Chronic Loneliness Tied to Increased Stroke Risk
Adults older than 50 years who report experiencing persistently high levels of loneliness have a 56% increased risk for stroke, a new study showed.
The increased stroke risk did not apply to individuals who reported experiencing situational loneliness, a finding that investigators believe bolsters the hypothesis that chronic loneliness is driving the association.
“Our findings suggest that individuals who experience chronic loneliness are at higher risk for incident stroke,” lead investigator Yenee Soh, ScD, research associate of social and behavioral sciences in the Harvard T.H. Chan School of Public Health, Boston, told this news organization. “It is important to routinely assess loneliness, as the consequences may be worse if unidentified and/or ignored.”
The findings were published online in eClinicalMedicine.
Significant, Chronic Health Consequences
Exacerbated by the COVID-19 pandemic, loneliness is at an all-time high. A 2023 Surgeon General’s report highlighted the fact that loneliness and social isolation are linked to significant and chronic health consequences.
Previous research has linked loneliness to cardiovascular disease, yet few studies have examined the association between loneliness and stroke risk. The current study is one of the first to examine the association between changes in loneliness and stroke risk over time.
Using data from the 2006-2018 Health and Retirement Study, researchers assessed the link between loneliness and incident stroke over time. Between 2006 and 2008, 12,161 study participants, who were all older than 50 years with no history of stroke, responded to questions from the Revised UCLA Loneliness Scale. From these responses, researchers created summary loneliness scores.
Four years later, from 2010 to 2012, the 8936 remaining study participants responded to the same 20 questions again. Based on loneliness scores across the two time points, participants were divided into four groups:
- Consistently low (those who scored low on the loneliness scale at both baseline and follow-up).
- Remitting (those who scored high at baseline and low at follow-up).
- Recent onset (those who scored low at baseline and high at follow-up).
- Consistently high (those who scored high at both baseline and follow-up).
Incident stroke was determined by participant report and medical record data.
Among participants whose loneliness was measured at baseline only, 1237 strokes occurred during the 2006-2018 follow-up period. Among those who provided two loneliness assessments over time, 601 strokes occurred during the follow-up period.
Even after adjusting for social isolation, depressive symptoms, physical activity, body mass index, and other health conditions, investigators found that participants who reported being lonely at baseline only had a 25% increased stroke risk, compared with those who did not report being lonely at baseline (hazard ratio [HR], 1.25; 95% confidence interval (CI), 1.06-1.47).
Participants who reported having consistently high loneliness across both time points had a 56% increased risk for incident stroke vs those who did not report loneliness at both time points after adjusting for social isolation and depression (HR, 1.56; 95% CI, 1.11-2.18).
The researchers did not investigate any of the underlying issues that may contribute to the association between loneliness and stroke risk, but speculated there may be physiological factors at play. These could include inflammation caused by increased hypothalamic pituitary-adrenocortical activity, behavioral factors such as poor medication adherence, smoking and/or alcohol use, and psychosocial issues.
Those who experience chronic loneliness may represent individuals that are unable to develop or maintain satisfying social relationships, which may result in longer-term interpersonal difficulties, Dr. Soh noted.
“Since loneliness is a highly subjective experience, seeking help to address and intervene to address a patient’s specific personal needs is important. It’s important to distinguish loneliness from social isolation,” said Dr. Soh.
She added that “by screening for loneliness and providing care or referring patients to relevant behavioral healthcare providers, clinicians can play a crucial role in addressing loneliness and its associated health risks early on to help reduce the population burden of loneliness.”
Progressive Research
Commenting on the findings for this news organization, Elaine Jones, MD, medical director of Access TeleCare, who was not involved in the research, applauded the investigators for “advancing the topic by looking at the chronicity aspect of loneliness.”
She said more research is needed to investigate loneliness as a stroke risk factor and noted that there may be something inherently different among respondents who reported loneliness at both study time points.
“Personality types may play a role here. We know people with positive attitudes and outlooks can do better in challenging health situations than people who are negative in their attitudes, regardless of depression. Perhaps those who feel lonely initially decided to do something about it and join groups, take up a hobby, or re-engage with family or friends. Perhaps the people who are chronically lonely don’t, or can’t, do this,” Dr. Jones said.
Chronic loneliness can cause stress, she added, “and we know that stress chemicals and hormones can be harmful to health over long durations of time.”
The study was funded by the National Institute on Aging. There were no conflicts of interest noted.

Study Finds Major CV Event Risk in Patients With AD Similar to Controls
The results of the analysis were presented during a poster session at the Revolutionizing Atopic Dermatitis conference in Chicago. “While it is known that atopic dermatitis is associated with some comorbidities, the specific risk of major adverse cardiovascular events in patients with AD, especially those with moderate to severe AD within the US population, is unclear,” the study’s first author Christopher G. Bunick, MD, PhD, said in an interview following the conference.
To characterize the risk for MACE in patients with AD vs matched controls without AD (non-AD) and patients with RA, Dr. Bunick, associate professor of dermatology at Yale University, New Haven, Connecticut, and colleagues retrospectively evaluated US claims data from Optum’s Clinformatics Data Mart. The study population consisted of 381,221 patients aged 18 years and older who were diagnosed with AD from March 2017 to March 2023. Comparator groups included 381,221 non-AD controls matched by age, sex, and cohort entry, and 97,445 patients diagnosed with RA based on at least two claims for RA ≥ 7 days apart.
Patients were classified as having moderate to severe disease if they received dupilumab for AD or advanced systemic therapy for RA at any time during the follow-up period. The matched moderate to severe AD and non-AD cohorts were composed of 7134 patients each. The incidence of MACE was defined as inpatient hospitalization with myocardial infarction or stroke. The researchers used multivariable Cox proportional hazard models adjusted for baseline demographics, comorbidities, and medications to calculate the relative risk for MACE.
MACE Incidence, Relative Risk
The mean age of the AD cohort and non-AD matched controls was 58 years, and the mean age of the RA cohort was 67 years. The incidence of MACE per 100 patient-years was 1.78 among patients with AD, 1.83 among non-AD matched controls, and 2.12 among patients with RA. Patients with moderate to severe AD had a MACE incidence of 1.18 per 100 patient-years, which was lower than that of non-AD matched controls (1.52) and patients with moderate to severe RA (1.67).
