increased risk for AF and bleeding.

I’d like to talk with you about a recent report in the British Medical Journal on the regular use of omega-3 fish oil supplements and the course of cardiovascular disease (CVD).
This is an observational study from the large-scale UK Biobank. The authors divided the participants into those with and those without CVD. In participants without CVD at baseline, those using fish oil supplements regularly had an increased incidence of both atrial fibrillation (AF) and stroke, whereas those with prevalent CVD had a reduction in the progression to major adverse cardiovascular events, which offset any increase in the risk for AF.
Observational studies of omega-3 supplements have potential limitations and confounding, and correlation in these studies does not prove causation. What do the randomized clinical trials of omega-3 supplements show? At least seven randomized trials have looked at AF. A meta-analysis published in Circulation in 2021 showed a dose-response relationship. In trials testing > 1 g/d of marine omega-3 fatty acids, there was close to a 50% overall increase in risk for AF. In studies testing lower doses, there was a very modest 12% increase and a significant dose-response gradient.
For the relationship between omega-3 supplements and major cardiovascular events, at least 15 individual randomized trials have been conducted. There actually have been more meta-analyses of these randomized trials than individual trials. The meta-analyses tend to show a significant reduction of coronary events with omega-3 supplementation, but no reduction in stroke. This is true in both primary and secondary prevention trials.
The one exception to this finding is the REDUCE-IT trial testing high-dose eicosapentaenoic acid (EPA) (4 g/day of icosapent ethyl), and there was a 25%-30% reduction in both cardiovascular events and stroke. But there has been some criticism of the mineral oil placebo used in the REDUCE-IT trial that it may have had adverse effects on biomarkers and might have interfered with the absorption of statins in the placebo group. So, it will be important to have a replication trial of the high-dose EPA, findings in a trial using an inert placebo such as corn oil.

Is Semaglutide the ‘New Statin’? Not So Fast
There has been much hyperbole since the presentation of results from the SELECT cardiovascular outcomes trial (CVOT) at this year’s European Congress on Obesity, which led many to herald semaglutide as the “new statin.”
In the SELECT CVOT, participants with overweight or obesity (body mass index [BMI] ≥ 27), established cardiovascular disease (CVD), and no history of type 2 diabetes were administered the injectable glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) at a 2.4-mg dose weekly. Treatment resulted in a significant 20% relative risk reduction in major adverse CV events (a composite endpoint comprising CV death, nonfatal myocardial infarction, or nonfatal stroke). Importantly, SELECT was a trial on secondary prevention of CVD.
The CV benefits of semaglutide were notably independent of baseline weight or amount of weight lost. This suggests that the underlying driver of improved CV outcomes with semaglutide extends beyond simple reduction in obesity and perhaps indicates a direct effect on vasculature and reduction in atherosclerosis, although this remains unproven.
Not All Risk Reduction Is Equal
Much of the sensationalist coverage in the lay press focused on the 20% relative risk reduction figure. This endpoint is often more impressive and headline-grabbing than the absolute risk reduction, which provides a clearer view of a treatment’s real-world impact.
In SELECT, the absolute risk reduction was 1.5 percentage points, which translated into a number needed to treat (NNT) of 67 over 34 months to prevent one primary outcome of a major adverse CV event.
Lower NNTs suggest more effective treatments because fewer people need to be treated to prevent one clinical event, such as the major adverse CV events used in SELECT.
Semaglutide vs Statins
How does the clinical effectiveness observed in the SELECT trial compare with that observed in statin trials when it comes to the secondary prevention of CVD?
The seminal 4S study published in 1994 explored the impact of simvastatin on all-cause mortality among people with previous myocardial infarction or angina and hyperlipidemia (mean baseline BMI, 26). After 5.4 years of follow-up, the trial was stopped early owing to a 3.3-percentage point absolute risk reduction in all-cause mortality (NNT, 30; relative risk reduction, 28%). The NNT to prevent one death from CV causes was 31, and the NNT to prevent one major coronary event was lower, at 15.
Other statin secondary prevention trials, such as the LIPID and MIRACL studies, demonstrated similarly low NNTs.
