Physical activity, the brain, and a possible link to better heart health

Physical activity lowers cardiovascular disease risk in part by reducing stress-related activity in the brain, according to a 2024 study.

Spouse's heart disease linked to higher risk of depression

The spouses of people who have heart attacks, strokes, and heart failure may face an elevated risk of depression, according to a 2024 study.

Web-based app helps people accurately assess need for statin

Using a Web-based app, most people can correctly assess their need for a cholesterol-lowering statin and take the drug appropriately with good results, according to a 2024 study. If approved, the app could facilitate statin use without a doctor's prescription.

Sitting less may help lower blood pressure

Older adults might be able to lower their blood pressure by reducing their sitting time by as little as 30 minutes per day, according to a 2024 study.

Artificial intelligence in cardiology

The American Heart Association's first-ever scientific statement on artificial intelligence (A.I.) in cardiology explores how the technology may improve how doctors prevent, detect, and treat heart disease. For example, A.I. data from patch monitors may predict who will develop potentially serious heart rhythms. Applying A.I. tools to a single chest x-ray may predict a person's risk of heart attack and other serious health problems.

Protect your heart during the dog days of summer

People who have or are at risk for cardiovascular disease should be extra cautious when exercising outside when it's hot, humid, and hazy, as they are more vulnerable to the hazards of high temperature and air pollution. To exercise safely during a heat wave, people should avoid being outside during the middle of the day; wear light-colored, lightweight clothing; and be careful to stay hydrated.

Cardiovascular risks soar among daily cannabis users

A 2024 study suggests using cannabis weekly may be associated with an increase in people's risks of heart attack and stroke, and the risks rise dramatically with more frequent use.

Heart failure might be the most common complication of atrial fibrillation

A large observational study published in 2024 suggests that stroke isn't the biggest risk of atrial fibrillation (an abnormal heart rhythm condition). The biggest risk seems to be heart failure, a condition in which the heart is unable to pump blood effectively.

Can intermittent fasting improve heart health?

Intermittent fasting may help people lose weight and improve their cholesterol levels and other heart-related risks. One form of intermittent fasting is time-restricted eating, during which people eat only during a certain time window (usually eight hours) each day. Another approach, alternate-day fasting, involves fasting or significantly limiting calories for one or two days per week. But it's hard to maintain over the long run due to the challenges of following a strict eating schedule while juggling various work, family, and social commitments.

Why do some heart drugs cost so much?

Health insurance companies sometimes require prior authorization for new, expensive medications. The high price patients pay for these drugs is related to complexities in health insurance coverage.
