Stroke

Adults with persistent metabolic syndrome that worsens over time are at increased risk for any type of cancer, according to a new study of more than 44,000 individuals.

The conditions that comprise metabolic syndrome (high blood pressure, high blood sugar, increased abdominal adiposity, and high cholesterol and triglycerides) have been associated with an increased risk of diseases, including heart disease, stroke, and type 2 diabetes, wrote Li Deng, PhD, of Capital Medical University, Beijing, China, and colleagues.

A systematic review and meta-analysis published in Diabetes Care in 2012 showed an association between the presence of metabolic syndrome and an increased risk of various cancers including liver, bladder, pancreatic, breast, and colorectal.

More recently, a 2019 study published in Diabetes showed evidence of increased risk for certain cancers (pancreatic, kidney, uterine, cervical) but no increased risk for cancer overall.

However, the reasons for this association between metabolic syndrome and cancer remain unclear, and the effect of the fluctuating nature of metabolic syndrome over time on long-term cancer risk has not been explored, the researchers wrote.
 

What Does New Study Add to Other Research on Metabolic Syndrome and Cancer Risk?

In the new study, published in Cancer on March 11 (doi: 10.1002/cncr.35235), 44,115 adults in China were separated into four trajectories based on metabolic syndrome scores for the period from 2006 to 2010. The scores were based on clinical evidence of metabolic syndrome, defined using the International Diabetes Federation criteria of central obesity and the presence of at least two other factors including increased triglycerides, decreased HDL cholesterol, high blood pressure (or treatment for previously diagnosed hypertension), and increased fasting plasma glucose (or previous diagnosis of type 2 diabetes).

The average age of the participants was 49 years. The four trajectories of metabolic syndrome were low-stable (10.56% of participants), moderate-low (40.84%), moderate-high (41.46%), and elevated-increasing (7.14%), based on trends from the individuals’ initial physical exams on entering the study.

Over a median follow-up period of 9.4 years (from 2010 to 2021), 2,271 cancer diagnoses were reported in the study population. Those with an elevated-increasing metabolic syndrome trajectory had 1.3 times the risk of any cancer compared with those in the low-stable group. Risk for breast cancer, endometrial cancer, kidney cancer, colorectal cancer, and liver cancer in the highest trajectory group were 2.1, 3.3, 4.5, 2.5, and 1.6 times higher, respectively, compared to the lowest group. The increased risk in the elevated-trajectory group for all cancer types persisted when the low-stable, moderate-low, and moderate-high trajectory pattern groups were combined.

The researchers also examined the impact of chronic inflammation and found that individuals with persistently high metabolic syndrome scores and concurrent chronic inflammation had the highest risks of breast, endometrial, colon, and liver cancer. However, individuals with persistently high metabolic syndrome scores and no concurrent chronic inflammation had the highest risk of kidney cancer.
 

 What Are the Limitations of This Research?

The researchers of the current study acknowledged the lack of information on other causes of cancer, including dietary habits, hepatitis C infection, and Helicobacter pylori infection. Other limitations include the focus only on individuals from a single community of mainly middle-aged men in China that may not generalize to other populations.

Also, the metabolic syndrome trajectories did not change much over time, which may be related to the short 4-year study period.
 

What Is the Takeaway Message for Clinical Practice?

The results suggest that monitoring and managing metabolic syndrome could help reduce cancer risk, the researchers concluded. 

“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” senior author Han-Ping Shi, MD, PhD, of Capital Medical University in Beijing, said in a press release accompanying the study.

More research is needed to assess the impact of these interventions on cancer risk, he noted. However, the data from the current study can guide future research that may lead to more targeted treatments and more effective preventive strategies, he said in a statement.

The study was supported by the National Key Research and Development Program of China. The researchers had no financial conflicts to disclose.

A new and deceptively simple advance in chronic stroke treatment could be a vibrating glove.

Researchers at Stanford University and Georgia Tech have developed a wearable device that straps around the wrist and hand, delivering subtle vibrations (akin to a vibrating cellphone) that may relieve spasticity as well as or better than the standard Botox injections.

“The vibro-tactile stimulation can be used at home, and we’re hoping it can be relatively low cost,” said senior study author Allison Okamura, PhD, a mechanical engineer at Stanford University, Stanford, California.

For now, the device is available only to clinical trial patients. But the researchers hope to get the glove into — or rather onto — more patients’ hands within a few years. A recent grant from the National Science Foundation’s Convergence Accelerator program could help pave the way to a commercial product. The team also hopes to expand access in the meantime through larger clinical trials with patients in additional locations.

