Gout Increases the Risk for a Wide Range of Cardiovascular Diseases
People with gout are 58% more likely to develop cardiovascular disease (CVD), according to a new analysis. This increased risk was observed across 12 different cardiovascular conditions, including heart failure, arrhythmias, and valve diseases.
“These findings suggest that the organ damage associated with gout is likely to be much broader than originally thought,” Nathalie Conrad, PhD, senior author of the research and cardiovascular epidemiologist at KU Leuven, Leuven, Belgium, said in an email. This could be useful for future research on underlying biological mechanisms driving CVD risk in gout, she added.
While previous research has tied gout to increased cardiovascular risk, these studies “largely focused on coronary heart disease, stroke, and thromboembolic outcomes,” she explained, and have been smaller in size.
This new study included more than 862,000 individuals, which permitted researchers to investigate rarer CVD outcomes such as myocarditis and pericarditis.
For the study, researchers used electronic health records from the UK Clinical Practice Research Datalink, a primary care database that contains anonymized health data for about 22 million individuals. Using these data, they identified more than 152,600 individuals with gout. Patients included in the analysis were diagnosed between 2000 and 2017, younger than 80 years at diagnosis, and free of CVD for at least 12 months after their gout diagnosis.
Patients with gout were compared with nearly 710,000 controls, matched on demographic factors such as age, sex, and geographic region.
Researchers then investigated the incidence of 12 CVDs, including atherosclerotic diseases, degenerative and thromboembolic diseases, and arrythmias, between the two groups from January 1, 2000, to June 30, 2019.
The findings were published in the March 2024 issue of The Lancet Rheumatology. Overall, patients with gout were 58% more likely to develop any CVD than their matched comparators without gout. There was a higher disease incidence among patients with gout for each of the 12 conditions. This association was more pronounced in women (hazard ratio [HR], 1.88) than in men (HR, 1.49), and gout amplified the risk for CVD in younger individuals to a greater extent.
Individuals younger than 45 years with gout were more than twice as likely to develop CVD compared with similarly aged individuals without gout. For comparison, individuals aged 45-54 years with gout were 84% more likely to develop CVD, and individuals aged 55-64 years were 57% more likely to develop CVD than matched controls.
Conduction system disease had the highest incident risk (HR, 1.88), followed by heart failure and valve disease (HR, 1.85 for both).
Individuals with gout had higher rates of comorbidities than the controls, including hypertension, obesity, and dyslipidemia. Overall, CVD risk was slightly attenuated after adjustment for traditional CVD risk factors such as smoking, blood pressure, and body mass index but still significant: Patients with gout had a 31% higher risk for CVD than comparators.
This shows “that known CVD risk factors only explain part of the CVD risks seen in patients with gout,” Dr. Conrad said. Other factors such as inflammation and other disease activity factors could be at play, she explained, which would need to be explored in future research.
The study “shows the whole landscape” of CVD and gout, Michael H. Pillinger, MD, rheumatologist and professor of medicine, biochemistry, and molecular pharmacology at NYU Grossman School of Medicine in New York City, said in an interview. He was not involved with the research.
“Every possible cardiovascular disease that they could think of was something that gout patients had more of than the non-gout patients,” he added. “I think this is going to be a paper that gets cited a lot, at minimum when describing the background of risk when we look at gout patients.”
The study had some limitations, including that researchers were unable to account for how medications such as nonsteroidal anti-inflammatory drugs, corticosteroids, colchicine, or allopurinol may have affected the association between gout and CVD.
“This is because analyses of nonrandomized treatment can be confounded by indication, wherein it is difficult to differentiate the effects of the treatment from underlying disease severity,” the authors wrote.
There was also a large amount of missing data on blood pressure, body mass index, smoking status, and other health information relevant to cardiovascular risk, so sensitivity analyses adjusting for these factors “should be interpreted with caution,” they added.
Dr. Pillinger also noted that the rates of comorbidities in the gout study population were lower than what have been found in US study populations. For example, about 40% of patients with gout in the analysis had hypertension, while other studies have suggested higher rates of 60%-70%, he said. However, it’s not clear if these differences could have affected outcomes. He added that these limitations do not “in any way weaken [the authors’] conclusion.”
The findings call for better strategies to reduce CVD risk in patients with gout, Dr. Conrad noted.
“Further improvements could come from better recognition and intervention on CVD risk factors (eg, through lifestyle changes or drug therapies where they are indicated), as well as proactive screening for heart disease in patients with gout, which could allow early diagnosis and interventions to delay more severe outcomes,” she added.
This study was funded by Research Foundation Flanders. Dr. Conrad was funded by a personal fellowship from the Research Foundation Flanders and a European Society of Cardiology research grant. She received royalties from Oxford University Innovation. Four of Dr. Conrad’s eight coauthors also reported financial relationships with pharmaceutical companies. Dr. Pillinger served as a consultant to Amgen, Federation Bio, Fortress Biotech, and Scilex, and he holds an investigator-initiated grant from Hikma.

Health Gains of Exercise Greater in Women?
Women may gain greater health benefits from regular physical activity at equivalent or lower doses of activity, compared with men, according to data from more than 400,000 US adults.
Over two decades, with any regular physical activity, all-cause mortality risk was reduced by 24% in women vs 15% in men, and cardiovascular mortality risk was reduced by 36% and 14%, respectively, compared with inactivity, researchers found.
Participating in strength training exercises (vs not) was associated with a reduced risk for all-cause death of 19% in women and 11% men and reductions in cardiovascular death of 30% and 11%, respectively.
“Women have historically and statistically lagged behind men in engaging in meaningful exercise,” co–lead author Martha Gulati, MD, with the Smidt Heart Institute at Cedars-Sinai, Los Angeles, said in a statement. “The beauty of this study is learning that women can get more out of each minute of moderate to vigorous activity than men do. It’s an incentivizing notion that we hope women will take to heart.”
The study was published online February 19 in the Journal of the American College of Cardiology.
Sex-Specific Exercise Advice?
The findings are based on leisure-time physical activity data collected over roughly 20 years via the National Health Interview Survey for 412,413 US adults aged 27-61 years. During roughly 4.9 million person-years of follow-up, there were 39,935 all-cause deaths and 11,670 cardiovascular deaths.
Both men and women achieved a peak survival benefit at 300 minutes of weekly moderate to vigorous aerobic physical activity. But the mortality reduction was substantially greater in women than in men for the same amount of regular exercise (24% vs 18%).
Similarly, for any given dose of physical activity leading up to 300 minutes per week, women derived proportionately greater survival benefits than did men, the authors reported.
“Importantly, the greater magnitude of physical activity-related survival benefit in women than men was consistently found across varied measures and types of physical activity including frequency, duration per session, and intensity of aerobic physical activity, as well as frequency of muscle strengthening activities,” they wrote.
They say multiple factors, including variations in anatomy and physiology, may account for the differences in outcomes between men and women. For example, compared with men, women may use more respiratory, metabolic, and strength demands to conduct the same movement and in turn, reap greater health benefits.
The study also showed only 33% of women and 43% of men regularly engaged in aerobic physical activity, whereas only 20% of women and 28% of men completed a weekly strength training session.
“We hope this study will help everyone, especially women, understand they are poised to gain tremendous benefits from exercise,” senior author Susan Cheng, MD, with the Smidt Heart Institute at Cedars-Sinai, Los Angeles, said in a statement.