So, you can see that the NNTs for statins in secondary prevention are much lower than with semaglutide in SELECT. Furthermore, the benefits of semaglutide in preventing CVD in people living with overweight/obesity have yet to be elucidated.
In contrast, we already have published evidence showing the benefits of statins in the primary prevention of CVD, albeit with higher and more variable NNTs than in the statin secondary prevention studies.
The benefits of statins are also postulated to extend beyond their impact on lowering low-density lipoprotein cholesterol. Statins have been suggested to have anti-inflammatory and plaque-stabilizing effects, among other pleiotropic benefits.
We also currently lack evidence for the cost-effectiveness of semaglutide for CV risk reduction. Assessing economic viability and use in health care systems, such as the UK’s National Health Service, involves comparing the cost of semaglutide against the health care savings from prevented CV events. Health economic studies are vital to determine whether the benefits justify the expense. In contrast, the cost-effectiveness of statins is well established, particularly for high-risk individuals.
Advantages of GLP-1s Should Not Be Overlooked
Of course, statins don’t provide the significant weight loss benefits of semaglutide.
Additional data from SELECT presented at the 2024 European Congress on Obesity demonstrated that participants lost a mean of 10.2% body weight and 7.7 cm from their waist circumference after 4 years. Moreover, after 2 years, 12% of individuals randomized to semaglutide had returned to a normal BMI, and nearly half were no longer living with obesity.
Although the CV benefits of semaglutide were independent of weight reduction, this level of weight loss is clinically meaningful and will reduce the risk of many other cardiometabolic conditions including type 2 diabetes, metabolic dysfunction–associated steatotic liver disease, and obstructive sleep apnea/hypopnea syndrome, as well as improve low mood, depression, and overall quality of life. Additionally, obesity is now a risk factor for 13 different types of cancer, including bowel, breast, and pancreatic cancer, so facilitating a return to a healthier body weight will also mitigate future risk for cancer.
Sticking With Our Cornerstone Therapy, For Now
In conclusion, I do not believe that semaglutide is the “new statin.” Statins are the cornerstone of primary and secondary prevention of CVD in a wide range of comorbidities, as evidenced in multiple large and high-quality trials dating back over 30 years.
However, there is no doubt that the GLP-1 receptor agonist class is the most significant therapeutic advance for the management of obesity and comorbidities to date.
The SELECT CVOT data uniquely position semaglutide as a secondary CVD prevention agent on top of guideline-driven management for people living with overweight/obesity and established CVD. Additionally, the clinically meaningful weight loss achieved with semaglutide will impact the risk of developing many other cardiometabolic conditions, as well as improve mental health and overall quality of life.

Study Finds Mace Risk Remains High in Patients with Psoriasis, Dyslipidemia
Over a period of 5 years, the, even after adjusting for covariates, results from a large retrospective study showed.
“It is well-established that psoriasis is an independent risk factor for the development of MACE, with cardiometabolic risk factors being more prevalent and incident among patients with psoriasis,” the study’s first author Ana Ormaza Vera, MD, a dermatology research fellow at Eastern Virginia Medical School, Norfolk, said in an interview after the annual meeting of the Society for Investigational Dermatology, where the study was presented during a late-breaking abstract session.
Current guidelines from the joint American Academy of Dermatology/National Psoriasis Foundation and the American Academy of Cardiology/American Heart Association Task Force recommend statins, a lipid-lowering and anti-inflammatory therapy, “for patients with psoriasis who have additional risk-enhancing factors, similar to recommendations made for the general population without psoriasis,” she noted. But how the incidence of MACE differs between patients with and without psoriasis while on statin therapy “has not been explored in real-world settings,” she added.
To address this question, the researchers used real-world data from the TriNetX health research network to identify individuals aged 18-90 years with a diagnosis of both psoriasis and lipid disorders who were undergoing treatment with statins. Those with a prior history of MACE were excluded from the analysis. Patients with lipid disorders on statin therapy, but without psoriatic disease, were matched 1:1 by age, sex, race, ethnicity, common risk factors for MACE, and medications shown to reduce MACE risk. The researchers then assessed the cohorts 5 years following their first statin prescription and used the TriNetX analytics tool to calculate the odds ratio (OR) with 95% CI to evaluate the likelihood of MACE in the presence of statin therapy.
