Physical activity, even as little as 15 minutes a day of moderate-intensity exercise, is linked with a lower risk of stroke and death in people with atrial fibrillation.

Men without evidence of low testosterone levels (hypogonadism) who use testosterone appear to face a higher risk of serious cardiovascular problems and death from all causes than men who use testosterone replacement therapy for documented hypogonadism, according to a 2026 study.

Symptoms of atrial fibrillation include a fluttering, pounding sensation in the chest and a lightheaded, dizzy, or breathless feeling. But about a quarter of people with this disorder don’t notice any symptoms.

Head or neck trauma can sometimes damage key arteries supplying the brain. Find out how this rare injury might trigger a stroke in younger adults.

Recent advances in caring for people with strokes include expanded access to medications and clot removal procedures. In certain cases, these therapies may be done up to 24 hours after stroke symptoms first appear.

All adults should get a lipoprotein(a) blood test at least once in their lifetime, according to the 2026 cholesterol guidelines. Also known as Lp(a), these fatty particles are similar to LDL (bad) cholesterol but more dangerous.

Aging and a family history can increase the risk for a stroke, but women can lower it by managing factors that are under their control-such as diet, exercise, blood pressure, smoking, and diabetes.

A cervical artery dissection is a tear in one of the arteries in the neck that carry blood to the brain. Although rare, it is one of the most common causes of stroke in people under age 50.

People who have gout, which results from excess uric acid in the body, are at increased risk for heart disease and stroke. A 2026 study found that maintaining uric acid levels below 6 mg/dL with medication reduced the risk for heart attack, stroke, and heart-related death.

The scientific understanding of HDL cholesterol has evolved in recent years, and many cardiologists now believe that HDL may be more of a bystander rather than a "good guy" that helps lower heart disease risk. While some types of HDL are great at plucking excess cholesterol from LDL and artery walls (a process referred to as reverse cholesterol transport) other types of HDL don't do this. In clinical trials, medications to raise HDL levels-including a drug specifically designed to improve reverse cholesterol transport-have not succeeded in lowering heart attacks and strokes.