In an accompanying editorial, Wael A. Jaber, MD, and Erika Hutt, MD, from Cleveland Clinic Ohio, wrote that this analysis “brings us one step farther in gaining insights into the role and influence of physiological responses to exercise with a sex-specific lens.”
The study is “well designed and adds important information to the body of literature that can potentially close the gender gap and optimize sex-specific physical activity recommendations by policy makers and societal guidelines,” they wrote.
“This study emphasizes that there is no singular approach for exercise. A person’s physical activity needs and goals may change based on their age, health status, and schedule — but the value of any type of exercise is irrefutable,” Eric J. Shiroma, ScD, with the National Heart, Lung, and Blood Institute, said in a statement.
The study was supported in part by grants from the National Institutes of Health. The authors and editorial writers have declared no relevant conflicts of interest.

Adding Antithrombotic to tPA Does Not Improve Stroke Outcome
PHOENIX — , results of new research show.
“Ultimately, we found no benefit for either medication added to standard-of-care thrombolysis in terms of improving stroke outcomes,” said lead study author Opeolu M. Adeoye, MD, professor of emergency medicine and department chair, Washington University School of Medicine, St. Louis, Missouri.
The results were surprising and disappointing for Dr. Adeoye. “We went into the trial hopeful and thinking we would be able to benefit patients in reducing disability from stroke,” he said.
The Multi-Arm Optimization of Stroke Thrombolysis (MOST) trial was stopped early because of futility following recommendations from the data and safety monitoring board.
The findings were presented at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
A thrombolytic drug alone doesn’t help all patients, particularly those with larger clots. “Clots can open; they can reform; they can re-occlude, etc.,” said another author, Andrew D. Barreto, MD, associate professor, Department of Neurology, University of Texas Health Science Center, Houston. “The thought was that adding additional medications that thin the blood, like argatroban or eptifibatide, would amplify the effects of the clot-busting drug.”
Indeed, this approach has had success in cardiology in terms of blood vessel opening, said Dr. Adeoye, adding that some preclinical data suggest that antithrombotic drugs may be neuroprotective.
Six phase 2 studies going back over a dozen years suggested that these drugs are safe in stroke patients. Although these studies weren’t powered for efficacy, “we did see a signal that adding them would be better than just the clot-busting drug alone.” These findings prompted the current phase 3 trial, said Dr. Barreto.
The three-arm, single-blind MOST trial included 514 adult patients with acute ischemic stroke and a National Institutes of Health Stroke Scale (NIHSS) score of 6 or greater at 57 US centers. In the study cohort the mean age was about 68 years, 70% White/25% Black, and with about equal numbers of female and male patients.
All received standard stroke care including thrombolysis within 3 hours of symptom onset. Initially, researchers used intravenous alteplase (0.9 mg/kg), but as the standard of care changed over time, they began using tenecteplase (0.25 mg/kg).
Study patients were also randomly assigned to receive placebo or either argatroban (100 mcg/kg bolus followed by 3 mcg/kg per minute for 12 hours) or eptifibatide (135 mcg/kg bolus followed by 0.75 mcg/kg/min infusion for 2 hours). These treatments were initiated within 75 minutes of thrombolysis.
Two Different Mechanisms
The drugs have different mechanisms of action. Argatroban is an anticoagulant, a direct inhibitor of thrombin, while the antiplatelet eptifibatide blocks the glycoprotein IIb/IIIa receptor and was specifically developed to ensure rapid inhibition of platelet aggregation.
Patients could also receive endovascular thrombectomy as part of their usual care. In this study, about 44% of patients received this treatment.
The primary endpoint was 90-day utility weighted modified Rankin Scale (uw-mRS) scores, where the worst outcome is 0 and the best outcome is 10.
The study used a response-adaptive randomization design, where the randomization switches from a drug that doesn’t appear to have a chance of working to the arm more likely to be beneficial.
Of the 514 patients, the analysis included 228 in the placebo, 59 in the argatroban, and 227 in eptifibatide groups. Of the total, 421 completed the study.
The mean 90-day uw-mRS was 6.8 in the placebo group, 5.2 in the argatroban group, and 6.3 in the eptifibatide group.
The probability of argatroban being better than placebo was 0.2%; the probability of eptifibatide being better than placebo was 0.9%. The futility threshold was enrollment of 500 and less than a 20% chance of benefit, thus the decision to stop the trial.
In all subgroup analyses, which looked at age, stroke severity, the two thrombolytic drugs, and use of endovascular therapy, “we didn’t really see much of a signal that would suggest that’s the group we would need to be testing further,” said Dr. Barreto.
No Increased ICH Risk
The primary safety outcome was symptomatic intracranial hemorrhage within 36 hours of randomization. The researchers found no significant increase in rates of this outcome.
The argatroban cohort had significantly lower odds of favorable outcomes compared with placebo, noted Dr. Adeoye. For example, it had more all-cause deaths, although none were related to the study drug.
Speculating on why the intervention didn’t work, Dr. Barreto pointed to changes in standard of care between the earlier trials and the current one, including the incorporation of endovascular therapy and switch to tenecteplase.
Although the results were disappointing, Dr. Adeoye sees a bright side. “What we’re very proud of, and excited about, is the fact that we have a definitive answer on these two drugs, and we did it in one trial as opposed to sequential, separate ongoing trials.”
But he stressed that more work needs to be done, especially given that even with endovascular therapy, half of stroke patients don’t achieve independence.
“In this trial, we established that argatroban and eptifibatide added to thrombolysis did not work, but that doesn’t address the fact that we need to continue to see what we can do to improve the total proportion of stroke patients who, after our treatments, are functionally independent 90 days after the stroke.”
Down the Rabbit Hole
Commenting on the research, Larry B. Goldstein, MD, professor and chair, Department of Neurology, University of Kentucky, Lexington, praised the study’s adaptive design, noted that the hypothesis the study was based on was “reasonable” given the concern about additional thromboses, and found the results useful.
“The goal is not only to see what works but also what doesn’t work so we don’t go down that rabbit hole.”
He also pointed out that because the two blood-thinning drugs studied have very different mechanisms of action, it’s unlikely that another antithrombotic would add benefit to thrombolysis, “but you never say never.”

PHOENIX — , results of new research show.
“Ultimately, we found no benefit for either medication added to standard-of-care thrombolysis in terms of improving stroke outcomes,” said lead study author Opeolu M. Adeoye, MD, professor of emergency medicine and department chair, Washington University School of Medicine, St. Louis, Missouri.
The results were surprising and disappointing for Dr. Adeoye. “We went into the trial hopeful and thinking we would be able to benefit patients in reducing disability from stroke,” he said.
The Multi-Arm Optimization of Stroke Thrombolysis (MOST) trial was stopped early because of futility following recommendations from the data and safety monitoring board.
The findings were presented at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
A thrombolytic drug alone doesn’t help all patients, particularly those with larger clots. “Clots can open; they can reform; they can re-occlude, etc.,” said another author, Andrew D. Barreto, MD, associate professor, Department of Neurology, University of Texas Health Science Center, Houston. “The thought was that adding additional medications that thin the blood, like argatroban or eptifibatide, would amplify the effects of the clot-busting drug.”
Indeed, this approach has had success in cardiology in terms of blood vessel opening, said Dr. Adeoye, adding that some preclinical data suggest that antithrombotic drugs may be neuroprotective.