Dr. Ormaza Vera and colleagues identified 20,660 patients with psoriasis and 2,768,429 patients without psoriasis who met the criteria for analysis. After propensity score matching, each cohort included 20,660 patients with a mean age of 60 years. During the 5-year observation period, 2725 patients in the psoriasis cohort experienced MACE compared with 2203 patients in the non-psoriasis cohort (OR, 1.40; 95% CI, 1.317-1.488).
“This was an unexpected outcome that challenges the current understanding and highlights the need for further research into tailored treatments for cardiovascular risk in psoriasis patients,” Dr. Ormaza Vera told this news organization.
She acknowledged certain limitations of the study, including its retrospective design, the inherent limitations of an observational study, and the use of electronic medical record data.
Lawrence J. Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”
The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

Green, MD, clinical professor of dermatology, George Washington University, Washington, who was asked to comment on the study results, said that the findings imply that there is more than statin use alone to protect someone with psoriasis from having an increased risk for MACE. “This is not really surprising because statin use alone is only part of a prevention strategy in someone with psoriasis who usually has multiple comorbidities,” Dr. Green said. “On the other hand, the study only went out for 5 years and cardiovascular disease is a long accumulating process, so it could also be too early to demonstrate MACE prevention.”
The study was funded by a grant from the American Skin Association. Dr. Ormaza Vera and her coauthors reported having no relevant disclosures. Dr. Green disclosed that he is a speaker, consultant, or investigator for many pharmaceutical companies.

Arterial Stiffness May Predict Risk for Glaucoma
TOPLINE:
Arterial stiffness increases the risk for developing glaucoma, a new study found.
METHODOLOGY:
- To study the link between arterial stiffness and glaucoma, the researchers evaluated 4713 individuals (mean age, 66 years; 58% men) without the eye condition at baseline between April 2011 and November 2012.
- They assessed arterial stiffness by measuring aortic pulse wave velocity, estimated carotid-femoral pulse wave velocity, and aortic pulse pressure.
- The primary outcome was incident glaucoma, identified from prescriptions for eye drops or hospital records.
TAKEAWAY:
- Overall, 301 people in the study developed glaucoma over a mean follow-up period of 10.5 years.
- Incident glaucoma increased across all quartiles of arterial stiffness, with the highest risk observed in the fourth quartile for aortic pulse wave velocity (HR, 2.41; 95% CI, 1.36-4.26), estimated carotid-femoral pulse wave velocity (HR, 2.29; 95% CI, 1.27-4.13), and aortic pulse pressure (HR, 1.76; 95% CI, 1.10-2.82).
- The cumulative incidence of glaucoma rose with increases in arterial stiffness. This trend was statistically significant for both aortic and estimated pulse wave velocity (P < .0001) and aortic pulse pressure (P = .02).
IN PRACTICE:
“Arterial stiffness…which can be easily and accurately measured, could be used as a tool in clinical practice [as part of routine blood pressure measurement] to help identify people at risk of glaucoma and as a therapeutic target to prevent glaucoma progression,” the authors wrote.
SOURCE:
This study was led by Angela L. Beros, MPH, of the School of Population Health at the University of Auckland, Auckland, New Zealand, and published online in the American Journal of Ophthalmology.
LIMITATIONS:
The cohort study did not clinically assess for glaucoma, potentially leading to the inclusion of individuals with the condition. Not all participants with incident glaucoma, particularly those unaware of their diagnosis, may have been identified. Intraocular pressure and central corneal thickness, which are common risk factors for glaucoma, were not included in the multivariate analysis.
DISCLOSURES:
The study did not receive any funding. The authors declared no conflicts of interest.

Progestin-Only IUDs Linked to 22% Lower Ischemic Stroke Risk
Women who used levonorgestrel-releasing intrauterine devices (LG-IUDs) were 22% less likely to have a stroke than those who did not use hormonal contraception, new research suggested.
The Danish study, which included 1.7 million women, also showed no increased risk for intracerebral hemorrhage for those using the IUDs.