The work builds on accumulating research exploring vibration and other stimulation therapies as treatments for neurological conditions. Other vibrating gloves have helped reduce involuntary movement for patients with Parkinson’s. And the University of Kansas Medical Center, Kansas City, will soon trial the Food and Drug Administration–approved vagal nerve stimulator, an implantable device intended to treat motor function in stroke survivors. Dr. Okamura noted that devices use “different types of vibration patterns and intensities,” depending on the disease state they target.

Spasticity often develops or worsens months after a stroke. By then, patients may have run out of insurance coverage for rehabilitation. And the effectiveness of Botox injections can “wear out over time,” Dr. Okamura said.

In a clinical trial, patients wore the device for 3 hours a day for 8 weeks, while doing their usual activities. The researchers continued testing their spasticity for 2 more weeks. Symptom relief continued or improved for some patients, even after they stopped using the device. More than half of the participants experienced equal or better results than another group that received only regular Botox injections.
 

How Vibro-Tactile Stimulation May Rewire the Brain

The device originated at Georgia Tech, where Dr. Okamura’s postdoctoral research fellow Caitlyn Seim, PhD, was using vibro-tactile stimulation (VTS) to teach people skills, such as playing the piano, using touch-feedback training. The team decided to target spasticity, which VTS had helped in previousstudies of in-clinic (non-wearable) devices.

How does the device work? The researchers point to neuroplasticity, the ability of neurons to create new synapses or strengthen existing ones in the brain.

“The stimulation is sending additional sensory signals to the brain, which helps the brain interpret and reconnect any lost circuits,” Dr. Okamura said.

Spasticity is driven by “an imbalance in the excitatory drive to the muscles,” she continued. This can lead to worsening contractions, until a hand closes into a fist or a foot curls up. (The team has also done preliminary research on a similar device for foot spasticity, which they hope to continue developing.) Previous studies by Okamura and others suggest that vibration stimulation may prevent these contractions, both in the short and long term.

“Immediately, we do see some softening of the muscles,” Dr. Okamura said. “But in our longer-term study, where we compared to Botox, I also think that the vibration may be retraining the brain to send inhibitory signals. And that can restore balance that’s lost due to the damaged neural circuits from a stroke.”

When the team did a separate study comparing the effects of muscle and skin stimulation, they hypothesized that the vibration could be having a biomechanical effect on the muscle. Instead, they found that stimulating the skin had a greater impact — a “somewhat unexpected” result, Dr. Okamura said. That led them to the brain.

“Stimulating the skin is really about creating sensory signals that get sent to the brain,” Dr. Okamura said, “which is why we think it’s actually a brain-retraining effect and not a direct biomechanical effect.”
 

What’s Next?

The researchers are seeking funding for longer-term clinical studies to find out if effects persist beyond 2 weeks. They also want to explore how long and often patients should wear the glove for best results.

The researchers also want to study how movement might enhance the effects of the device.

“One of the treatments for spasticity — medications aside, this vibration machine aside — is more exercise, more passive range of motion,” said Oluwole O. Awosika, MD, associate professor at the University of Cincinnati College of Medicine, who was not involved in the study. “It would have been nice to have a control group that didn’t get any of this stimulation or that was only encouraged to do 3 hours of movement a day. What would the difference be?”

Dr. Awosika also wondered how easy it would be for stroke patients without in-home assistance to use the device. “Sometimes wearing these devices requires someone to put it on,” he said.

Of course, if all goes well, patients wouldn’t have to deal with that forever. “The dream would be that you reach true rehabilitation, which is no longer needing the device,” Dr. Okamura said.

Dear colleagues, I’m Christoph Diener from the medical faculty of University Duisburg-Essen in Germany. Today I would like to tell you about five interesting studies that were published in January 2024.
 

Long COVID

I would like to start with long COVID. There is an ongoing discussion about whether this condition — which means symptoms like dizziness, vertigo, fatigue, headache, and cognitive impairment that persist for more than 6 months — is either a consequence of the infection, functional symptoms, psychosomatic disease, or a depression.

There is an important paper that came out in Science. The group investigated 39 controls and 113 patients who had COVID-19. At 6 months, 40 of them had long COVID. The researchers repeatedly measured more than 6500 proteins in serum. The patients with long COVID had a significant increase in complement activation, which persisted even beyond 6 months. These patients also showed increased tissue lesion markers in the blood and activation of the endothelium.