Six phase 2 studies going back over a dozen years suggested that these drugs are safe in stroke patients. Although these studies weren’t powered for efficacy, “we did see a signal that adding them would be better than just the clot-busting drug alone.” These findings prompted the current phase 3 trial, said Dr. Barreto.
The three-arm, single-blind MOST trial included 514 adult patients with acute ischemic stroke and a National Institutes of Health Stroke Scale (NIHSS) score of 6 or greater at 57 US centers. In the study cohort the mean age was about 68 years, 70% White/25% Black, and with about equal numbers of female and male patients.
All received standard stroke care including thrombolysis within 3 hours of symptom onset. Initially, researchers used intravenous alteplase (0.9 mg/kg), but as the standard of care changed over time, they began using tenecteplase (0.25 mg/kg).
Study patients were also randomly assigned to receive placebo or either argatroban (100 mcg/kg bolus followed by 3 mcg/kg per minute for 12 hours) or eptifibatide (135 mcg/kg bolus followed by 0.75 mcg/kg/min infusion for 2 hours). These treatments were initiated within 75 minutes of thrombolysis.
Two Different Mechanisms
The drugs have different mechanisms of action. Argatroban is an anticoagulant, a direct inhibitor of thrombin, while the antiplatelet eptifibatide blocks the glycoprotein IIb/IIIa receptor and was specifically developed to ensure rapid inhibition of platelet aggregation.
Patients could also receive endovascular thrombectomy as part of their usual care. In this study, about 44% of patients received this treatment.
The primary endpoint was 90-day utility weighted modified Rankin Scale (uw-mRS) scores, where the worst outcome is 0 and the best outcome is 10.
The study used a response-adaptive randomization design, where the randomization switches from a drug that doesn’t appear to have a chance of working to the arm more likely to be beneficial.
Of the 514 patients, the analysis included 228 in the placebo, 59 in the argatroban, and 227 in eptifibatide groups. Of the total, 421 completed the study.
The mean 90-day uw-mRS was 6.8 in the placebo group, 5.2 in the argatroban group, and 6.3 in the eptifibatide group.
The probability of argatroban being better than placebo was 0.2%; the probability of eptifibatide being better than placebo was 0.9%. The futility threshold was enrollment of 500 and less than a 20% chance of benefit, thus the decision to stop the trial.
In all subgroup analyses, which looked at age, stroke severity, the two thrombolytic drugs, and use of endovascular therapy, “we didn’t really see much of a signal that would suggest that’s the group we would need to be testing further,” said Dr. Barreto.
No Increased ICH Risk
The primary safety outcome was symptomatic intracranial hemorrhage within 36 hours of randomization. The researchers found no significant increase in rates of this outcome.
The argatroban cohort had significantly lower odds of favorable outcomes compared with placebo, noted Dr. Adeoye. For example, it had more all-cause deaths, although none were related to the study drug.
Speculating on why the intervention didn’t work, Dr. Barreto pointed to changes in standard of care between the earlier trials and the current one, including the incorporation of endovascular therapy and switch to tenecteplase.
Although the results were disappointing, Dr. Adeoye sees a bright side. “What we’re very proud of, and excited about, is the fact that we have a definitive answer on these two drugs, and we did it in one trial as opposed to sequential, separate ongoing trials.”
But he stressed that more work needs to be done, especially given that even with endovascular therapy, half of stroke patients don’t achieve independence.
“In this trial, we established that argatroban and eptifibatide added to thrombolysis did not work, but that doesn’t address the fact that we need to continue to see what we can do to improve the total proportion of stroke patients who, after our treatments, are functionally independent 90 days after the stroke.”
Down the Rabbit Hole
Commenting on the research, Larry B. Goldstein, MD, professor and chair, Department of Neurology, University of Kentucky, Lexington, praised the study’s adaptive design, noted that the hypothesis the study was based on was “reasonable” given the concern about additional thromboses, and found the results useful.
“The goal is not only to see what works but also what doesn’t work so we don’t go down that rabbit hole.”
He also pointed out that because the two blood-thinning drugs studied have very different mechanisms of action, it’s unlikely that another antithrombotic would add benefit to thrombolysis, “but you never say never.”

Expanded Window of Stroke Thrombectomy With Simpler Imaging
PHOENIX — Thrombectomy is generally beneficial for patients from a low-income population who have a large vessel occlusion stroke presenting in the later time window and who can be identified as suitable for treatment without the need for advanced and costly imaging, a new Brazilian trial has shown.
“The RESILIENT-Extend trial is the first major study of thrombectomy in the late time window (8-24 h) conducted outside first-world countries and shows the procedure also has benefit in a lower socioeconomic status population without the need for costly imaging equipment,” said lead investigator Raul G. Nogueira, MD.
“The trial expands the treatment window for thrombectomy globally with simplified selection criteria based on non-contrast CT, potentially altering current guidelines,” Dr. Nogueira said.
However, there were some caveats that need to be considered; in particular, a lack of benefit with thrombectomy in older patients (over 68 years of age), which Dr. Nogueira believes is a reflection of the particular population enrolled in this study. Specifically, he suggested that older age in this low socioeconomic status population is a surrogate for frailty, and the study may have identified frailty as a factor that correlates with reduced or lack of benefit of thrombectomy.
Dr. Nogueira, who is a professor of neurology and neurosurgery at the University of Pittsburgh, and Sheila Martins, MD, a professor of neurology at Hospital de Clinicas Porto Alegre in Brazil, presented the RESILIENT-Extend results at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
Dr. Nogueira explained that the lack of available advanced imaging techniques is a major challenge for implementing endovascular therapy in an extended time window, especially in lower-income countries.
“Our main objective was to see if we could remove the need for advanced imaging to select patients with large vessel occlusion stroke in the late time window (8-24 h) for thrombectomy,” he said. “In this way, our trial overlaps somewhat with the MR CLEAN-LATE Trial conducted in the Netherlands, although the two trials were conducted in very different socioeconomic populations.”
The RESILIENT-Extend trial was conducted in the public health service of Brazil and involved a different population of people than have been included in other thrombectomy trials, which have mostly been conducted in first-world countries.
“The public health system in Brazil is not well-resourced and tends to care for patients at lower socioeconomic levels. These patients are fundamentally different from the average patients in the first-world recruited into most other thrombectomy trials,” Dr. Nogueira noted.
The trial enrolled 245 patients with a large vessel occlusion stroke within 8-24 hours of last known well. Patients were included who had a mismatch between the clinical severity as shown by the National Institutes of Health Stroke Scale (NIHSS) score and the stroke burden on imaging as measured by ASPECTS scores.
They had to have relatively high NIHSS scores (8 or more) showing more severe strokes but also a high ASPECTS score (5-10) excluding patients with large areas of ischemic brain. There was also a sliding scale that adjusted for age to avoid enrolling elderly patients with large strokes.
These patients were identified exclusively using non-contrast CT and CT angiography imaging.
The median age of patients included was 62-63 years. Dr. Nogueira pointed out that patients were slightly younger than seen in other thrombectomy trials, perhaps because in lower-middle-income countries strokes occur at a younger age. They also have a higher case fatality rate.
The median baseline NIHSS score was 16, and the median ASPECTS score was 7-8.
The median time to treatment was 12.5 hours, which is similar to other late window thrombectomy trials.