In other findings, the relative risk for MACE in patients with AD was lower vs non-AD controls (adjusted hazard ratio [aHR], 0.91; 95% CI, 0.89-0.93; P < .001) and patients with RA (aHR, 0.83; 95% CI, 0.80-0.85; P < .001). Among patients with moderate to severe AD, MACE risk was similar to that of non-AD matched controls (aHR, 0.92; 95% CI, 0.73-1.14) and lower vs those with moderate to severe RA (aHR, 0.83; 95% CI, 0.73-0.94; P < .01).
MACE risk associated with AD was greater in patients who were older (per year, aHR, 1.05; 95% CI, 1.05-1.05), male (aHR, 0.81; 95% CI, 0.79-0.84), and Black vs White (aHR, 1.16; 95% CI, 1.11-1.21), and among those who received systemic corticosteroids in the 3 months before diagnosis (aHR, 1.10; 95% CI, 1.06-1.14), were hospitalized in the year before diagnosis (aHR, 1.35; 95% CI, 1.30-1.41), and had a history of smoking (aHR, 1.20; 95% CI, 1.16-1.24) and drug abuse (aHR, 1.34; 95% CI, 1.25-1.43).
Unexpected Results
“One surprising finding was that the incidence of MACE in patients with moderate to severe AD was actually lower than that in non-AD matched controls and significantly lower compared to patients with moderate to severe RA,” Dr. Bunick said. “This contrasts with the expectation that increased systemic inflammation in moderate to severe AD would correspond with a higher incidence of MACE.”
Another unexpected result, he said, was that, among patients with moderate to severe AD, the risk for MACE was not significantly different from that of non-AD matched controls, suggesting that the inflammatory burden in AD might not translate to as high a cardiovascular risk as previously assumed.
Dr. Bunick noted that advanced treatments for AD such as Janus kinase (JAK) inhibitors (upadacitinib and abrocitinib) have a class boxed warning for MACE based on a study of another JAK inhibitor (tofacitinib) in patients with RA, but “this may not apply to AD because patients with AD have a lower risk for MACE.”
In his opinion, he said, the study “underscores the importance of understanding the specific risks associated with different inflammatory conditions.” Moreover, “it emphasizes the potential benefits of newer systemic therapies in potentially mitigating cardiovascular risks in patients with moderate to severe AD.”
Dr. Bunick acknowledged certain limitations of the study, including its retrospective design and reliance on administrative claims data, which “may introduce coding errors and misclassification,” and the generalizability of the results, which may be limited to the US population.
AbbVie funded the study, and three of the coauthors are employees of the company. Dr. Bunick disclosed that he has served as an investigator and/or a consultant for AbbVie, Almirall, Apogee, Arcutis Biotherapeutics, Connect Biopharma, Daiichi Sankyo, EPI Health/Novan, LEO, Lilly, Novartis, Ortho Dermatologics, Palvella Therapeutics, Pfizer, Sanofi Regeneron, Sun, Takeda, Timber, and UCB.

Anticoagulation Shows No Benefit in Preventing Second Stroke
BOSTON — Patients who have had a stroke are thought to be at a higher risk for another one, but oral anticoagulation with edoxaban led to no discernible reduction in the risk for a second stroke, and the risk for major bleeding was more than quadruple the risk with no anticoagulation, a subanalysis of a major European trial has shown.
“There is no interaction between prior stroke or TIA [transient ischemic attack] and the treatment effect, and this is true for the primary outcome and the safety outcome,” Paulus Kirchoff, MD, director of cardiology at the University Heart and Vascular Center in Hamburg, Germany, said during his presentation of a subanalysis of the NOAH-AFNET 6 trial at the annual meeting of the Heart Rhythm Society (HRS) 2024. However, “there is a signal for more safety events in patients randomized to anticoagulation with a prior stroke.”
The subanalysis involved 253 patients who had had a stroke or TIA and who had device-detected atrial fibrillation (AF) from the overall NOAH-AFNET 6 population of 2536 patients, which enrolled patients 65 years and older with at least one additional CHA2DS-VASc risk factor and patients 75 years and older with device-detected subclinical AF episodes of at least 6 minutes. Patients were randomized to either edoxaban or no anticoagulation, but 53.9% of the no-anticoagulation group was taking aspirin at trial enrollment. Anticoagulation with edoxaban was shown to have no significant impact on stroke rates or other cardiovascular outcomes.
Subanalysis Results
In the subanalysis, a composite of stroke, systemic embolism, and cardiovascular death — the primary outcome — was similar in the edoxaban and no-anticoagulation groups (14/122 patients [11.5%] vs 16/131 patients [12.2%]; 5.7% vs 6.3% per patient-year).
The rate of recurrent stroke was also similar in the edoxaban and no-anticoagulation groups (4 of 122 patients [3.3%] vs 6 of 131 patients [4.6%]; 1.6% vs 2.3% per patient-year). And there were eight cardiovascular deaths in each group.
However, edoxaban patients had significantly higher rates of major bleeding.
“This is a subanalysis, so what we see in terms of the number of patients with events is not powered for a definitive answer, but we do see that there were 10 major bleeds in the group of patients with a prior stroke or TIA in NOAH,” Dr. Kirchoff reported. “Eight of those 10 major bleeds occurred in patients randomized to edoxaban.”
Results from the NOAH-AFNET 6 trial have been compared with those from the ARTESiA trial, which compared apixaban anticoagulation with aspirin in patients with subclinical AF and was also presented at HRS 2024. ARTESiA showed that apixaban significantly lowered the risk for stroke and systemic embolism.
“In ARTESiA, everyone was on aspirin when they were randomized to no anticoagulation; in NOAH, only about half were on aspirin,” Dr. Kirchoff said.
Both studies had similar outcomes for cardiovascular death in the anticoagulation and no-anticoagulation groups. “It’s not significant; it may be chance, but it’s definitely not the reduction in death that we have seen in the anticoagulant trials,” Dr. Kirchoff said. “When you look at the meta-analyses of the early anticoagulation trials, there’s a one third reduction in death, and here we’re talking about a smaller reduction.”
This research points to a need for a better way to evaluate stroke risk. “We need new markers,” Dr. Kirchoff said. “Some of them may be in the blood or imaging, genetics maybe, and one thing that really emerges from my perspective is that we now have the first evidence to suggest that patients with a very low atrial fibrillation burden have a low stroke rate.”
More research is needed to better understand AF characteristics and stroke risk, he said.