Also, they had increased platelet activation and autoantibodies with increased anti-cytomegalovirus and anti-Epstein-Barr virus immunoglobulins. These are very strong indicators that COVID-19 leads to long-term changes in our immune system, and different activations of complement factors could explain the variety of symptoms that these patients display. Whether this has consequences for treatment is unclear at the moment.
 

Parkinson’s Classification

Let me come to another issue, which is the future treatment of Parkinson’s disease, covered in a paper in The Lancet Neurology. I think you are all aware that once patients display symptoms like rigidity, bradykinesia, or tremor, it’s most probably too late for neuroprotective therapy because 70% of the dopaminergic neurons are already dead.

The authors propose a new biological diagnosis of the disease in the preclinical state. This early preclinical diagnosis has three components. One is to show the presence of synuclein either in skin biopsy or in serum. The second is proof of neurodegeneration either by MRI or by PET imaging. The third involves genetic markers.

On top of this, we know that we have preclinical manifestations of Parkinson’s disease, like REM sleep disorders, autonomic disturbances, and cognitive impairment. With this new classification, we should be able to identify the preclinical phase of Parkinson’s disease and include these patients in future trials for neuroprotection.
 

Niemann-Pick Disease

My third study, in The New England Journal of Medicine, deals with Niemann-Pick disease type C (Trial of N-Acetyl-l-Leucine in Niemann–Pick Disease Type C. This is a rare autosomal recessive disorder that involves impaired lysosomal storage. This disease, which manifests usually in childhood, goes along with systemic, psychiatric, and neurologic abnormalities, and in particular, ataxia. Until now, there has been only one therapy, with miglustat. which has many side effects.

The group of authors found a new therapeutic approach with N-acetyl-L-leucine, which primarily increases mitochondrial energy production. This was a small, placebo-controlled, crossover trial with 2 x 12 weeks of treatment. This new compound showed efficacy and was very well tolerated. This shows that we definitely need long-term studies with this new, well-tolerated drug in this rare disease.
 

Anticoagulation in Subclinical AF

My fourth study comes from the stroke-prevention field, published in The New England Journal of Medicine. I think you are aware of subclinical atrail fibrillation. These are high-frequency episodes in ECG, usually identified by pacemakers or ECG monitoring systems. The international ARTESIA study included more than 4000 patients randomized either to apixaban 5 mg twice daily or aspirin 81 mg.

After 3.5 years, the investigators showed a small but significant decrease in the rate of stroke, with a relative risk reduction of 37%, but also, unfortunately, a significantly increased risk for major bleeding with apixaban. This means that we need a careful discussion with the patient, the family, and the GP to decide whether these patients should be anticoagulated or not.
 

Migraine and Depression

My final study, published in the European Journal of Neurology, deals with the comorbidity of depression and migraine. This study in the Netherlands included 108 patients treated with erenumab and 90 with fremanezumab; 68 were controls.

They used two depression scales. They showed that treatment with the monoclonal antibodies improved at least one of the two depression scales. I think this is an important study because it indicates that you can improve comorbid depression in people with severe migraine, even if this study did not show a correlation between the reduction in monthly migraine days and the improvement of depression.

What we learned for clinical practice is that we have to identify depression in people with migraine and we have to deal with it. Whether it’s with the treatment of monoclonal antibodies or antidepressant therapy doesn’t really matter.

Dear colleagues, we had interesting studies this month. I think the most spectacular one was published in Science on long COVID. Thank you very much for listening and watching. I’m Christoph Diener from University Duisburg-Essen.

These patients also showed increased tissue lesion markers in the blood and activation of the endothelium.

Also, they had increased platelet activation and autoantibodies with increased anti-cytomegalovirus and anti-Epstein-Barr virus immunoglobulins. These are very strong indicators that COVID-19 leads to long-term changes in our immune system, and different activations of complement factors could explain the variety of symptoms that these patients display. Whether this has consequences for treatment is unclear at the moment.
 

Parkinson’s Classification

Let me come to another issue, which is the future treatment of Parkinson’s disease, covered in a paper in The Lancet Neurology. I think you are all aware that once patients display symptoms like rigidity, bradykinesia, or tremor, it’s most probably too late for neuroprotective therapy because 70% of the dopaminergic neurons are already dead.

The authors propose a new biological diagnosis of the disease in the preclinical state. This early preclinical diagnosis has three components. One is to show the presence of synuclein either in skin biopsy or in serum. The second is proof of neurodegeneration either by MRI or by PET imaging. The third involves genetic markers.

On top of this, we know that we have preclinical manifestations of Parkinson’s disease, like REM sleep disorders, autonomic disturbances, and cognitive impairment. With this new classification, we should be able to identify the preclinical phase of Parkinson’s disease and include these patients in future trials for neuroprotection.
 