Conflicting Results on Shift Analysis
The primary outcome was a shift analysis of the modified Rankin Scale (mRS) disability score at 90 days.
This showed a bidirectional result, with thrombectomy increasing the chances of a good or excellent outcome (mRS, 0-3), but there was also a nonsignificant increased risk for a bad outcome (mRS, 5-6).
“This bidirectional result prevents a common odds ratio from being calculated, so the primary endpoint is not applicable,” Dr. Nogueira reported.
The researchers therefore used the secondary outcomes as the main results of the study.
These showed that the number of patients achieving a good outcome (mRS, 0-2) was significantly increased with thrombectomy (25% vs. 14%, adjusted odds ratio, 2.56; P = .012).
The number of patients achieving an excellent outcome (mRS, 0-1) was also significantly increased.
But these increases in good outcomes came at the cost of some patients having an increased risk for severe disability or death (mRS, 5-6).
The odds ratio for an mRS of 0-4 versus 5-6 was 0.71, and for an mRS of 0-5 versus 6, the odds ratio was 0.58. Both these results were nonsignificant.
Another anomaly in the RESILIENT-Extend trial was the observation of no benefit of thrombectomy seen in older patients.
“In general, trials of thrombectomy in the first world have shown a greater treatment effect in older patients, but this was not seen in our trial, where older patients (over 68 years) did not derive any benefit from the procedure,” Dr. Nogueira noted.
A similar observation was also seen in the first RESILIENT trial in patients treated within 8 hours of stroke onset, which was also conducted in Brazil, leading to the suggestion that it is related to the patient population included.
“In the Brazilian public health service, older patients are very vulnerable and frail. They are different to older patients in first world countries. It appears they may be too fragile to withstand the thrombectomy process,” Dr. Nogueira said.
Frailty: A Ceiling Effect?
Results from the two RESILIENT trials give a word of caution to the thrombectomy field, Dr. Nogueira said.
“This procedure was initially thought suitable only for patients with small core strokes, but we now have a series of trials showing benefit of thrombectomy in large core strokes as well,” Dr. Nogueira said. “We have started to believe that this intervention will benefit almost all patients with large vessel occlusion stroke everywhere around the world, but our data suggest that we have to consider the specific populations that we are serving and that factors such as socioeconomic status and frailty have to be taken into account.
“Both the RESILIENT trials have shown that thrombectomy does not appear to be suitable for older patients, over 68-70 years of age, in the public health service in Brazil,” he noted. “In this population, a patient aged 70 can be quite different to a patient of the same age in a first-world country. I think in our population, an age of over 68-70 is a surrogate for frailty, which will not be the case in first-world countries. In this regard, I think we have found a ceiling effect for benefit of thrombectomy, which is frailty.”
Dr. Nogueira speculated that the bidirectional effect on the mRS shift analysis may also have been caused by the frailty of some of the patients.
“What the results may be showing is that for most of the population, there is a benefit of thrombectomy, but for some patients, possibly the most frail, then the procedure can be too overwhelming for them. But the suggestion of harm was not significant, so this observation could have also just been the play of chance,” he added.
Interpreting the Findings
Commenting on the RESILIENT-Extend study results, Michael Hill, MD, professor of neurology at the University of Calgary, Canada, pointed out that there was an absolute benefit of 11.1% on the mRS of 0-2 outcome but a similar signal of harm, with a 10.2% increase in mortality in the thrombectomy group, although that was not statistically significant.
“This signal of harm appears not to be due to an increase in intracranial hemorrhage or procedural mishap,” he said. “It is unclear why there were more deaths; the overall trial numbers are small enough that this could be a chance finding.”
Dr. Hill also noted that the absolute proportion of patients achieving an independent functional outcome was 50% less than in the DAWN trial of thrombectomy in the extended window. “This tells us that the patients selected for inclusion into RESILIENT-Extend were physiologically different from those in DAWN,” he said.
Also commenting on the study, Amrou Sarraj, MD, professor of neurology at University Hospitals Cleveland Medical Center–Case Western Reserve University in Cleveland, said: “The RESILIENT-Extend investigators should be congratulated for the successful conduct of the trial and providing evidence of benefit of thrombectomy procedure with simplified neuroimaging protocol using CT and CTA in resource-limited settings. These findings will help support extending the access to thrombectomy in areas without availability of advanced imaging.”
He said the bidirectional effect on the primary endpoint and the positive interaction between age and thrombectomy treatment effect warranted further investigation.
The RESILIENT-Extend trial was sponsored by the Brazilian Ministry of Health.

The primary outcome was a shift analysis of the modified Rankin Scale (mRS) disability score at 90 days.
This showed a bidirectional result, with thrombectomy increasing the chances of a good or excellent outcome (mRS, 0-3), but there was also a nonsignificant increased risk for a bad outcome (mRS, 5-6).
“This bidirectional result prevents a common odds ratio from being calculated, so the primary endpoint is not applicable,” Dr. Nogueira reported.
The researchers therefore used the secondary outcomes as the main results of the study.
These showed that the number of patients achieving a good outcome (mRS, 0-2) was significantly increased with thrombectomy (25% vs. 14%, adjusted odds ratio, 2.56; P = .012).
The number of patients achieving an excellent outcome (mRS, 0-1) was also significantly increased.
But these increases in good outcomes came at the cost of some patients having an increased risk for severe disability or death (mRS, 5-6).
The odds ratio for an mRS of 0-4 versus 5-6 was 0.71, and for an mRS of 0-5 versus 6, the odds ratio was 0.58. Both these results were nonsignificant.
Another anomaly in the RESILIENT-Extend trial was the observation of no benefit of thrombectomy seen in older patients.
“In general, trials of thrombectomy in the first world have shown a greater treatment effect in older patients, but this was not seen in our trial, where older patients (over 68 years) did not derive any benefit from the procedure,” Dr. Nogueira noted.
A similar observation was also seen in the first RESILIENT trial in patients treated within 8 hours of stroke onset, which was also conducted in Brazil, leading to the suggestion that it is related to the patient population included.
“In the Brazilian public health service, older patients are very vulnerable and frail. They are different to older patients in first world countries. It appears they may be too fragile to withstand the thrombectomy process,” Dr. Nogueira said.
Frailty: A Ceiling Effect?
Results from the two RESILIENT trials give a word of caution to the thrombectomy field, Dr. Nogueira said.
“This procedure was initially thought suitable only for patients with small core strokes, but we now have a series of trials showing benefit of thrombectomy in large core strokes as well,” Dr. Nogueira said. “We have started to believe that this intervention will benefit almost all patients with large vessel occlusion stroke everywhere around the world, but our data suggest that we have to consider the specific populations that we are serving and that factors such as socioeconomic status and frailty have to be taken into account.
“Both the RESILIENT trials have shown that thrombectomy does not appear to be suitable for older patients, over 68-70 years of age, in the public health service in Brazil,” he noted. “In this population, a patient aged 70 can be quite different to a patient of the same age in a first-world country. I think in our population, an age of over 68-70 is a surrogate for frailty, which will not be the case in first-world countries. In this regard, I think we have found a ceiling effect for benefit of thrombectomy, which is frailty.”
Dr. Nogueira speculated that the bidirectional effect on the mRS shift analysis may also have been caused by the frailty of some of the patients.