“The finding raises the question of whether levonorgestrel, in addition to its contraceptive properties, could have the potential to prevent (ischemic stroke),” wrote corresponding author Tom Skyhøj Olsen, MD, PhD, of Bispebjerg University Hospital, Copenhagen, Denmark, and coauthors.
The research was published online on May 16, 2024, in the journal Stroke.
A Big-Picture Look
Commonly used combined hormonal contraceptives that contain both progestins and ethinylestradiol are linked to an increased risk for ischemic stroke. Previous research suggested that progestin-only options, including LG-IUDs, are not associated with elevated risk and may even lower the risk. The IUDs had also been previously associated with lower risk for thromboembolism.
The new study was a large-scale investigation of all reproductive-age women in Denmark that compared stroke risk in those who used the progestin-only IUDs with those who didn’t use hormonal contraception. It also examined the risk for intracerebral hemorrhage, which had not been previously studied.
The historic cohort study drew on several large national databases in Denmark, including the Danish Stroke Registry, to evaluate the interplay between IUD contraception, stroke, and intracerebral hemorrhage. The study looked back at data collected on all nonpregnant Danish women aged 18-49 years who lived in Denmark for some or all of the period between 2004 and 2021.
Mean age of the 1.7 million women in the study was 30 years, and the mean follow-up period was about 7 years. More than 364,700 participants used LG-IUDs.
During the study period, 2916 women had an ischemic stroke, and 367 experienced intracerebral hemorrhage.
Among IUD users, the incidence of stroke was 19.2 per 100,000 person years. For women who didn’t use contraception, the rate was 25.2.
Overall, those who used an IUD had a 22% lower risk for ischemic stroke than those who didn’t (incidence rate ratio [IRR], 0.78; 95% CI, 0.70-0.88).
The incidence of brain bleeds was similar in both groups.
Does Age Matter?
The incidence of stroke did not differ significantly between the three age groups analyzed in the study: Women aged 18-29 years, 30-39 years, and 40-49 years. Incidence rates of intracerebral hemorrhage were similar between age groups 30-39 years and 40-49 years, but the risk was higher for those aged 18-29 years than for those aged 40-49 years (IRR, 4.49; 95% CI, 1.65-12.19).
The researchers urged caution in interpreting the apparent higher risk for brain bleeds in younger women, noting that the overall number of events was low, resulting in wide CIs.
Investigators also found that women who moved to Denmark from non-Western countries had a significantly lower stroke rate than native Danes. Incidence rates of intracerebral hemorrhage were not affected by country of origin.
The research team noted that they had only indirect information about women’s stroke risk factors including diabetes, high blood pressure, and migraine and had no information about smoking, alcohol consumption, and body mass index.
“Regarding a possible potential for stroke prevention, our study cannot stand alone and requires confirmation in further research. Even though the incidence rate for [ischemic stroke] and [intracerebral hemorrhage] did not significantly change after adjustment for various factors, bias…cannot be fully ruled out,” the researchers wrote.
The study was funded by the Aase og Ejnar Danielsens Fond and Familien Hede Nielsens Fond. The authors reported no relevant financial relationships.

Calcium and CV Risk: Are Supplements and Vitamin D to Blame?
This transcript has been edited for clarity.
Tricia Ward: Hi. I’m Tricia Ward, from theheart.org/Medscape Cardiology. I’m joined today by Dr Matthew Budoff. He is professor of medicine at UCLA and the endowed chair of preventive cardiology at the Lundquist Institute. Welcome, Dr Budoff.
Matthew J. Budoff, MD: Thank you.
Dietary Calcium vs Coronary Calcium
Ms. Ward: The reason I wanted to talk to you today is because there have been some recent studies linking calcium supplements to an increased risk for cardiovascular disease. I’m old enough to remember when we used to tell people that dietary calcium and coronary calcium weren’t connected and weren’t the same. Were we wrong?
Dr. Budoff: I think there’s a large amount of mixed data out there still. The US Preventive Services Task Force looked into this a number of years ago and said there’s no association between calcium supplementation and increased risk for cardiovascular disease.
As you mentioned, there are a couple of newer studies that point us toward a relationship. I think that we still have a little bit of a mixed bag, but we need to dive a little deeper into that to figure out what’s going on.