Niemann-Pick Disease

My third study, in The New England Journal of Medicine, deals with Niemann-Pick disease type C (Trial of N-Acetyl-l-Leucine in Niemann–Pick Disease Type C. This is a rare autosomal recessive disorder that involves impaired lysosomal storage. This disease, which manifests usually in childhood, goes along with systemic, psychiatric, and neurologic abnormalities, and in particular, ataxia. Until now, there has been only one therapy, with miglustat. which has many side effects.

The group of authors found a new therapeutic approach with N-acetyl-L-leucine, which primarily increases mitochondrial energy production. This was a small, placebo-controlled, crossover trial with 2 x 12 weeks of treatment. This new compound showed efficacy and was very well tolerated. This shows that we definitely need long-term studies with this new, well-tolerated drug in this rare disease.
 

Anticoagulation in Subclinical AF

My fourth study comes from the stroke-prevention field, published in The New England Journal of Medicine. I think you are aware of subclinical atrail fibrillation. These are high-frequency episodes in ECG, usually identified by pacemakers or ECG monitoring systems. The international ARTESIA study included more than 4000 patients randomized either to apixaban 5 mg twice daily or aspirin 81 mg.

After 3.5 years, the investigators showed a small but significant decrease in the rate of stroke, with a relative risk reduction of 37%, but also, unfortunately, a significantly increased risk for major bleeding with apixaban. This means that we need a careful discussion with the patient, the family, and the GP to decide whether these patients should be anticoagulated or not.
 

Migraine and Depression

My final study, published in the European Journal of Neurology, deals with the comorbidity of depression and migraine. This study in the Netherlands included 108 patients treated with erenumab and 90 with fremanezumab; 68 were controls.

They used two depression scales. They showed that treatment with the monoclonal antibodies improved at least one of the two depression scales. I think this is an important study because it indicates that you can improve comorbid depression in people with severe migraine, even if this study did not show a correlation between the reduction in monthly migraine days and the improvement of depression.

What we learned for clinical practice is that we have to identify depression in people with migraine and we have to deal with it. Whether it’s with the treatment of monoclonal antibodies or antidepressant therapy doesn’t really matter.

Dear colleagues, we had interesting studies this month. I think the most spectacular one was published in Science on long COVID. Thank you very much for listening and watching. I’m Christoph Diener from University Duisburg-Essen.

Dear colleagues, I’m Christoph Diener from the medical faculty of University Duisburg-Essen in Germany. Today I would like to tell you about five interesting studies that were published in January 2024.
 

Long COVID

I would like to start with long COVID. There is an ongoing discussion about whether this condition — which means symptoms like dizziness, vertigo, fatigue, headache, and cognitive impairment that persist for more than 6 months — is either a consequence of the infection, functional symptoms, psychosomatic disease, or a depression.

There is an important paper that came out in Science. The group investigated 39 controls and 113 patients who had COVID-19. At 6 months, 40 of them had long COVID. The researchers repeatedly measured more than 6500 proteins in serum. The patients with long COVID had a significant increase in complement activation, which persisted even beyond 6 months. These patients also showed increased tissue lesion markers in the blood and activation of the endothelium.

Also, they had increased platelet activation and autoantibodies with increased anti-cytomegalovirus and anti-Epstein-Barr virus immunoglobulins. These are very strong indicators that COVID-19 leads to long-term changes in our immune system, and different activations of complement factors could explain the variety of symptoms that these patients display. Whether this has consequences for treatment is unclear at the moment.

A prognostic tool may facilitate the early identification of older adults in the community who would benefit from palliative care in their final years, new research from Canada suggested.

The analysis of data from close to a quarter million community-dwelling older adults in Ontario with at least one interRAI (Resident Assessment Instrument) home care assessment showed that only half of those with an estimated survival of fewer than 3 months received at least one palliative home care visit before death.

“One of the challenges and a barrier to accessing palliative home care is the difficulty of predicting survival,” Amy Hsu, PhD, an investigator at the Bruyère Research Institute in Ottawa, Ontario, Canada, told this news organization. “Clinicians are good at prognosticating when a patient might be entering their last 3-6 weeks of life, but they have a harder time predicting if someone will survive 6 months or longer.”

The team developed the Risk Evaluation for Support: Predictions for Elder-life in their Communities Tool (RESPECT) to see whether access to predicted survival data could inform conversations about a patient’s status and palliative care needs.

The study was published online in the Canadian Medical Association Journal.
 

