County analysis reveals deep geographic and racial heart disease disparities

Despite sustained declines in overall cardiovascular disease mortality in the U.S., disparities based on race, ethnicity and place still persist, with mortality varying far more across counties than states, according to a county-by-cause-by-population analysis published in JACC, the flagship journal of the American College of Cardiology (ACC).

Human dental pulp stem cell secretome boosts stroke recovery

Ischemic stroke can leave lasting neurological damage after the initial vascular event, with oxidative stress, neuroinflammation, neuronal death, and disruption of neural connectivity contributing to impaired recovery.

Could the gut be priming the body for a more severe stroke?

Gut bacteria may prime immune cells to worsen stroke damage

Stroke reshapes brain environment to accelerate glioma progression

After a stroke, the brain gets to work repairing damaged tissue. But new research suggests some of the same biological processes that aid recovery may also help tumor cells grow and spread.

Gut bacterial metabolite worsens brain damage after stroke, study finds

Researchers at LMU have discovered how a metabolite produced by gut bacteria can influence brain damage after stroke.

Stroke rates nearly doubled among younger adults over three decades

Stroke is becoming more common among younger adults, according to a study published September 23, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Is stroke risk higher after a cancer diagnosis?

New research indicates that people with invasive cancer face an elevated risk of experiencing a stroke, especially in the first few months after diagnosis and especially if they have certain types of cancer.

Immigrants face longer ICU stays after stroke in Canada

Among people who have a stroke in Canada, immigrants were admitted to the intensive care unit (ICU) at similar rates as long-term residents or people who were born in Canada, but they were more likely to have longer stays in the ICU, according to a study published September 2, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Study reveals why many patients fail to recover after stroke

A clot forms. Blood flow to the brain is blocked. Starved of oxygen, neurons begin to die.

The US switch in shingles vaccines revealed an unexpected heart health pattern

In a natural experiment involving 72,920 propensity-matched US adults aged 60 years and older, recombinant shingles vaccination was associated with a 9% lower cardiovascular disease burden over seven years compared with the live attenuated vaccine. Lower burdens of ischemic heart disease and heart failure were seen in both sexes, while ischemic stroke was significantly lower only among men, supporting further clinical trials and mechanistic studies

New stroke guideline mandates personalized and early rehabilitation

A stroke can change life in an instant, affecting everything from walking and speaking to memory, mood and the ability to perform everyday tasks.

Overuse of short-acting bronchodilator linked to increased risk of cardiovascular diseases and death

Overuse of reliever inhalers is associated with higher risks of developing and dying from cardiovascular disease, including heart failure, heart attack and ischemic stroke, in asthma and COPD patients, according to a study published today in ERJ Open Research.

Global study reveals rising chronic kidney disease burden in women

Chronic kidney disease is now the seventh leading cause of death among noncommunicable diseases globally, affecting 11–13% of the adult population.

What 3,600 adults with diabetes revealed about lifestyle and heart health

In 3,612 British adults with type 2 diabetes, greater adherence to the Mediterranean Lifestyle Index was associated with lower risks of major adverse cardiovascular events, cardiovascular death, and all-cause mortality over more than a decade of follow-up. Dietary patterns, physical activity, rest, and social habits all contributed to the observed associations, although the observational study cannot establish causality.

Severe mental illness may accelerate dementia and stroke vulnerability

People living with severe mental illness face a substantially higher risk of dementia throughout adulthood, as well as a significantly elevated risk of stroke in early and middle adulthood, according to a large new study based on health records from Catalonia, Spain.

Automated MRI system improves improves evaluation of experimental stroke therapies

Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed an automated system that uses MRI to measure brain tissue changes in animal models for large, multicenter studies of experimental stroke treatments.

Tirzepatide lowers heart attack and cardiovascular event risk in adults with type 2 diabetes

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.

Researchers develop artery-on-a-chip platform to predict stroke risk

Predicting an individual's risk of ischemic stroke is difficult because thrombosis embolization-the process of a blood clot detaching from the area where it formed and traveling to and then sticking in another blood vessel-is based on factors that are unique to each person.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Racial and geographic disparities continue affecting stroke treatment outcomes

Three studies presented today at the Society of NeuroInterventional Surgery's (SNIS) 23rd Annual Meeting found that racial, geographic and socioeconomic disparities continue to influence stroke treatment and outcomes across the United States.
