A narrowed aortic valve (aortic stenosis) affects about one in 20 people over age 65. Medical therapies for treating this progressive disease are under investigation, and a recent study explored the potential benefits of proactive valve replacement.

After a successful catheter ablation to treat atrial fibrillation, some people may safely stop taking anti-clotting medications. But the decision to discontinue those drugs depends on a person's underlying risk of stroke rather than the success of the procedure.

Electrical cardioversion is generally a safe, painless procedure used to convert a rapid or irregular heartbeat (such as atrial fibrillation) back to a normal rhythm. It’s done under sedation and takes only a few minutes.

A 2025 review of past research found that electromagnetic field exposure from electric cars poses no immediate health risks for people with implanted heart devices, such as pacemakers or implantable cardioverter-defibrillators.

People with prediabetes who successfully lower their blood sugar back to normal levels may cut their future risk of death due to heart disease by half, according to a 2025 study.

A 2025 study finds that among people with high blood pressure, waking up from sleep to urinate is closely linked to elevated blood pressure during sleep.

Compression socks are snug, supportive stockings that can help people who struggle with leg swelling or circulation issues. They're commonly used for certain vein problems or clot risks, and a doctor can help decide who needs them and how to use them.

Vasovagal syncope, a common cause of fainting, occurs when the vagus nerve becomes overstimulated in response to triggers such as stress or dehydration. Certain strategies, such as lying down and elevating the legs, help people avoid passing out.

Avocados have a mix of fiber, healthy fat, antioxidants, and key minerals that support heart health. But avocados aren't low-calorie foods. They're best added to the diet by swapping them for something else, such as subbing mashed avocado for butter on toast.

Many people with atrial fibrillation - a rapid, irregular heart rhythm - need medications to control symptoms and lower their risk of stroke. These include drugs that slow down the heart, help restore its rhythm, and prevent blood clots.