AF Care Enters a ‘Gray Zone’
The NOAH-AFNET 6 results, coupled with those from ARTESiA, are changing the paradigm for anticoagulation in patients with stroke, said Taya Glotzer, MD, an electrophysiologist at the Hackensack University Medical Center in Hackensack, New Jersey, who compiled her own analysis of the studies’ outcomes.
“In ARTESiA, the stroke reduction was only 0.44% a year, with a number needed to treat of 250,” she said. “In the NOAH-AFNET 6 main trial, the stroke reduction was 0.2%, with the number needed to treat of 500, and in the NOAH prior stroke patients, there was a 0.7% reduction, with a number needed to treat of 143.”
None of these trials would meet the standard for a class 1 recommendation for anticoagulation with a reduction of even 1%-2% per year, she noted, but they do show that the stroke rate “is very, very low” in prior patients with stroke.
“Prior to 2024, we knew what was black and white; we knew who to anticoagulate and who not to anticoagulate. And now we are in a gray zone, trying to balance the risk of stroke and bleeding. We have to individualize or hope for substudies, perhaps using the CHA2DS-VASc score or other information about the left atrium, to help us make decisions in these patients. It’s not just going to be black and white,” she said.

BOSTON — Patients who have had a stroke are thought to be at a higher risk for another one, but oral anticoagulation with edoxaban led to no discernible reduction in the risk for a second stroke, and the risk for major bleeding was more than quadruple the risk with no anticoagulation, a subanalysis of a major European trial has shown.
“There is no interaction between prior stroke or TIA [transient ischemic attack] and the treatment effect, and this is true for the primary outcome and the safety outcome,” Paulus Kirchoff, MD, director of cardiology at the University Heart and Vascular Center in Hamburg, Germany, said during his presentation of a subanalysis of the NOAH-AFNET 6 trial at the annual meeting of the Heart Rhythm Society (HRS) 2024. However, “there is a signal for more safety events in patients randomized to anticoagulation with a prior stroke.”
The subanalysis involved 253 patients who had had a stroke or TIA and who had device-detected atrial fibrillation (AF) from the overall NOAH-AFNET 6 population of 2536 patients, which enrolled patients 65 years and older with at least one additional CHA2DS-VASc risk factor and patients 75 years and older with device-detected subclinical AF episodes of at least 6 minutes. Patients were randomized to either edoxaban or no anticoagulation, but 53.9% of the no-anticoagulation group was taking aspirin at trial enrollment. Anticoagulation with edoxaban was shown to have no significant impact on stroke rates or other cardiovascular outcomes.

GLP-1s Reduced Secondary Stroke Risk in Patients With Diabetes, Obesity
study was published online in the International Journal of Stoke.
, according to authors of a recent meta-analysis. With benefits across administration routes, dosing regimens, type 2 diabetes status, and total and nonfatal strokes, the findings could improve GLP-1 RA implementation by stroke specialists in patients with stroke history and concurrent type 2 diabetes or obesity, authors said. TheExtending Longevity
Agents including GLP-1 RAs that have been found to reduce cardiovascular events among patients with type 2 diabetes and patients who are overweight or obese also reduce risk of recurrent stroke among patients with a history of stroke who are overweight, obese, or have metabolic disease, said American Heart Association (AHA) Chief Clinical Science Officer Mitchell S. V. Elkind, MD, who was not involved with the study but was asked to comment.
“Stroke is a leading cause of mortality and the leading cause of serious long-term disability,” he added, “so medications that help to reduce that risk can play an important role in improving overall health and well-being and hopefully reducing premature mortality.”
Investigators Anastasia Adamou, MD, an internal medicine resident at AHEPA University Hospital in Thessaloniki, Greece, and colleagues searched MEDLINE and Scopus for cardiovascular outcome trials involving adults randomly assigned to GLP-1 RAs or placebo through November 2023, ultimately analyzing 11 randomized controlled trials (RCTs).
Among 60,380 participants in the nine studies that assessed total strokes, 2.5% of the GLP-1 RA group experienced strokes during follow-up, versus 3% in the placebo group (relative risk [RR] 0.85, 95% confidence interval [CI] 0.77-0.93). Regarding secondary outcomes, the GLP-1 RA group showed a significantly lower rate of nonfatal strokes versus patients on placebo (RR 0.87, 95% CI 0.79-0.95). Conversely, investigators observed no significant risk difference among the groups regarding fatal strokes, probably due to the low rate of events — 0.3% and 0.4% for treated and untreated patients, respectively.
Subgroup analyses revealed no interaction between dosing frequency and total, nonfatal, or fatal strokes. The investigators observed no difference in nonfatal strokes among participants by type 2 diabetes status and medication administration route (oral versus subcutaneous).
“The oral administration route could provide the advantage of lower local ecchymoses and allergic reactions due to subcutaneous infusions,” Dr. Adamou said in an interview. But because oral administration demands daily intake, she added, treatment adherence might be affected. “For this reason, our team performed another subgroup analysis to compare the once-a-day to the once-a-month administration. No interaction effect was again presented between the two subgroups. This outcome allows for personalization of the administration method for each patient.”
Addressing Underutilization
Despite more than 2 decades of widespread use and well-established effects on body weight, HbA1c, and cardiovascular risk, GLP-1 RAs remain underutilized, authors wrote. This is especially true in primary care, noted one study published in Clinical Diabetes.
“GLP-1 RAs have been used for many years to treat diabetic patients,” said Dr. Adamou. But because their impact on cardiovascular health regardless of diabetic status is only recently known, she said, physicians are exercising caution when prescribing this medication to patients without diabetes. “This is why more studies need to be available, especially RCTs.”
Most neurologists traditionally have left management of type 2 diabetes and other metabolic disorders to primary care doctors, said Dr. Elkind. “However, these medications are increasingly important to vascular risk reduction and should be considered part of the stroke specialist’s armamentarium.”
Vascular neurologists can play an important role in managing metabolic disease and obesity by recommending GLP-1 RAs for patients with a history of stroke, or by initiating these medications themselves, Dr. Elkind said. “These drugs are likely to become an important part of stroke patients’ medication regimens, along with antithrombotic agents, blood pressure control, and statins. Neurologists are well-positioned to educate other physicians about the important connections among brain, heart, and metabolic health.”