Setting Care Goals

Researchers analyzed population health administrative data from Ontario involving home care clients who received at least one interRAI Home Care assessment between April 2018 and September 2019. The cohort included 247,377 adults (62% women) with a mean age of 80.1 years at the time of assessment. Comorbidities, including congestive heart failure, coronary artery disease, cancer, and chronic obstructive pulmonary disease, as well as symptoms of health instability, were more prevalent among those at higher risk of dying.

The team used an updated, validated version of RESPECT to predict survival.

Only 2.6% of home care clients had received a clinician diagnosis of an end-stage disease, which was more prevalent among those at highest mortality risk (77.9%). Most clients (74.5%) required extensive assistance in performing instrumental activities of daily living (ADLs, score ≤ 4), and half (50.3%) were less able to perform ADLs in the last 3 months of life.

Within the cohort, 75% of patients with a predicted median survival of fewer than 3 months, 55.4% of those with a predicted median survival between 3 and 6 months, and 40.7% of those with a predicted median survival between 6 and 12 months died within 6 months of the home care assessment.

Among decedents, 50.6% of those with a RESPECT-estimated median survival of fewer than 3 months received at least one nonphysician palliative home care visit before death. Less than a third (27.8%) received at least one palliative home care visit from a physician.

The proportion of those who received at least one nonphysician visit fell to 38.7% among those with a median survival of between 3 and 6 months and to 29.5% among those with a median survival of between 6 and 12 months.

Patients who received at least one palliative home care visit (from either physicians or nonphysician home care providers) within 6 months of an assessment had clinical characteristics similar to those who did not receive a visit. However, those who did not receive palliative home care were more likely to not have been identified by a clinician as being in their past 6 months of life.

“These results reinforce the role of clinicians in identifying older adults who may be in their last 6 months of life as an important component for the receipt of palliative home care and highlight the value of RESPECT in supplementing clinicians’ assessments of prognosis,” the authors wrote.

“Our goal is to use data and tools like RESPECT to help individuals living with a life-limiting illness have conversations about what their end-of-life care goals and wishes may be and discuss whether a referral to palliative care is appropriate or needed,” Dr. Hsu added. “Data about life expectancy could be helpful for framing these conversations.”

The researchers are working with partners in home, community care, and long-term care to implement RESPECT in their settings.
 

‘Valuable Tool’

Guohua Li, MD, DrPH, professor of epidemiology and anesthesiology at Columbia University Mailman School of Public Health and Vagelos College of Physicians and Surgeons in New York City, commented on the findings for this news organization. He noted that the study is “rigorously designed and meticulously analyzed. The findings are of high validity and population health significance.”

The findings are comparable with what is seen in the United States and Canada, he said, where about 50% of terminally ill patients die at home or in hospice. However, palliative care outside of North America “varies greatly, and in many developing countries, [it] is still in its infancy.”

As a mortality risk prediction algorithm, “RESPECT seems to perform reasonably well,” he said. “If incorporated into the electronic health record, it could be a valuable tool for clinicians to identify patients with less than 6 months of life expectancy and deliver palliative care to these patients. RESPECT appears to be particularly beneficial for home care patients without a clinically diagnosed terminal disease.”

That said, he added, “RESPECT should be viewed as a clinical decision support tool. It is no substitute for clinicians or clinical judgment. Based on the data presented in the paper, the algorithm tends to overestimate the short-term mortality risk for home care patients, therefore resulting in many false alarms.”

The study was supported by the Canadian Institutes of Health Research and the Associated Medical Services. Dr. Hsu is an executive lead on the steering committee of the Ontario Centres for Learning, Research, and Innovation in Long-Term Care. Funding for the centers comes from the Ontario Ministry of Health and Ministry of Long-Term Care and is partially administered by the Bruyère Research Institute. Dr. Li reported no relevant financial interests.

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.

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.

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.

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.

PHOENIX — Adding either argatroban or eptifibatide to thrombolytic therapy doesn’t improve function following an ischemic stroke, 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.” 

Dr. Adeoye and Dr. Barreto report research funding from the National Institutes of Health/National Institute of Neurological Disorders and Stroke. Dr. Adeoye also reports an executive role, receiving royalties/being a patent beneficiary, Sense Diagnostics, Inc. Dr. Goldstein has no relevant conflicts of interest.

“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 — Adding either argatroban or eptifibatide to thrombolytic therapy doesn’t improve function following an ischemic stroke, 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.

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.

PHOENIX — Black women who develop high blood pressure before age 35 have a threefold increased risk of having a midlife stroke, 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.

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.”
