Three times as many people have atrial fibrillation than previously known

According to a 2024 study, the rapid, irregular heart rhythm known as atrial fibrillation is three times more prevalent than previously thought, and now affects an estimated 10.5 million Americans.

Drops in air pollution linked to fewer heart disease hospitalizations

A 2024 study found that when air pollution levels decreased during a five-year period in Italy, so did hospitalizations for heart-related emergencies. The results suggest that reducing air pollution could lower the prevalence of heart disease.

Device of the month: Smart ring

Smart rings can do many of the same things a smart watch can, including heart rate monitoring, blood oxygen level measurement, and activity and sleep tracking.

Broccoli beats potatoes for lowering blood pressure

Eating cruciferous vegetables like broccoli and cauliflower may reduce blood pressure more than eating squash and root veggies.

The latest thinking on inherited high cholesterol

About 5% of Americans have low-density lipoprotein (LDL) values of 190 mg/dL or higher. Their risk of heart disease is five times higher than people with near-optimal values (less than 130 mg/dL). Some have familial hypercholesterolemia, a genetic condition that can lead to LDL values up to 350 mg/dL (or even higher in some cases). Known as FH, it's a common cause of early heart attacks.

Tracking your afib with a smart watch? Avoid this pitfall

People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

Is snow shoveling safe for people with heart disease?

Snow shoveling can be risky for people with heart disease because (1) the activity requires a lot of physical effort, and (2) cold temperatures constrict arteries. Both factors can raise the risk of a heart attack in people with narrowed heart arteries.

Need a push to learn CPR?

People can learn how to give chest compressions-a key aspect of cardiopulmonary resuscitation, or CPR-by watching a 90-second online video. CPR keeps blood flowing to the brain and vital organs during a cardiac arrest. There are various ways to practice chest compressions on a mannequin, including at an in-person class or at one of 30 kiosks (including six at major airports) located nationwide.

Medication side effects: What are your options?

All medicines have potential side effects. Usually, side effects are more bothersome than serious -- though a few are dangerous. If you experience a side effect, what are your options?

Fixing a leaky tricuspid valve

In 2024, the FDA approved two catheter-based devices for treating a leaky tricuspid valve. Both relieve symptoms and improve quality of life for people with moderate to severe tricuspid regurgitation, which affects about 4% of people ages 75 and older. One device is a modification of a system to treat mitral valve regurgitation that works by bringing the valve leaflets together at the areas of most severe leakage. The other device delivers a new valve made of cow heart tissue, which is commonly used in surgical valve replacements.