To that end, he said, the AHA will update guidelines for both primary and secondary stroke prevention as warranted by evidence supporting GLP-1 RAs and other medications that could impact stroke risk in type 2 diabetes and related metabolic disorders. However, no guidelines concerning use of GLP-1 RAs for secondary stroke prevention in obesity exist. Here, said Dr. Elkind, the AHA will continue building on its innovative Cardiovascular-Kidney Metabolic Health program, which includes clinical suggestions and may include more formal clinical practice guidelines as the evidence evolves.
Among the main drivers of the initiative, he said, is the recognition that cardiovascular disease — including stroke — is the major cause of death and morbidity among patients with obesity, type 2 diabetes, and metabolic disorders. “Stroke should be considered an important part of overall cardiovascular risk, and the findings that these drugs can help to reduce the risk of stroke specifically is an important additional reason for their use.”
Dr. Elkind and Dr. Adamou reported no conflicting interests. The authors received no financial support for the study.

FROM THE INTERNATIONAL JOURNAL OF STROKE
Early-Life Excess Weight Tied to Subsequent Stroke Risk
, new research suggested.
An analysis of more than five decades of health data on 10,000 adults revealed that close to 5% experienced a stroke during the follow-up period, with the risk for ischemic stroke being more than twice as high in women who had obesity as teens or young adults. The risk was even higher for hemorrhagic stroke in both men and women with a history of obesity in youth.
“Our findings suggest that being overweight may have long-term health effects, even if the excess weight is temporary,” lead author Ursula Mikkola, BM, an investigator in the Research Unit of Population Health at the University of Oulu, Oulu, Finland, said in a news release.
“Health care professionals should pay attention to overweight and obesity in young people and work with them to develop healthier eating patterns and physical activity — however, conversations with teens and young adults about weight should be approached in a nonjudgmental and nonstigmatizing manner,” she added.
The study was published online in Stroke.
Gender Differences
Childhood obesity has been associated with a heightened risk for cerebrovascular disease later in life, but most studies have focused on body mass index (BMI) at a single time point without considering its fluctuations throughout life, the investigators noted.
For the study, investigators used data from the Northern Finland Birth Cohort 1966, a prospective, general population-based birth cohort that followed 10,491 individuals (5185 women) until 2020 or the first stroke, death, or moving abroad, whichever came first.
Mean (SD) follow-up for each participant was 39 years from age 14 onward and 23 years from age 31 onward. The analysis was conducted between 1980 and 2020.
BMI data were collected from participants at the age of 14 and 31 years. Age 14 covariates included smoking, parental socioeconomic status, and age at menarche (for girls). Age 31 covariates included smoking and participants’ educational level.
During the follow-up period, 4.7% of participants experienced stroke. Of these events, 31% were ischemic strokes and 40% were transient ischemic attacks. The remainder were hemorrhagic or other cerebrovascular events.
Using normal weight as a reference, researchers found that the risk for ischemic stroke was over twice as high for women who had been overweight at ages 14 (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.44-4.31) and 31 (HR, 2.13; 95% CI, 1.14-3.97) years. The risk was also considerably higher for women who had obesity at ages 14 (HR, 1.87; 95% CI, 0.76-4.58) and 31 (HR, 2.67; 95% CI, 1.26-5.65) years.
The risk for hemorrhagic stroke was even higher, both among women (HR, 3.49; 95% CI, 1.13-10.7) and men (HR, 5.75; 95% CI, 1.43-23.1) who had obesity at age 31.
No similar associations were found among men, and the findings were independent of earlier or later BMI.
The risk for any cerebrovascular disease related to overweight at age 14 was twice as high among girls vs boys (HR, 2.09; 95% CI, 1.06-4.15), and the risk for ischemic stroke related to obesity at age 31 was nearly seven times higher among women vs men (HR, 6.96; 95% CI, 1.36-35.7).
“Stroke at a young age is rare, so the difference of just a few strokes could have an outsized impact on the risk estimates,” the study authors said. “Also, BMI relies solely on a person’s height and weight; therefore, a high BMI may be a misleading way to define obesity, especially in muscular people who may carry little fat even while weighing more.”
Caveats
In an accompanying editorial, Larry Goldstein, MD, chair of the Department of Neurology, University of Kentucky, Lexington, Kentucky, and codirector of the Kentucky Neuroscience Institute, said the study “provides additional evidence of an association between overweight/obesity and stroke in young adults.”
However, Dr. Goldstein added that “while it is tempting to assume that reductions in overweight/obesity in younger populations would translate to lower stroke rates in young adults, this remains to be proven.”
Moreover, it is “always important to acknowledge that associations found in observational studies may not reflect causality.”

An analysis of more than five decades of health data on 10,000 adults revealed that close to 5% experienced a stroke during the follow-up period, with the risk for ischemic stroke being more than twice as high in women who had obesity as teens or young adults. The risk was even higher for hemorrhagic stroke in both men and women with a history of obesity in youth.
“Our findings suggest that being overweight may have long-term health effects, even if the excess weight is temporary,” lead author Ursula Mikkola, BM, an investigator in the Research Unit of Population Health at the University of Oulu, Oulu, Finland, said in a news release.
“Health care professionals should pay attention to overweight and obesity in young people and work with them to develop healthier eating patterns and physical activity — however, conversations with teens and young adults about weight should be approached in a nonjudgmental and nonstigmatizing manner,” she added.
The study was published online in Stroke.
Gender Differences
Childhood obesity has been associated with a heightened risk for cerebrovascular disease later in life, but most studies have focused on body mass index (BMI) at a single time point without considering its fluctuations throughout life, the investigators noted.
For the study, investigators used data from the Northern Finland Birth Cohort 1966, a prospective, general population-based birth cohort that followed 10,491 individuals (5185 women) until 2020 or the first stroke, death, or moving abroad, whichever came first.
Mean (SD) follow-up for each participant was 39 years from age 14 onward and 23 years from age 31 onward. The analysis was conducted between 1980 and 2020.
BMI data were collected from participants at the age of 14 and 31 years. Age 14 covariates included smoking, parental socioeconomic status, and age at menarche (for girls). Age 31 covariates included smoking and participants’ educational level.
During the follow-up period, 4.7% of participants experienced stroke. Of these events, 31% were ischemic strokes and 40% were transient ischemic attacks. The remainder were hemorrhagic or other cerebrovascular events.