Ms. Ward: Does it appear to be connected to calcium in the form of supplements vs calcium from foods?
Dr. Budoff: We looked very carefully at dietary calcium in the MESA study, the multiethnic study of atherosclerosis. There is no relationship between dietary calcium intake and coronary calcium or cardiovascular events. We’re talking mostly about supplements now when we talk about this increased risk that we’re seeing.
Does Vitamin D Exacerbate Risk?
Ms. Ward: Because it’s seen with supplements, is that likely because that’s a much higher concentration of calcium coming in or do you think it’s something inherent in its being in the form of a supplement?
Dr. Budoff: I think there are two things. One, it’s definitely a higher concentration all at once. You get many more milligrams at a time when you take a supplement than if you had a high-calcium food or drink.
Also, most supplements have vitamin D as well. I think vitamin D and calcium work synergistically. When you give them both together simultaneously, I think that may have more of a potentiating effect that might exacerbate any potential risk.
Ms. Ward: Is there any reason to think there might be a difference in type of calcium supplement? I always think of the chalky tablet form vs calcium chews.
Dr. Budoff: I’m not aware of a difference in the supplement type. I think the vitamin D issue is a big problem because we all have patients who take thousands of units of vitamin D — just crazy numbers. People advocate really high numbers and that stays in the system.
Personally, I think part of the explanation is that with very high levels of vitamin D on top of calcium supplementation, you now absorb it better. You now get it into the bone, but maybe also into the coronary arteries. If you’re very high in vitamin D and then are taking a large calcium supplement, it might be the calcium/vitamin D combination that’s giving us some trouble. I think people on vitamin D supplements really need to watch their levels and not get supratherapeutic.
Ms. Ward: With the vitamin D?
Dr. Budoff: With the vitamin D.
Diabetes and Renal Function
Ms. Ward: In some of the studies, there seems to be a higher risk in patients with diabetes. Is there any reason why that would be?
Dr. Budoff: I can’t think of a reason exactly why with diabetes per se, except for renal disease. Patients with diabetes have more intrinsic renal disease, proteinuria, and even a reduced eGFR. We’ve seen that the kidney is very strongly tied to this. We have a very strong relationship, in work I’ve done a decade ago now, showing that calcium supplementation (in the form of phosphate binders) in patients on dialysis or with advanced renal disease is linked to much higher coronary calcium progression.
We did prospective, randomized trials showing that calcium intake as binders to reduce phosphorus led to more coronary calcium. We always thought that was just relegated to the renal population, and there might be an overlap here with the diabetes and more renal disease. I have a feeling that it has to do with more of that. It might be regulation of parathyroid hormone as well, which might be more abnormal in patients with diabetes.
Avoid Supratherapeutic Vitamin D Levels
Ms. Ward:: What are you telling your patients?
Dr. Budoff: I tell patients with normal kidney function that the bone will modulate 99.9% of the calcium uptake. If they have osteopenia or osteoporosis, regardless of their calcium score, I’m very comfortable putting them on supplements.
I’m a little more cautious with the vitamin D levels, and I keep an eye on that and regulate how much vitamin D they get based on their levels. I get them into the normal range, but I don’t want them supratherapeutic. You can even follow their calcium score. Again, we’ve shown that if you’re taking too much calcium, your calcium score will go up. I can just check it again in a couple of years to make sure that it’s safe.
Ms. Ward:: In terms of vitamin D levels, when you’re saying “supratherapeutic,” what levels do you consider a safe amount to take?
Dr. Budoff: I’d like them under 100 ng/mL as far as their upper level. Normal is around 70 ng/mL at most labs. I try to keep them in the normal range. I don’t even want them to be high-normal if I’m going to be concomitantly giving them calcium supplements. Of course, if they have renal insufficiency, then I’m much more cautious. We’ve even seen calcium supplements raise the serum calcium, which you never see with dietary calcium. That’s another potential proof that it might be too much too fast.
For renal patients, even in mild renal insufficiency, maybe even in diabetes where we’ve seen a signal, maybe aim lower in the amount of calcium supplementation if diet is insufficient, and aim a little lower in vitamin D targets, and I think you’ll be in a safer place.
Ms. Ward: Is there anything else you want to add?