“What the results may be showing is that for most of the population, there is a benefit of thrombectomy, but for some patients, possibly the most frail, then the procedure can be too overwhelming for them. But the suggestion of harm was not significant, so this observation could have also just been the play of chance,” he added.
Interpreting the Findings
Commenting on the RESILIENT-Extend study results, Michael Hill, MD, professor of neurology at the University of Calgary, Canada, pointed out that there was an absolute benefit of 11.1% on the mRS of 0-2 outcome but a similar signal of harm, with a 10.2% increase in mortality in the thrombectomy group, although that was not statistically significant.
“This signal of harm appears not to be due to an increase in intracranial hemorrhage or procedural mishap,” he said. “It is unclear why there were more deaths; the overall trial numbers are small enough that this could be a chance finding.”
Dr. Hill also noted that the absolute proportion of patients achieving an independent functional outcome was 50% less than in the DAWN trial of thrombectomy in the extended window. “This tells us that the patients selected for inclusion into RESILIENT-Extend were physiologically different from those in DAWN,” he said.
Also commenting on the study, Amrou Sarraj, MD, professor of neurology at University Hospitals Cleveland Medical Center–Case Western Reserve University in Cleveland, said: “The RESILIENT-Extend investigators should be congratulated for the successful conduct of the trial and providing evidence of benefit of thrombectomy procedure with simplified neuroimaging protocol using CT and CTA in resource-limited settings. These findings will help support extending the access to thrombectomy in areas without availability of advanced imaging.”
He said the bidirectional effect on the primary endpoint and the positive interaction between age and thrombectomy treatment effect warranted further investigation.
The RESILIENT-Extend trial was sponsored by the Brazilian Ministry of Health.

Hypertension Before Age 35 Tied to Triple Stroke Risk in Midlife
PHOENIX — , new observational data suggest. The Black Women’s Health Study, which has followed 59,000 participants in the United States since 1990s, also showed that those who develop hypertension before age 45 have twice the risk of suffering a stroke.
“The really concerning thing about this data is the high proportion of young Black women who had high blood pressure and are suffering strokes relatively early in life,” said the study’s lead author, Hugo J. Aparicio, MD, associate professor of neurology at Boston University Chobanian & Avedisian School of Medicine, Boston. “This can lead to a burden of disability in relatively young women who may be at the prime of their life, pursuing careers, and looking after family.”
Dr. Aparicio presented the data at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
He explained that while there has been good progress in reducing stroke rates in older people over the past decades, there is a concerning observation from multiple datasets showing that stroke rates in midlife have been plateauing or even increasing in recent years.
“For Black women specifically, there is a concern, as we know this group has higher rates of raised blood pressure and stroke overall,” said Dr. Aparicio. “We were interested in looking at whether the onset of hypertension at an earlier age in this group is one of the reasons for the increased stroke risk in midlife.”
A Large Study Cohort
The researchers analyzed data from the Black Women’s Health Study; the baseline year for this analysis, which included 46,754 stroke-free participants younger than age 65 (mean age, 42 years), was the 1999 questionnaire.
Both history of hypertension — defined as physician-diagnosed hypertension with the use of an antihypertensive medication — and stroke occurrence were determined by self-report. It has been shown in previous studies that these self-reported data on incidence of hypertension in this dataset are highly reliable, Dr. Aparicio noted.
At baseline, 10.5% of participants aged 45-64 years had hypertension. Stroke occurred in 3.2% of individuals over a mean follow-up of 17 years.
Black women with hypertension before age 45 had a higher risk for midlife stroke (hazard ratio [HR], 2.23; 95% confidence interval [CI], 1.79-2.78), after adjustment for age, neighborhood socioeconomic status, residence in the Stroke Belt, smoking, body mass index, and diabetes than women with no history of hypertension.
The risk was also increased with hypertension at midlife ages 45-64 years (HR, 1.69; 95% CI, 1.47-1.95) and was highest among those with hypertension at ages 24-34 years (HR, 3.15; 95% CI, 1.92-5.16).
“Our results show that among young Black women, those with hypertension have a much higher stroke risk than those without hypertension, even if they are taking antihypertensive medication,” Dr. Aparicio said. “This underscores how potent hypertension is as a risk factor for stroke.”
He concluded that both individuals and doctors need to realize that hypertension and stroke are not problems of the elderly exclusively.
“These are conditions that need to be addressed very early in life. This is even more important for Black women, as they are a high-risk group. They need to pay attention to blood pressure numbers early in life — ideally from adolescence — to catch levels before they become too elevated,” Dr. Aparicio said.
“We also need to address lifestyle changes including diet, physical activity, sleep habits, and address other cardiovascular risk factors such as cholesterol and body mass index, so we can prevent strokes from occurring,” he added. “At the policy level, we need to advocate, provide and fund primary prevention measures, and enable earlier screening and better treatment.”
The Role of Psychosocial Stressors
Commenting on the study, the American Heart Association immediate past president, Michelle A. Albert, MD, professor of medicine at the University of California, San Francisco, emphasized the importance of regular primary care appointments to screen for high blood pressure and other cardiovascular risk factors.
She pointed out that one of the contributing factors that may increase the risk for Black women is their disproportionate experience of psychosocial stressors and chronic cumulative stress.
This could include stress related to financial issues, racism and other forms of bias, the neighborhood environment, and having to take care of multiple generations of family with limited resources.
“These are some of the things that are less talked about as going into the heightened risk for many cardiovascular risk factors, including hypertension, very early in life for Black women that we need to bring to the forefront of conversations,” Dr. Albert said.
“These stressors not only impact hypertension onset but also they impact one’s ability to be able to seek help, and once the help is sought, to be able to sustain the therapies recommended and the interventions recommended,” she added.
The authors reported no relevant disclosures.

AHA: Urgent Need To Reduce Maternal Postpartum CVD Risk
Complications during pregnancy may be a wake-up call pointing to a higher risk for cardiovascular (CVD) and other diseases later in life. Therefore, the postpartum and interpregnancy periods are opportune windows for reducing CVD susceptibility and providing preventive care, especially for mothers with a history of adverse pregnancy outcomes (APOs). To that end, the American Heart Association recently released a scientific statement in Circulation outlining pregnancy-related CVD risks and reviewing evidence for preventive lifestyle strategies based on the AHA’s Life’s Essential 8 recommendations.
The Life’s Essential 8 encompass healthy eating, sleeping, and activity patterns; controlling weight, blood pressure, cholesterol, and blood sugar; and avoiding tobacco use.
“The motivation behind this statement was that complications in pregnancy are becoming more common and we now have more understanding that these serve as important risk factors for heart disease later in life,” said Jennifer Lewey, MD, MPH, director of the Penn Women’s Cardiovascular Health Program and an assistant professor of medicine at the University of Pennsylvania Perelman School of Medicine in Philadelphia.
“These risk factors are underrecognized and underappreciated. Clinicians don’t feel comfortable counseling their patients about how to reduce their cardiovascular disease risk,” Dr. Lewey, chair of the AHA writing group, said in an interview.
“So we thought this was the perfect time to highlight what we know and don’t know about how to care for this population,” she said.
APOs predispose mothers to heart disease and other long-term complications, including heart failure, stroke, chronic kidney disease, and vascular dementia. “Pregnancy is a significant stress on the body, and APOs such as preeclampsia can lead to vascular changes in the blood vessels and structural changes to the heart that can persist long term,” Dr. Lewey explained. Reduced maternal physical activity and unshed weight can compound the problem.