Using normal weight as a reference, researchers found that the risk for ischemic stroke was over twice as high for women who had been overweight at ages 14 (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.44-4.31) and 31 (HR, 2.13; 95% CI, 1.14-3.97) years. The risk was also considerably higher for women who had obesity at ages 14 (HR, 1.87; 95% CI, 0.76-4.58) and 31 (HR, 2.67; 95% CI, 1.26-5.65) years.
The risk for hemorrhagic stroke was even higher, both among women (HR, 3.49; 95% CI, 1.13-10.7) and men (HR, 5.75; 95% CI, 1.43-23.1) who had obesity at age 31.
No similar associations were found among men, and the findings were independent of earlier or later BMI.
The risk for any cerebrovascular disease related to overweight at age 14 was twice as high among girls vs boys (HR, 2.09; 95% CI, 1.06-4.15), and the risk for ischemic stroke related to obesity at age 31 was nearly seven times higher among women vs men (HR, 6.96; 95% CI, 1.36-35.7).
“Stroke at a young age is rare, so the difference of just a few strokes could have an outsized impact on the risk estimates,” the study authors said. “Also, BMI relies solely on a person’s height and weight; therefore, a high BMI may be a misleading way to define obesity, especially in muscular people who may carry little fat even while weighing more.”
Caveats
In an accompanying editorial, Larry Goldstein, MD, chair of the Department of Neurology, University of Kentucky, Lexington, Kentucky, and codirector of the Kentucky Neuroscience Institute, said the study “provides additional evidence of an association between overweight/obesity and stroke in young adults.”
However, Dr. Goldstein added that “while it is tempting to assume that reductions in overweight/obesity in younger populations would translate to lower stroke rates in young adults, this remains to be proven.”
Moreover, it is “always important to acknowledge that associations found in observational studies may not reflect causality.”
This study was supported by Orion Research Foundation, Päivikki and Sakari Sohlberg Foundation, and Paulo Foundation. Dr. Mikkola reported no relevant financial relationships. The other authors’ disclosures are listed on the original paper. Dr. Goldstein reported no relevant financial relationships.

Narcolepsy an Independent Cardiovascular Disease Risk Factor
HOUSTON — Narcolepsy is associated with a significantly increased risk for cardiovascular disease (CVD) and major adverse cardiac events (MACEs), independent of common comorbid conditions and medications commonly used to treat the chronic sleep disorder, according to two new studies.
A nationwide analysis revealed that people with narcolepsy had a 77% higher risk for CVD and an 82% higher risk for MACE than those without the disorder.
“These findings indicate that it is important for clinicians to regularly monitor patients for cardiovascular disease and take this into consideration when recommending specific treatments for narcolepsy,” study investigators Christopher Kaufmann, PhD; Munaza Riaz, PharmD, MPhil; and Rakesh Bhattacharjee, MD, told this news organization.
“Additionally, physicians should consider monitoring the presence of other health conditions as contributing factors to the risk of CVD,” they said. Dr. Kaufmann and Dr. Riaz are with the University of Florida, Gainesville, Florida, and Dr. Bhattacharjee is with the University of California, San Diego.
They presented their research at SLEEP 2024: 38th Annual Meeting of the Associated Professional Sleep Societies.
Independent Risk Factor
The National Institute of Neurological Disorders and Stroke reports an estimated 125,000 to 200,000 people in the United States live with narcolepsy. The condition often coexists with other common health conditions including obstructive sleep apnea (OSA), diabetes, and other comorbidities, which can all contribute to the risk for CVD.
This raises doubt as to whether narcolepsy itself directly leads to CVD or if it is the result of these comorbid health conditions. Additionally, some medications used to treat narcolepsy carry their own cardiovascular risks.
Using the IBM MarketScan Commercial and Medicare supplemental databases, the researchers identified 34,562 adults with a diagnosis of narcolepsy and a propensity-matched comparison cohort of 100,405 adults without narcolepsy. The patients had a mean age of 40 years, and 62% were women.
Compared with adults without narcolepsy, those with the chronic sleep disorder that causes overwhelming daytime drowsiness had a 77% increased risk for any CVD (hazard ratio [HR], 1.77) and an 82% increased risk for MACE (HR, 1.82).
They also had an increased risk for stroke (HR, 2.04), heart failure or myocardial infarction (MI; HR, 1.64), and atrial fibrillation (HR, 1.58).
The results were similar in a separate analysis of the same population that also controlled for baseline use of stimulants, oxybates, and wake-promoting agents — medications commonly used to treat excessive daytime sleepiness associated with narcolepsy.
In this analysis, narcolepsy was associated with an 89% higher risk for CVD (HR, 1.89) and a 95% increased risk for MACE (HR, 1.95). The risk for any stroke (HR, 2.06), heart failure (HR, 1.90), atrial fibrillation (HR, 1.66), and MI (HR, 1.93) was also higher in those with narcolepsy.
“Our study found that even after considering the presence of health conditions like obstructive sleep apnea, diabetes, hypertension, hyperlipidemia, and even depression, as well as medication use, there still appears to be an independent relationship between narcolepsy and CVD,” the investigators said.
They cautioned that the mechanisms explaining the link between CVD and narcolepsy are unclear and warrant further study.
“Sleep fragmentation is a hallmark of narcolepsy, and it is speculated that this fragmentation, which may trigger disturbances in autonomic function, predisposes individuals to CVD. In rodent models, a possible link has been observed between hypocretin — a central neurotransmitter that is reduced or deficient in patients with narcolepsy — and atherosclerosis.
“However, it remains uncertain whether this is the primary mechanism related to CVD,” they commented.
Compelling Evidence for Higher CVD
Commenting on the findings for this news organization, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, Florida, called for narcolepsy to be recognized as a significant contributor to higher CVD risk.
“Given the compelling evidence linking narcolepsy to a higher incidence of cardiovascular disease, it is crucial that narcolepsy be included in clinical guidelines and risk assessment tools alongside other known risk factors,” said Dr. Lakhan, who was not involved in this research.
“Physicians and health care providers should proactively address the increased cardiovascular risk associated with narcolepsy by incorporating preventive strategies and interventions into the management of patients with this condition,” Dr. Lakhan suggested.
Regular CVD screening, a healthier lifestyle, and targeted therapies could all decrease cardiac risk, Dr. Lakhan added.
“Ultimately, novel disease-modifying therapies for narcolepsy should target the core mechanisms driving the increased cardiovascular risk associated with this condition. By elucidating the specific biological pathways and developing targeted therapies that address the unique challenges faced by narcolepsy patients, we can effectively mitigate the risk,” Dr. Lakhan said.