Dr. Budoff: The evidence is still evolving. I’d say that it’s interesting and maybe a little frustrating that we don’t have a final answer on all of this. I would stay tuned for more data because we’re looking at many of the epidemiologic studies to try to see what happens in the real world, with both dietary intake of calcium and calcium supplementation.
Ms. Ward: Thank you very much for joining me today.
Dr. Budoff: It’s a pleasure. Thanks for having me.
Dr. Budoff disclosed being a speaker for Amarin Pharma.

As you mentioned, there are a couple of newer studies that point us toward a relationship. I think that we still have a little bit of a mixed bag, but we need to dive a little deeper into that to figure out what’s going on.
Ms. Ward: Does it appear to be connected to calcium in the form of supplements vs calcium from foods?
Dr. Budoff: We looked very carefully at dietary calcium in the MESA study, the multiethnic study of atherosclerosis. There is no relationship between dietary calcium intake and coronary calcium or cardiovascular events. We’re talking mostly about supplements now when we talk about this increased risk that we’re seeing.
Does Vitamin D Exacerbate Risk?
Ms. Ward: Because it’s seen with supplements, is that likely because that’s a much higher concentration of calcium coming in or do you think it’s something inherent in its being in the form of a supplement?
Dr. Budoff: I think there are two things. One, it’s definitely a higher concentration all at once. You get many more milligrams at a time when you take a supplement than if you had a high-calcium food or drink.
Also, most supplements have vitamin D as well. I think vitamin D and calcium work synergistically. When you give them both together simultaneously, I think that may have more of a potentiating effect that might exacerbate any potential risk.
Ms. Ward: Is there any reason to think there might be a difference in type of calcium supplement? I always think of the chalky tablet form vs calcium chews.
Dr. Budoff: I’m not aware of a difference in the supplement type. I think the vitamin D issue is a big problem because we all have patients who take thousands of units of vitamin D — just crazy numbers. People advocate really high numbers and that stays in the system.
Personally, I think part of the explanation is that with very high levels of vitamin D on top of calcium supplementation, you now absorb it better. You now get it into the bone, but maybe also into the coronary arteries. If you’re very high in vitamin D and then are taking a large calcium supplement, it might be the calcium/vitamin D combination that’s giving us some trouble. I think people on vitamin D supplements really need to watch their levels and not get supratherapeutic.
Ms. Ward: With the vitamin D?
Dr. Budoff: With the vitamin D.
Diabetes and Renal Function
Ms. Ward: In some of the studies, there seems to be a higher risk in patients with diabetes. Is there any reason why that would be?
Dr. Budoff: I can’t think of a reason exactly why with diabetes per se, except for renal disease. Patients with diabetes have more intrinsic renal disease, proteinuria, and even a reduced eGFR. We’ve seen that the kidney is very strongly tied to this. We have a very strong relationship, in work I’ve done a decade ago now, showing that calcium supplementation (in the form of phosphate binders) in patients on dialysis or with advanced renal disease is linked to much higher coronary calcium progression.
We did prospective, randomized trials showing that calcium intake as binders to reduce phosphorus led to more coronary calcium. We always thought that was just relegated to the renal population, and there might be an overlap here with the diabetes and more renal disease. I have a feeling that it has to do with more of that. It might be regulation of parathyroid hormone as well, which might be more abnormal in patients with diabetes.
Avoid Supratherapeutic Vitamin D Levels
Ms. Ward:: What are you telling your patients?
Dr. Budoff: I tell patients with normal kidney function that the bone will modulate 99.9% of the calcium uptake. If they have osteopenia or osteoporosis, regardless of their calcium score, I’m very comfortable putting them on supplements.
I’m a little more cautious with the vitamin D levels, and I keep an eye on that and regulate how much vitamin D they get based on their levels. I get them into the normal range, but I don’t want them supratherapeutic. You can even follow their calcium score. Again, we’ve shown that if you’re taking too much calcium, your calcium score will go up. I can just check it again in a couple of years to make sure that it’s safe.
Ms. Ward:: In terms of vitamin D levels, when you’re saying “supratherapeutic,” what levels do you consider a safe amount to take?