Varying by race and ethnicity, the proportion of mothers experiencing pregnancy complications, such as high blood pressure, gestational diabetes, and/or preterm birth is estimated at 10%-20%, the statement authors noted. These complications may serve as a wake-up call to young mothers.
The AHA panel believes that identifying at-risk women at younger ages will enable prevention through lifestyle changes and timely treatment. Little is known, however about what specific care may best reduce long-term CVD risk in women who had pregnancy complications, Dr. Lewey said. While randomized clinical trials have yet to evaluate the effects of postpartum interventions on CVD outcomes, the need for strategies supported by rigorous evidence is clear. “In particular, the fourth trimester, defined as the 12 weeks after delivery, is an optimal time to engage postpartum individuals in care to reduce maternal morbidity and improve care transitions,” the AHA group wrote.
An earlier AHA statement in 2021 recommended frequent cardiac risk factor screening in the first year postpartum at 6 and 12 weeks and again at 6 and 12 months, with appropriate transition from postpartum to longitudinal primary care around the 8- to 12-week mark.
Among the current statement’s findings: High blood pressure is the most prevalent cardiovascular condition during pregnancy, and the last two decades have seen a 25% increase in preeclampsia.
Hypertension during pregnancy carries a two- to fourfold higher risk of chronic hypertension within 2-7 years.
Women with one or more APOs experience heart attack and stroke at younger ages. Commenting on the statement but not involved in it, internist Natalie A. Cameron, MD, a primary and preventive care physician at Northwestern Medicine in Chicago, said, “This statement will be very helpful for physicians from a primary care perspective, especially since in internal medicine we don’t standardly receive education in cardiovascular health in the context of pregnancy and the first year postpartum.”
Dr. Cameron also noted that new research suggests the mother’s cardiovascular health during pregnancy can affect the child’s health through adolescence. “There’s a potential intergenerational effect and there may even be some programming and changes to the offspring in utero related to maternal lifestyle factors.”
While the postpartum period would seem like an opportune time to piggyback postpartum visits with infant wellness checkups, “the fact is that, in the U.S., many mothers are lost to care after delivery,” Dr. Lewey said. “But it’s essential to ensure transition to postpartum care.”
According to Dr. Cameron, physicians should be aware of the risk factor data and educate their pregnant and postpartum patients about reducing risk factors. “As I like to say, ‘If you’re going to take care of others, you need to take care of yourself first.’ ” While this statement may be a good starting point, future trials are needed to improve screening for subclinical CVD in individuals with APOs before symptom onset, the statement authors wrote.
This scientific statement was prepared on behalf of the American Heart Association. Dr. Lewey and several coauthors reported research funding from various agencies within the National Institutes of Health. Dr. Brown reported research funding from a cy-près court settlement with Wyeth. Dr. Cameron had no competing interests relevant to her comments.

Tirofiban Reduces Early Neurologic Deterioration After Stroke
Intravenous (IV) administration of the antiplatelet agent tirofiban for 72 hours was associated with a reduction in early neurologic deterioration compared with oral aspirin therapy in patients with acute ischemic stroke, in the randomized TREND trial.
The results were presented at the International Stroke Conference 2024, held on February 7-9 in Phoenix, Arizona.
Lead author Zhao Wenbo, MD, Xuanwu Hospital, Beijing, China, noted that neurologic deterioration, characterized by a sudden onset and quick peak of neurologic deficits, is a common phenomenon in acute ischemic stroke and is strongly associated with poor clinical outcomes.
Ischemic stroke progression is the main cause of neurologic deterioration, especially during the first few days after onset, Dr. Wenbo said. , but administering oral antiplatelet agents can be difficult because of dysphagia, he reported.
The TREND trial was conducted to investigate whether IV tirofiban could prevent early neurologic deterioration without increasing the risk for symptomatic intracerebral hemorrhage in acute ischemic stroke.
The study included 426 patients with acute ischemic stroke within 24 hours of symptom onset who had a neurologic deficit attributed to focal cerebral ischemia and a National Institutes of Health Stroke Scale (NIHSS) score between 4 and 20 points and who were not treated with thrombolysis or endovascular thrombectomy. Patients with cardioembolic stroke were also excluded.
Patients were a median of 10-12 hours from symptom onset and had a baseline NIHSS score of 5.
They were randomized to IV tirofiban or oral aspirin for 72 hours. All patients were then continued on oral antiplatelet therapy.
The primary efficacy outcome was neurologic deterioration within 72 hours after randomization, defined as an increase in NIHSS score of 4 points or more.
This occurred in nine patients (4.2%) in the tirofiban group vs 28 (13.2%) in the control group (relative risk, 0.32; 95% CI, 0.15-0.66; P = .002).
A consistent benefit of IV tirofiban was seen across all subgroups.
The secondary endpoint of neurologic deterioration within 72 hours after randomization, defined as an increase of NIHSS score of 2 points or more, was also significantly reduced. This occurred in 11.7% of the tirofiban group vs 23.6% of the aspirin group (RR, 0.49; 95% CI, 0.32-0.75; P = .001).
An excellent outcome on the modified Rankin Scale (mRS) disability score (mRS, 0-1) at 90 days was seen in 75% of tirofiban vs 68% of aspirin patients, a nonsignificant difference.
A good outcome (mRS, 0-2) occurred in 89% of tirofiban vs 86% of aspirin patients, again a nonsignificant difference.
There were no symptomatic intracerebral hemorrhages within 72 hours after randomization (the primary safety endpoint) in either group, and the incidence of systemic bleeding also did not differ significantly between the groups.
Dr. Wenbo concluded that further randomized clinical trials are needed to determine the efficacy of tirofiban on functional outcomes.
‘Promising Results’
Commenting on the study for this news organization, conference chair, Tudor Jovin, MD, Cooper Medical School of Rowan University, Camden, New Jersey, and vice-chair, Lauren Sansing, MD, Yale School of Medicine, New Haven, Connecticut, both said they thought the results were promising.
“This study didn’t show any long-term outcome benefit, but this was a smaller study, and the results need to be replicated in a larger study with sufficient power to look at longer-term outcomes,” Sansing noted. “But we don’t have anything better than aspirin at present for these patients, so it’s exciting that there may be something in the pipeline for this group.”
Dr. Jovin pointed out that the TREND trial selected patients on the cause of their stroke, in line with the practice of precision medicine.
“By excluding patients who received thrombolysis or thrombectomy and those who had cardioembolic strokes, we are left with a population who we don’t have many treatment options for,” he said. “These are patients with smaller or moderate strokes who may arrive too late for thrombolysis. It would be great to be able to do something more than just aspirin for these patients.”
Dr. Jovin noted that the study was underpowered to show long-term benefits, but there were some promising trends.
“It stands to reason that if neurologic function does not get worse in the early hours and days after stroke, then the long-term outcomes are likely to be better,” he noted. “But this needs to be confirmed in larger trials.”
Interestingly, another study, the MOST trial, also presented at the ISC-24 meeting, showed no benefit with the IV antithrombotic agents argatroban or eptifibatide on 90-day functional outcomes when added to thrombolysis in acute ischemic stroke.
Dr. Jovin pointed out that the MOST and TREND trials included different populations of patients — the MOST patients received thrombolysis, while the TREND patients did not. And in the MOST trial, about half the patients had a large vessel occlusion and underwent thrombectomy, whereas these patients were excluded in TREND.
