Heart palpitations are defined as an awareness of a strong, rapid, or irregular heartbeat. They are among the most common reasons people consult general internists and cardiologists. Most brief rhythm disruptions are harmless, such as those caused by an earlier-than-usual contraction of the heart's upper chambers (atria) or lower chambers (ventricles). These are often perceived as either a skipped beat or a pounding or flip-flopping sensation. A fluttering sensation in the chest may suggest an unusually fast heart rate, which can result from an electrical misfire in the upper part of the heart and may require treatment.

Drugs that discourage blood clots (commonly called blood thinners) don't actually make the blood less viscous. The two main types of these drugs, anticoagulants and antiplatelet drugs, interfere with different blood components involved in clot formation. Anticoagulants treat blood clots in the legs and lungs and are also prescribed to people with atrial fibrillation. Antiplatelet drugs are used to prevent heart attacks and strokes and to treat people who receive stents.

When doctors insert a stent into the heart's artery, they usually enter the body through an artery at the top of the thigh. But for some people, using a vessel in the arm may be a safer and less costly option.

Triglycerides are the most common form of fat both in food and in the bloodstream. Growing evidence suggests that above-normal triglyceride levels can raise the risk of cardiovascular disease.

Most people typically get around 3,000 to 4,000 steps per day doing things such as household chores, going to the mailbox, or grocery shopping. But people who walk 8,000 steps per day (about 4 miles in total) may live longer than those who walk just 4,000 steps per day—and walking speed doesn't seem to matter. People who walk 12,000 steps per day may live even longer than those who take 8,000 steps. But the added benefit was small, and walking even more may not make a difference.

A 2023 study suggests that the type of technology used in smart watches to measure the heart's electrical activity may have the potential to detect early signs of heart failure or atrial fibrillation.

The Watchman, a tiny, basket-like device placed in the heart's left atrial appendage, is designed to prevent blood clots traveling from the heart to the brain and causing stroke. People with atrial fibrillation who face a high risk of bleeding from anti-clotting drugs may be good candidates for the device.

Obstructive sleep apnea is a condition marked by brief pauses in breathing, often triggering loud snoring, grunts, gasps, and choking noises. Because sleep apnea can put stress on your heart and circulation, it's important to learn the signs and symptoms and get treatment.

A 2023 study found that the DASH diet, rich in whole grains, lean protein, nuts, low-fat dairy, and fruits and vegetables, may dramatically lower the risk of heart problems in women and Black adults.

People who have had shingles have a 30% increased risk for heart disease and stroke, says a new Harvard study. Learn more about the risk.
