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.

In November 2022, the FDA called out seven supplement companies for illegally claiming their products could treat or prevent cardiovascular disease, such as atherosclerosis or heart failure.

Sometimes people miss the symptoms of life-threatening conditions such as a heart attack, a stroke, atrial fibrillation, or a pulmonary embolism. To detect the warning signs, people should pay attention to sudden, new symptoms, especially if they include shortness of breath, chest pain, heart palpitations, lightheadedness, confusion, weakness, fatigue, fainting, or a terrible headache. Someone experiencing any of these symptoms should call 911. If symptoms aren't sudden or intense, and people aren't sure if they warrant emergency help, they should call their doctor.