Dr. Sansing added that patients in the TREND trial may have had small vessel disease or other atherosclerotic disease, or strokes due to the narrowing of vessels or due to an unknown cause. They were also given 3 days of IV tirofiban, whereas the duration of antithrombotic treatment in MOST was shorter.
The TREND study was funded by the National Key Research and Development Program of China, the National Science Foundation of Beijing Municipality, and the Beijing Municipal Science and Technology Commission.

Even Moderate Exposure to Radon Tied to Increased Stroke Risk
Exposure to even moderate concentrations of radon is associated with a significant increase in stroke risk, new research suggests.
Radon is the second leading cause of lung cancer, but little was known about how exposure to the gas might affect stroke risk in women.
“Our research found an increased risk of stroke among participants exposed to radon above — and as many as 2 picocuries per liter (pCi/L) below — concentrations that usually trigger Environmental Protection Agency recommendations to install a home radon mitigation system,” senior author Eric A. Whitsel, MD, MPH, professor of epidemiology and medicine, University of North Carolina, Chapel Hill, said in a news release.
The study was published online on January 31, 2024, in Neurology.
Women Particularly Affected
Radon is a naturally occurring odorless radioactive gas produced when uranium or radium break down in rocks and soil. Its presence is increasing as a result of climate change, and it is increasingly being found in people’s homes. When inhaled, this air pollutant releases ionizing radiation in the lungs and is seen as second only to smoking as an established cause of lung cancer.
The National Radon Action Plan of the US Environmental Protection Agency (EPA) lays out testing and mitigation guidelines based on the known role of radon in lung carcinogenesis. But radon testing and mitigation are less common than recommended, and the EPA’s action plan doesn’t cover diseases other than lung cancer.
Compared with men, women have a higher rate of stroke and, in the US, typically spend about 11% more hours per day indoors at home, which investigators note highlights a “potential role of the residential environment among other risk factors specific to women.”
Researchers examined longitudinal associations between home radon exposure and incident stroke in 158,910 women at baseline (mean age 63.2 years; 83% White) over a mean follow-up of 13.4 years. During this time, participants experienced a total of 6979 strokes.
Participants’ home addresses were linked to radon concentration data drawn from the US Geological Survey and the EPA, which recommends that average indoor radon concentrations not exceed 4 pCi/L.
The highest radon exposure group resided in areas where average radon concentrations were < 4 pCi/L; the middle exposure group lived in regions with average concentrations of 2-4 pCi/L; and the lowest exposure group lived in areas with average concentrations < 2 pCi/L.
The researchers adjusted for demographic, social, behavioral, and clinical characteristics.
Public Health Implications
The incidence rates of stroke per 100,000 women in the lowest, middle, and highest radon concentration areas were 333, 343, and 349, respectively.
Stroke risk was 6% higher among those in the middle exposure group (adjusted hazard ratio [aHR], 1.06; 95% CI, 0.99-1.13) and 14% higher in the highest exposure group (aHR, 1.14; 95% CI, 1.05-1.22) compared with the lowest exposure group.
Notably, stroke risk was significant even at concentrations ranging from 2 to 4 pCi/L (P = .0004) vs < 2 pCi/L, which is below the EPA›s Radon Action Level for mitigation.
The findings remained robust in sensitivity analyses, although the associations were slightly stronger for ischemic stroke (especially cardioembolic, small-vessel occlusive, and very large artery atherosclerotic) compared with hemorrhagic stroke.
“Radon is an indoor air pollutant that can only be detected through testing that measures concentrations of the gas in homes,” Dr. Whitsel said in the release. “More studies are needed to confirm our findings. Confirmation would present an opportunity to improve public health by addressing an emerging risk factor for stroke.”
The study lacked gender and racial/ethnic diversity, so the findings may not be generalizable to other populations.
“Replication studies of individual-level radon exposures are needed to confirm this positive radon-stroke association,” the authors write. “Confirmation would present a potential opportunity to affect public health by addressing a pervasive environmental risk factor for stroke and thereby merit reconsideration of extant radon policy.”
The study was funded by the National Institute of Environmental Health Sciences and National Heart, Lung, and Blood Institute. Dr. Whitsel and coauthors report no relevant financial relationships.

FROM NEUROLOGY
Hypertension Before 35 Tied to Triple Stroke Risk in Midlife
The Black Women’s Health Study, which has followed 59,000 participants in the United States since the 1990s, also showed that those who develop hypertension before age 45 have twice the risk of suffering a stroke.
“The really concerning thing about this data is the high proportion of young Black women who had high blood pressure and are suffering strokes relatively early in life,” the study’s lead author, Hugo J. Aparicio, MD, associate professor of neurology at Boston University Chobanian & Avedisian School of Medicine, told this news organization. “This can lead to a burden of disability in relatively young women who may be at the prime of their life, pursuing careers and looking after family.”
Dr. Aparicio will present the data in full at the International Stroke Conference 2024 to be held in Phoenix, Arizona, Feb. 7-9.
He explained that while there has been good progress in reducing stroke rates in older people over the past decades, there is a concerning observation from multiple datasets showing that stroke rates in midlife have been plateauing or even increasing in recent years.
“For Black women specifically, there is a concern, as we know this group has higher rates of raised blood pressure and stroke overall,” said Dr. Aparicio. “We were interested in looking at whether the onset of hypertension at an earlier age in this group is one of the reasons for the increased stroke risk in midlife.”
The researchers analyzed data from the Black Women’s Health Study, a prospective study of 59,000 Black women from across the United States. The baseline year for this analysis, which included 46,754 stroke-free participants younger than age 65 (mean age, 42 years), was the 1999 questionnaire.
History of hypertension, defined as physician-diagnosed hypertension with the use of an antihypertensive medication, and of stroke occurrence was determined by self-report. It has been shown in previous studies that these self-reported data on incidence of hypertension in this dataset are highly reliable, Dr. Aparicio noted.
At baseline, 10.5% of participants aged 45-64 years had hypertension. Stroke occurred in 3.2% of individuals over a mean follow-up of 17 years.
Black women with hypertension before age 45 had a higher risk for midlife stroke (hazard ratio [HR], 2.23; 95% CI, 1.79-2.78), after adjustment for age, neighborhood socioeconomic status, residence in Stroke Belt, smoking, body mass index, and diabetes than women with no history of hypertension.
The risk was also increased with hypertension at midlife ages 45-64 years (HR, 1.69; 95% CI, 1.47-1.95) and was highest among those with hypertension at ages 24-34 years (HR, 3.15; 95% CI, 1.92-5.16).
“Our results show that among young Black women, those with hypertension have a much higher stroke risk than those without hypertension, even if they are taking antihypertensive medication,” Dr. Aparicio said. “This underscores how potent hypertension is as a risk factor for stroke.”
He concluded that both individuals and doctors need to realize that hypertension and stroke are not problems of the elderly exclusively.
“These are conditions that need to be addressed very early in life. This is even more important for Black women, as they are a high-risk group. They need to pay attention to blood pressure numbers early in life — ideally from adolescence — to catch levels before they become too elevated,” Dr. Aparicio said.
“We also need to address lifestyle changes including diet, physical activity, sleep habits, and address other cardiovascular risk factors such as cholesterol and body mass index, so we can prevent strokes from occurring,” he added. “At the policy level, we need to advocate, provide and fund primary prevention measures, and enable earlier screening and better treatment.”
