Since its introduction in 1998, catheter ablation for atrial fibrillation has greatly improved, thanks to advances in the instruments, imaging techniques, and energy sources used during the procedure. The resulting increases in safety and effectiveness have transformed ablation into a routine procedure. For many people newly diagnosed with this heart rhythm disorder, ablation is now the first treatment offered.

Smart watches can monitor different parameters simply by measuring a person's pulse and body movements. Potentially helpful features include those to detect very low or high heart rates, irregular heart rhythms, and breathing disruptions during sleep.

Heart-friendly breakfast ideas include a mix of foods that provide protein, fiber, and unsaturated fat, which can help stave off hunger until lunchtime. Examples include eggs cooked with vegetables, Greek yogurt with berries and nuts, or oatmeal cooked with milk and topped with fruit. Other quick options are a slice of whole-grain toast spread with mashed avocado and cherry tomatoes, almond butter and sliced apple, or ricotta cheese and sliced kiwi.

For people with a family history of early heart disease, getting a coronary artery calcium (CAC) scan plus intensive coaching and a statin may help limit the progression of the plaque in their arteries, according to a 2025 study.

Trading about a tablespoon of butter per day for about two teaspoons of olive, soybean, or canola oil may help lower the risk of heart disease and premature death, according to a 2025 study.

When blood pressure remains high despite treatment, making certain lifestyle changes can help. Examples include reducing dietary sodium and increasing dietary potassium, losing weight, limiting alcohol intake to no more than one drink per day, exercising (doing aerobics and strength training), using tools that improve medication adherence (such as an automatic pill dispenser, a medication diary, a smartphone alarm, or a reminder app), quitting smoking, getting more sleep, managing stress, and reducing caffeine intake.

A 2025 study found that a new type of medication may safely slow the progression of aortic stenosis (narrowing of the aortic valve) and delay the need for valve replacement.

About one in every 20 people over age 65 has a stiff, narrowed aortic valve. A Harvard physician describes his experience with this condition, called aortic stenosis, from the heart murmur detected at age 66 to his open-heart surgery a decade later. After his diagnosis, he received echocardiograms every one to two years to check the valve, and later a stress echocardiogram. Because the echocardiogram revealed an aortic aneurysm, he had open-heart surgery so the surgeon could repair the valve and the aneurysm during the same operation.

A daily serving of cheese is linked to a lower risk of heart disease, stroke, and death from cardiovascular disease. But it's best to pair cheese with foods like whole-grain crackers or salad instead of combining it with refined carbohydrates and meat, such as cheese on burgers or pizza. Health-promoting fermentation products may counteract the saturated fat and sodium found in cheese.