Dr. Budoff: I’d like them under 100 ng/mL as far as their upper level. Normal is around 70 ng/mL at most labs. I try to keep them in the normal range. I don’t even want them to be high-normal if I’m going to be concomitantly giving them calcium supplements. Of course, if they have renal insufficiency, then I’m much more cautious. We’ve even seen calcium supplements raise the serum calcium, which you never see with dietary calcium. That’s another potential proof that it might be too much too fast.
For renal patients, even in mild renal insufficiency, maybe even in diabetes where we’ve seen a signal, maybe aim lower in the amount of calcium supplementation if diet is insufficient, and aim a little lower in vitamin D targets, and I think you’ll be in a safer place.
Ms. Ward: Is there anything else you want to add?
Dr. Budoff: The evidence is still evolving. I’d say that it’s interesting and maybe a little frustrating that we don’t have a final answer on all of this. I would stay tuned for more data because we’re looking at many of the epidemiologic studies to try to see what happens in the real world, with both dietary intake of calcium and calcium supplementation.
Ms. Ward: Thank you very much for joining me today.
Dr. Budoff: It’s a pleasure. Thanks for having me.

Another Reason to Control Lp(a): To Protect the Kidneys Too
LYON, FRANCE — High levels of lipoprotein(a) [Lp(a)] in the blood are associated with a significantly increased risk for chronic kidney disease, report investigators who are studying the link in a two-part study of more than 100,000 people.
There is already genetic evidence showing that Lp(a) can cause cardiovascular conditions, including myocardial infarction, aortic valve stenosis, peripheral artery disease, and ischemic stroke.
Now, researchers presenting at the European Atherosclerosis Society (EAS) 2024 Congress are adding new organs – the kidneys – to the list of those that can be damaged by elevated Lp(a).
“This is very important,” said lead investigator Anne Langsted, MD, PhD, DMSc, from the Department of Clinical Biochemistry at the Rigshospitalet in Denmark. And “hopefully, we’ll have a treatment for Lp(a) on the market very soon. Until then, I think individuals who have kidney disease would benefit a lot from reducing other risk factors, if they also have high levels” of Lp(a).
Using data gathered from the Copenhagen General Population Study, the study involved 108,439 individuals who had a range of tests including estimated glomerular filtration rate (eGFR), plasma Lp(a) levels, and LPA genotyping. The patients were then linked to a series of national registries to study outcomes.
The researchers conducted two separate analyses: an observational study of Lp(a) levels in 70,040 individuals and a Mendelian randomization study of LPA kringle IV–type 2 domain repeats in 106,624 individuals. The number of those repeats is inversely associated with median Lp(a) plasma levels.
The observational study showed that eGFR decreased with increasing median plasma Lp(a) levels; the Mendelian randomization study indicated that eGFR decreased KIV-2 repeat numbers dropped.
Across both parts of the study, it was found that each 50 mg/dL increase in plasma Lp(a) levels was associated with an increased risk of at least 25% for chronic kidney disease.
Lp(a) and Chronic Kidney Disease
When high plasma levels of Lp(a) have been spotted before in patients with kidney disease, “we’ve kind of assumed that it was probably the kidney disease that caused the higher levels,” Dr. Langsted said. But her team hypothesized that the opposite was at play and that Lp(a) levels are genetically determined, and increased plasma Lp(a) levels may be causally associated with rising risk for chronic kidney disease.
Gerald F. Watts, MD, PhD, DSc, Winthrop Professor of cardiometabolic and internal medicine at the University of Western Australia in Perth, and co-chair of the study, said in an interview that “although Mendelian randomization is a technique that allows you to infer causality, it’s probably a little bit more complex than that in reality,” adding that there is likely a bidirectional relationship between Lp(a) and chronic kidney disease.
Having increased Lp(a) levels on their own is not sufficient to trigger chronic kidney disease. “You probably need another event and then you get into a vicious cycle,” Dr. Watts said.
The mechanism linking Lp(a) with chronic kidney disease remains unclear, but Dr. Watts explained that the lipoprotein probably damages the renal tubes when it is reabsorbed after it dissociates from low-density lipoprotein cholesterol.