The Role of Psychosocial Stressors
Commenting on the study, the American Heart Association immediate past president, Michelle A. Albert, MD, professor of medicine at the University of California, San Francisco, emphasized the importance of regular primary care appointments to screen for high blood pressure and other cardiovascular risk factors.
She pointed out that one of the contributing factors that may increase the risk for Black women is their disproportionate experience of psychosocial stressors and chronic cumulative stress.
This could include stress related to financial issues, racism and other forms of bias, the neighborhood environment, and having to take care of multiple generations of family with limited resources.
“These are some of the things that are less talked about as going into the heightened risk for many cardiovascular risk factors, including hypertension, very early in life for Black women that we need to bring to the forefront of conversations,” Dr. Albert said.
“These stressors not only impact hypertension onset but also they impact one’s ability to be able to seek help, and once the help is sought, to be able to sustain the therapies recommended and the interventions recommended,” she added.
The authors reported no relevant disclosures.

Aparicio, MD, associate professor of neurology at Boston University Chobanian & Avedisian School of Medicine, told this news organization. “This can lead to a burden of disability in relatively young women who may be at the prime of their life, pursuing careers and looking after family.”
Dr. Aparicio will present the data in full at the International Stroke Conference 2024 to be held in Phoenix, Arizona, Feb. 7-9.
He explained that while there has been good progress in reducing stroke rates in older people over the past decades, there is a concerning observation from multiple datasets showing that stroke rates in midlife have been plateauing or even increasing in recent years.
“For Black women specifically, there is a concern, as we know this group has higher rates of raised blood pressure and stroke overall,” said Dr. Aparicio. “We were interested in looking at whether the onset of hypertension at an earlier age in this group is one of the reasons for the increased stroke risk in midlife.”
The researchers analyzed data from the Black Women’s Health Study, a prospective study of 59,000 Black women from across the United States. The baseline year for this analysis, which included 46,754 stroke-free participants younger than age 65 (mean age, 42 years), was the 1999 questionnaire.
History of hypertension, defined as physician-diagnosed hypertension with the use of an antihypertensive medication, and of stroke occurrence was determined by self-report. It has been shown in previous studies that these self-reported data on incidence of hypertension in this dataset are highly reliable, Dr. Aparicio noted.
At baseline, 10.5% of participants aged 45-64 years had hypertension. Stroke occurred in 3.2% of individuals over a mean follow-up of 17 years.
Black women with hypertension before age 45 had a higher risk for midlife stroke (hazard ratio [HR], 2.23; 95% CI, 1.79-2.78), after adjustment for age, neighborhood socioeconomic status, residence in Stroke Belt, smoking, body mass index, and diabetes than women with no history of hypertension.
The risk was also increased with hypertension at midlife ages 45-64 years (HR, 1.69; 95% CI, 1.47-1.95) and was highest among those with hypertension at ages 24-34 years (HR, 3.15; 95% CI, 1.92-5.16).
“Our results show that among young Black women, those with hypertension have a much higher stroke risk than those without hypertension, even if they are taking antihypertensive medication,” Dr. Aparicio said. “This underscores how potent hypertension is as a risk factor for stroke.”
He concluded that both individuals and doctors need to realize that hypertension and stroke are not problems of the elderly exclusively.
“These are conditions that need to be addressed very early in life. This is even more important for Black women, as they are a high-risk group. They need to pay attention to blood pressure numbers early in life — ideally from adolescence — to catch levels before they become too elevated,” Dr. Aparicio said.
“We also need to address lifestyle changes including diet, physical activity, sleep habits, and address other cardiovascular risk factors such as cholesterol and body mass index, so we can prevent strokes from occurring,” he added. “At the policy level, we need to advocate, provide and fund primary prevention measures, and enable earlier screening and better treatment.”
The Role of Psychosocial Stressors
Commenting on the study, the American Heart Association immediate past president, Michelle A. Albert, MD, professor of medicine at the University of California, San Francisco, emphasized the importance of regular primary care appointments to screen for high blood pressure and other cardiovascular risk factors.
She pointed out that one of the contributing factors that may increase the risk for Black women is their disproportionate experience of psychosocial stressors and chronic cumulative stress.
This could include stress related to financial issues, racism and other forms of bias, the neighborhood environment, and having to take care of multiple generations of family with limited resources.
“These are some of the things that are less talked about as going into the heightened risk for many cardiovascular risk factors, including hypertension, very early in life for Black women that we need to bring to the forefront of conversations,” Dr. Albert said.
“These stressors not only impact hypertension onset but also they impact one’s ability to be able to seek help, and once the help is sought, to be able to sustain the therapies recommended and the interventions recommended,” she added.
The authors reported no relevant disclosures.

Colchicine May Benefit Patients With Diabetes and Recent MI
TOPLINE:
A daily low dose of colchicine significantly reduces ischemic cardiovascular events in patients with type 2 diabetes (T2D) and a recent myocardial infarction (MI).
METHODOLOGY:
- After an MI, patients with vs without T2D have a higher risk for another cardiovascular event.
- The Colchicine Cardiovascular Outcomes Trial (COLCOT), a randomized, double-blinded trial, found a lower risk for ischemic cardiovascular events with 0.5 mg colchicine taken daily vs placebo, initiated within 30 days of an MI.
- Researchers conducted a prespecified subgroup analysis of 959 adult patients with T2D (mean age, 62.4 years; 22.2% women) in COLCOT (462 patients in colchicine and 497 patients in placebo groups).
- The primary efficacy endpoint was a composite of cardiovascular death, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina requiring coronary revascularization within a median 23 months.
- The patients were taking a variety of appropriate medications, including aspirin and another antiplatelet agent and a statin (98%-99%) and metformin (75%-76%).
TAKEAWAY:
- The risk for the primary endpoint was reduced by 35% in patients with T2D who received colchicine than in those who received placebo (hazard ratio, 0.65; P = .03).
- The primary endpoint event rate per 100 patient-months was significantly lower in the colchicine group than in the placebo group (rate ratio, 0.53; P = .01).
- The frequencies of adverse events were similar in both the treatment and placebo groups (14.6% and 12.8%, respectively; P = .41), with gastrointestinal adverse events being the most common.
- In COLCOT, patients with T2D had a 1.86-fold higher risk for a primary endpoint cardiovascular event, but there was no significant difference in the primary endpoint between those with and without T2D on colchicine.
IN PRACTICE:
“Patients with both T2D and a recent MI derive a large benefit from inflammation-reducing therapy with colchicine,” the authors noted.
SOURCE:
This study, led by François Roubille, University Hospital of Montpellier, France, was published online on January 5, 2024, in Diabetes Care.
LIMITATIONS:
Patients were not stratified at inclusion for the presence of diabetes. Also, the study did not evaluate the role of glycated hemoglobin and low-density lipoprotein cholesterol, as well as the effects of different glucose-lowering medications or possible hypoglycemic episodes.
DISCLOSURES:
The COLCOT study was funded by the Government of Quebec, the Canadian Institutes of Health Research, and philanthropic foundations. Coauthors Jean-Claude Tardif and Wolfgang Koenig declared receiving research grants, honoraria, advisory board fees, and lecture fees from pharmaceutical companies, as well as having other ties with various sources.