The studies were funded by the Sleep Research Society Foundation. The authors and Dr. Lakhan had no relevant disclosures.

FROM SLEEP 2024
Helping Patients Cut Down on Sodium: Useful Substitutes and Strategies
Humans have used salt for centuries, to preserve or cure food before refrigeration was readily available, and even as currency in some cultures. Though modern food preservation efforts have decreased our reliance on salt, we still heavily incorporate it as a flavor enhancer.
It’s only relatively recently that we’ve begun limiting salt in our diets, as research has linked high sodium intake with chronic, preventable conditions like hypertension, heart disease, and kidney disease.
How to Recommend Restriction in a Helpful Way
The US Department of Agriculture’s Dietary Guidelines for Americans recommends intake of no more than 2300 mg of sodium daily for adults and children aged 14 years or older. This echoes similar recommendations for people at risk for heart disease, kidney disease, and hypertension. However, the sodium intake of the average American still sits at a whopping 3400 mg daily.
High sodium intake is primarily the result of modern commercial food processing. Food prepared outside the home accounts for up to 70% of sodium intake in the United States, whereas only about 10% comes from salt that is added to food either during or after cooking. For this reason, I hesitate to recommend withholding salt as a primary focus when counseling on a low-sodium diet.
To many people, certain foods just taste better with salt. Many of my patients in the southern United States simply will not eat foods like eggs and tomatoes if they cannot salt them. We can spend every moment of patient interaction time explaining why excess sodium is unhealthy, but the fact remains that humans prefer food that tastes good. This is why I try to avoid counseling a “no-added-salt” diet; instead, I recommend a low-sodium diet with a focus on fresh, whole foods and limiting salt to only a few food items.
Patients should be counseled to slowly restrict their salt intake and be made aware that doing so may increase the time it takes for their sensitivity to the taste of less salty foods to return. But it is also important for them to know that it will return. The surest way to kill progress is for an unprepared patient to believe that their food will taste bland forever. A prepared patient understands that their food may taste different for a couple of weeks, but that the change will not last forever.
Types of Salt
I have often worked with patients who insist that their sodium intake is acceptable because they are using sea salt instead of table salt. This is the result of exceptional marketing and misinformation.
Specialty salts like sea salt and Himalayan pink salt contain about 560 mg and 590 mg of sodium, respectively, per quarter teaspoon. These products do have a slightly different mineral content, with sea salt typically having a negligible amount of calcium, magnesium, or potassium. The very small amount of these minerals offers no obvious health benefits compared with more affordable table salt.
The sodium content of iodized table salt is comparable to these products, with about 590 mg of sodium per quarter teaspoon. Though its high sodium content will put some practitioners off, it is also an excellent source of iodine, at about 75 mg per serving. It has been estimated that upward of 35% of the US population has iodine deficiency, most commonly due to pregnancy, avoidance of dairy products, increasing rates of vegetarianism, intake of highly processed foods, and avoidance of added salt. For this reason, and its relative affordability, I find table salt to be far more appropriate for the average American than specialty salts.
Salt Substitutes
Monosodium glutamate (MSG). MSG was previously at the center of public health concern owing to reports of “Chinese restaurant syndrome” that have since been debunked. I often recommend MSG to people trying to decrease sodium intake because the US Food and Drug Administration has designated it as GRAS (“generally recognized as safe”), and it has about one quarter of the sodium content of table salt at 125 mg per quarter teaspoon. Its crystalline structure makes it a lower-sodium salt substitute in savory applications like soups, stews, and gravies.
Hot sauce. These sauces are generally composed of peppers, vinegar, salt, and sugar. There may be some variation and occasionally added ingredients depending upon the brand. However, I find most hot sauces to be a low-sodium seasoning option that works especially well on proteins like eggs, chicken, and pork.
Potassium-based substitutes. Salt alternatives such as Nu-Salt and Morton Salt Substitute are sodium-free options with a significant amount of potassium, at 525 mg per quarter-teaspoon serving. These alternatives may not be ideal for patients with kidney problems, but they can be very helpful for those with potassium deficiency.
Herb-based seasonings. Garlic and onion powder are both sodium-free seasonings that many of my patients have found help to increase palatability while decreasing salt use. Black pepper; lemon and lime juice; salt-free herb mixes like Mrs. Dash; and spices like cumin, paprika, dill, chili powder, and ginger are also sodium-free or low-sodium alternatives that can help to alleviate blandness for someone new to a low-sodium diet. I recommend them often and use them in my own cooking at home.
Plant-based diet. If the goal of care is to improve cardiovascular or kidney health, then I find that working with patients to increase intake of plant foods to be a helpful option. This way of eating encourages replacing highly processed foods that may be high in sodium and sugar with plants that tend to be higher in potassium and calcium. The Dietary Approaches to Stop Hypertension (DASH), Mediterranean, and other plant-based diets have been shown to increase cardiovascular and metabolic health by significantly decreasing serum lipids, blood pressure, and hemoglobin A1c and promoting weight loss. They have also been shown to increase the gut microbiome and promote increased cognitive function.
I rarely encourage the use of added salt. However, research shows that putting down the salt shaker is probably not the most effective option to restrict sodium intake. For those who can cut back, these options can help keep food flavorful and patients compliant.

These alternatives may not be ideal for patients with kidney problems, but they can be very helpful for those with potassium deficiency.
Herb-based seasonings. Garlic and onion powder are both sodium-free seasonings that many of my patients have found help to increase palatability while decreasing salt use. Black pepper; lemon and lime juice; salt-free herb mixes like Mrs. Dash; and spices like cumin, paprika, dill, chili powder, and ginger are also sodium-free or low-sodium alternatives that can help to alleviate blandness for someone new to a low-sodium diet. I recommend them often and use them in my own cooking at home.
Plant-based diet. If the goal of care is to improve cardiovascular or kidney health, then I find that working with patients to increase intake of plant foods to be a helpful option. This way of eating encourages replacing highly processed foods that may be high in sodium and sugar with plants that tend to be higher in potassium and calcium. The Dietary Approaches to Stop Hypertension (DASH), Mediterranean, and other plant-based diets have been shown to increase cardiovascular and metabolic health by significantly decreasing serum lipids, blood pressure, and hemoglobin A1c and promoting weight loss. They have also been shown to increase the gut microbiome and promote increased cognitive function.