The next step will be to identify the people who are most susceptible to this and figure out what treatment might help. Dr. Watts suggested that gene silencing, in which Lp(a) is “completely obliterated,” will lead to an improvement in renal function.

Colchicine: A New Tool for Ischemic Stroke, CVD Event Recurrence?
BASEL, SWITZERLAND — However, the results did reveal a significant reduction in recurrent stroke and cardiovascular events in the per-protocol analysis and in the subgroup of patients with coronary artery disease.
“Although the primary endpoint was neutral, the CONVINCE results support the hypothesis that long-term anti-inflammatory therapy with colchicine may reduce recurrent stroke and cardiovascular events, specifically in stroke patients with atherosclerosis,” lead investigator Peter Kelly, MD, University College Dublin School of Medicine, Dublin, Ireland, concluded.
The results were presented at the European Stroke Organization Conference (ESOC) 2024.
Inflammation, Dr. Kelly said, plays an important role in the pathophysiology of atherosclerotic plaque, a major cause of cardiovascular events and ischemic strokes.
Colchicine, an established, widely available, low-cost drug that reduces inflammatory response, has been shown to reduce recurrent vascular events in patients with coronary artery disease.
The CONVINCE trial was conducted to see whether colchicine could show similar benefits in patients with non-severe, non-cardioembolic stroke or transient ischemic attack.
Conducted in 16 European countries and Canada, the CONVINCE trial included 3154 patients with a recent non-cardioembolic nondisabling ischemic stroke or high-risk transient ischemic attack. They were randomly assigned to receive colchicine (0.5 mg/d) or placebo.
Key exclusion criteria included evidence of atrial fibrillation or other source of cardioembolism, a defined cause of stroke other than atherosclerosis or small vessel disease, a glomerular filtration rate below 50 mL/min, and the use of drugs that interact with colchicine.
The primary endpoint was a composite of first recurrent ischemic stroke, myocardial infarction, cardiac arrest, or hospitalization for unstable angina. Study participants were followed-up over 36 months.
Results of the primary intention-to-treat analysis showed that the primary endpoint occurred in 153 patients randomized to low-dose colchicine (9.8%) versus 185 in the placebo group (11.8%). This translated into a hazard ratio (HR) of 0.84 (95% CI, 0.68-1.05; P = .12) — a nonsignificant result.
Reduced levels of C-reactive protein in the colchicine group showed the anti-inflammatory effect of treatment with colchicine, Dr. Kelly reported.
In a prespecified on-treatment analysis (excluding patients with major protocol violations), colchicine did show a significant benefit in the primary endpoint (HR, 0.80; 95% CI, 0.63-0.99).
A Novel Target for Stroke Treatment
In addition, significantly reduced rates of recurrent stroke or cardiovascular events were observed in the subgroup of patients with a history of coronary artery disease.
In an updated meta-analysis of existing colchicine studies including CONVINCE, there was a significant reduction in the risk for ischemic stroke (risk ratio, 0.73; 95% CI, 0.58-0.90).
“The signals of benefit of colchicine in secondary analyses are in line with findings from previous trials and indicate the potential of colchicine in prevention after stroke,” Dr. Kelly said.
He pointed out that the COVID pandemic reduced the planned follow-up time in the CONVINCE trial, which led to the study being underpowered for the primary analysis.
“Further trials are needed in all stroke subtypes, but with particular focus on patients with objective evidence of atherosclerosis,” he said.
Commenting on the findings, Mira Katan, MD, University Hospital of Basel, Switzerland, noted that inflammation represents a novel target for stroke treatment.
“We have never before looked at treating inflammation in stroke. Although the primary endpoint was not reached in the CONVINCE study, the on-treatment analysis and meta-analysis showed a risk reduction, and we know colchicine works in cardiology. I think this is a fantastic trial, giving us a new target for stroke therapy,” Dr. Katan said.
“I think we have a new tool, but of course we need further trials to confirm that,” she added.
The CONVINCE trial was supported by Health Research Board Ireland, Deutsche Forschungsgesellschaft, Fonds Wetenschappelijk Onderzoek (FWO), and the Irish Heart Foundation. Dr. Kelly received funding from the Irish Heart Foundation. Dr. Katan reported no relevant disclosures.