I rarely encourage the use of added salt. However, research shows that putting down the salt shaker is probably not the most effective option to restrict sodium intake. For those who can cut back, these options can help keep food flavorful and patients compliant.

Humans have used salt for centuries, to preserve or cure food before refrigeration was readily available, and even as currency in some cultures. Though modern food preservation efforts have decreased our reliance on salt, we still heavily incorporate it as a flavor enhancer.
It’s only relatively recently that we’ve begun limiting salt in our diets, as research has linked high sodium intake with chronic, preventable conditions like hypertension, heart disease, and kidney disease.
How to Recommend Restriction in a Helpful Way
The US Department of Agriculture’s Dietary Guidelines for Americans recommends intake of no more than 2300 mg of sodium daily for adults and children aged 14 years or older. This echoes similar recommendations for people at risk for heart disease, kidney disease, and hypertension. However, the sodium intake of the average American still sits at a whopping 3400 mg daily.
High sodium intake is primarily the result of modern commercial food processing. Food prepared outside the home accounts for up to 70% of sodium intake in the United States, whereas only about 10% comes from salt that is added to food either during or after cooking. For this reason, I hesitate to recommend withholding salt as a primary focus when counseling on a low-sodium diet.
To many people, certain foods just taste better with salt. Many of my patients in the southern United States simply will not eat foods like eggs and tomatoes if they cannot salt them. We can spend every moment of patient interaction time explaining why excess sodium is unhealthy, but the fact remains that humans prefer food that tastes good. This is why I try to avoid counseling a “no-added-salt” diet; instead, I recommend a low-sodium diet with a focus on fresh, whole foods and limiting salt to only a few food items.
Patients should be counseled to slowly restrict their salt intake and be made aware that doing so may increase the time it takes for their sensitivity to the taste of less salty foods to return. But it is also important for them to know that it will return. The surest way to kill progress is for an unprepared patient to believe that their food will taste bland forever. A prepared patient understands that their food may taste different for a couple of weeks, but that the change will not last forever.
Types of Salt
I have often worked with patients who insist that their sodium intake is acceptable because they are using sea salt instead of table salt. This is the result of exceptional marketing and misinformation.
Specialty salts like sea salt and Himalayan pink salt contain about 560 mg and 590 mg of sodium, respectively, per quarter teaspoon. These products do have a slightly different mineral content, with sea salt typically having a negligible amount of calcium, magnesium, or potassium. The very small amount of these minerals offers no obvious health benefits compared with more affordable table salt.
The sodium content of iodized table salt is comparable to these products, with about 590 mg of sodium per quarter teaspoon. Though its high sodium content will put some practitioners off, it is also an excellent source of iodine, at about 75 mg per serving. It has been estimated that upward of 35% of the US population has iodine deficiency, most commonly due to pregnancy, avoidance of dairy products, increasing rates of vegetarianism, intake of highly processed foods, and avoidance of added salt. For this reason, and its relative affordability, I find table salt to be far more appropriate for the average American than specialty salts.
Salt Substitutes
Monosodium glutamate (MSG). MSG was previously at the center of public health concern owing to reports of “Chinese restaurant syndrome” that have since been debunked. I often recommend MSG to people trying to decrease sodium intake because the US Food and Drug Administration has designated it as GRAS (“generally recognized as safe”), and it has about one quarter of the sodium content of table salt at 125 mg per quarter teaspoon. Its crystalline structure makes it a lower-sodium salt substitute in savory applications like soups, stews, and gravies.
Hot sauce. These sauces are generally composed of peppers, vinegar, salt, and sugar. There may be some variation and occasionally added ingredients depending upon the brand. However, I find most hot sauces to be a low-sodium seasoning option that works especially well on proteins like eggs, chicken, and pork.
Potassium-based substitutes. Salt alternatives such as Nu-Salt and Morton Salt Substitute are sodium-free options with a significant amount of potassium, at 525 mg per quarter-teaspoon serving.

Sugar Substitute Tied to Higher Risk for Heart Attack, Stroke
High levels of xylitol, a low-calorie sweetener used in many reduced-sugar foods as well as gum and toothpaste, are linked to an increased risk of heart attacks, strokes, and death, says a new study published in the European Heart Journal.
The research team studied more than 3000 people in the US and Europe over 3 years and found that people with the highest amount of xylitol in their plasma were more likely to have a problem with their heart or blood vessels.
To show the early effects of xylitol, researchers studied platelet activity in volunteers who consumed a xylitol-sweetened drink and a glucose-sweetened drink. The xylitol levels went up by 1000 times in people after the xylitol drink but not after the glucose-sweetened drink.
Xylitol is naturally found in small amounts in fruit and vegetables, and it’s been used more as a sugar substitute over the past decade in processed foods, toothpaste, chewing gum, and other products.
“This study again shows the immediate need for investigating sugar alcohols and artificial sweeteners, especially as they continue to be recommended in combating conditions like obesity or diabetes,” Stanley Hazen, MD, chair of the Department of Cardiovascular and Metabolic Sciences at Cleveland Clinic’s Lerner Research Institute, Cleveland, Ohio, said in a news release.
“It does not mean throw out your toothpaste if it has xylitol in it, but we should be aware that consumption of a product containing high levels could increase the risk of blood clot-related events.”
A similar link between erythritol, another sugar substance, and problems with the heart and blood vessels was found last year by the same research team, the release said.
In a response to the study, the Calorie Control Council, a trade association representing the low- and reduced-calorie food and beverage industry, said xylitol has been approved for decades by government agencies. The study results may not apply to the general population because some people in the study already had a higher risk of having problems with their heart and blood vessels, it said.

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
Commonly Used Meds Tied to Lower Risk for Brain Aneurysm Rupture
(aSAH), a drug-wide association study suggested.
The blood pressure drug lisinopril; the cholesterol drug simvastatin; the diabetes drug metformin; and the drug tamsulosin, prescribed for an enlarged prostate, were all associated with decreased aSAH risk, investigators found.
Conversely, four other drugs were associated with an increased risk for this severely morbid, often deadly, condition.
“The motivation for this study was the fact that we can currently prevent bleeding from intracranial aneurysms only by invasive treatment of those aneurysms with inherent complication risks,” said study investigator Ynte Ruigrok, MD, PhD, associate professor of neurology and neurosurgery, University Medical Center Utrecht, Utrecht, the Netherlands. “Drugs to reduce or eliminate this risk are not yet available. This study is a first step in identifying such drugs.”
The findings were published online in Neurology.
Surprising Results
For the study, the researchers used the Secure Anonymized Information Linkage data bank in Wales to identify 4879 patients with aSAH between January 2000 and December 2019 and 43,911 patients without aSAH matched on age, sex, and year of database entry. Clustering resulted in 2023 unique drugs, of which 205 were commonly prescribed.
After adjusting for other factors such as high blood pressure, alcohol abuse, smoking, and a total number of health conditions, the results yielded two surprises, Dr. Ruigrok observed.
The first was a significant decrease in aSAH risk for current use of lisinopril, compared with nonuse (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.44-0.90), and a nonsignificant decrease with current use of amlodipine (OR, 0.82; 95% CI, 0.65-1.04).
“Hypertension is a major risk factor for occurrence and bleeding from aneurysms. If there is indeed a specific blood pressure–lowering drug that not only has a blood pressure–lowering effect but also has additional protection against aSAH, then perhaps that drug should become the drug of choice in aneurysm patients in the future,” he said.
Notably, recent use of both drugs, defined as between 1 year and 3 months before the index date, was associated with an increased risk for aSAH. This trend was not found for other antihypertensives and was significant for amlodipine but not lisinopril.
The reasons are unclear, but “we trust the findings on lisinopril more,” Dr. Ruigrok said. “The findings on amlodipine may be due to confounding by indication, specifically caused by hypertension. Therefore, it is important to validate our findings in an independent research cohort, and we are in the process of doing so.”
The study’s second surprise was the antidiabetic drug metformin and cholesterol-lowering drug simvastatin were also associated with reduced aSAH risk, Dr. Ruigrok noted.
“We already knew from previous studies that diabetes and high cholesterol are protective factors for aSAH,” he said. “Our results suggest that perhaps not the conditions themselves are protective for aSAH but rather the drugs used to treat these conditions with are.”
The risk for a ruptured brain aneurysm among current users was 42% lower with metformin (OR, 0.58; 95% CI, 0.43-0.78), 22% lower with simvastatin (OR, 0.78; 95% CI, 0.64-0.96), and 45% lower with tamsulosin (OR, 0.55; 95% CI, 0.32-0.93).
An increased risk for aSAH was found only in current users of warfarin (OR, 1.35; 95% CI, 1.02-1.79), venlafaxine (OR, 1.67; 95% CI, 1.01-2.75), prochlorperazine (OR, 2.15; 95% CI, 1.45-3.18), and co-codamol (OR, 1.31; 95% CI, 1.10-1.56).
Other drugs within the classes of vitamin K antagonists, serotonin reuptake inhibitors, conventional antipsychotics, and compound analgesics did not show an association with aSAH.
The study was limited by the use of drug prescriptions, and patients may not take their drugs or use them incorrectly, noted the researchers, led by Jos P. Kanning, MSc, also with University Medical Center Utrecht.
The study was supported by the European Research Council. The authors reported no relevant financial relationships.

After adjusting for other factors such as high blood pressure, alcohol abuse, smoking, and a total number of health conditions, the results yielded two surprises, Dr. Ruigrok observed.
The first was a significant decrease in aSAH risk for current use of lisinopril, compared with nonuse (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.44-0.90), and a nonsignificant decrease with current use of amlodipine (OR, 0.82; 95% CI, 0.65-1.04).
“Hypertension is a major risk factor for occurrence and bleeding from aneurysms. If there is indeed a specific blood pressure–lowering drug that not only has a blood pressure–lowering effect but also has additional protection against aSAH, then perhaps that drug should become the drug of choice in aneurysm patients in the future,” he said.
Notably, recent use of both drugs, defined as between 1 year and 3 months before the index date, was associated with an increased risk for aSAH. This trend was not found for other antihypertensives and was significant for amlodipine but not lisinopril.
The reasons are unclear, but “we trust the findings on lisinopril more,” Dr. Ruigrok said. “The findings on amlodipine may be due to confounding by indication, specifically caused by hypertension. Therefore, it is important to validate our findings in an independent research cohort, and we are in the process of doing so.”
The study’s second surprise was the antidiabetic drug metformin and cholesterol-lowering drug simvastatin were also associated with reduced aSAH risk, Dr. Ruigrok noted.
“We already knew from previous studies that diabetes and high cholesterol are protective factors for aSAH,” he said. “Our results suggest that perhaps not the conditions themselves are protective for aSAH but rather the drugs used to treat these conditions with are.”
The risk for a ruptured brain aneurysm among current users was 42% lower with metformin (OR, 0.58; 95% CI, 0.43-0.78), 22% lower with simvastatin (OR, 0.78; 95% CI, 0.64-0.96), and 45% lower with tamsulosin (OR, 0.55; 95% CI, 0.32-0.93).
An increased risk for aSAH was found only in current users of warfarin (OR, 1.35; 95% CI, 1.02-1.79), venlafaxine (OR, 1.67; 95% CI, 1.01-2.75), prochlorperazine (OR, 2.15; 95% CI, 1.45-3.18), and co-codamol (OR, 1.31; 95% CI, 1.10-1.56).
Other drugs within the classes of vitamin K antagonists, serotonin reuptake inhibitors, conventional antipsychotics, and compound analgesics did not show an association with aSAH.
The study was limited by the use of drug prescriptions, and patients may not take their drugs or use them incorrectly, noted the researchers, led by Jos P. Kanning, MSc, also with University Medical Center Utrecht.
The study was supported by the European Research Council. The authors reported no relevant financial relationships.

(aSAH), a drug-wide association study suggested.
The blood pressure drug lisinopril; the cholesterol drug simvastatin; the diabetes drug metformin; and the drug tamsulosin, prescribed for an enlarged prostate, were all associated with decreased aSAH risk, investigators found.
Conversely, four other drugs were associated with an increased risk for this severely morbid, often deadly, condition.
“The motivation for this study was the fact that we can currently prevent bleeding from intracranial aneurysms only by invasive treatment of those aneurysms with inherent complication risks,” said study investigator Ynte Ruigrok, MD, PhD, associate professor of neurology and neurosurgery, University Medical Center Utrecht, Utrecht, the Netherlands. “Drugs to reduce or eliminate this risk are not yet available. This study is a first step in identifying such drugs.”
The findings were published online in Neurology.
