A thoracic aortic aneurysm can be small and stable, or it can tear or rupture. People with certain genetic conditions, and those who have a relative who has had this condition, are at higher risk and should be tested.

The likelihood of someone needing a pacemaker increases with age. This tiny battery-powered device, implanted into the chest, improves abnormal heart rhythms and improves blood flow if the heart does not pump effectively. By helping the heart maintain more normal function, pacemakers enable many individuals with certain heart conditions to resume their normal lifestyle and stay active longer.

People with certain heart conditions, including a replaced or repaired heart valve, should take antibiotics before invasive dental procedures. This helps prevent endocarditis, a serious heart infection often caused by bacteria from the mouth.

For heart attack survivors, taking a polypill that contains a blood pressure drug, a cholesterol-lowering statin, and low-dose aspirin may help prevent more future heart attacks and serious heart problems than usual care that includes several separate drugs.

Vegetable "steaks" made from sliced eggplant, cauliflower, squash, or other vegetables can provide a vegetarian option at holiday dinners. Top roasted vegetables with cheese, nuts, herbs, or sauce.

Having a dog or another pet appears to lower the risk of high blood pressure and improve blood pressure control. Pet ownership may foster positive feelings (such as decreased stress) and habits (such as daily walks) that may improve heart health. People who own dogs walk about 20 minutes more per day on average than those without dogs. Pets can help combat loneliness and social isolation, which have been linked to a higher risk of heart attack, stroke, or death from these causes.

Palpitations, which are defined as an awareness of an abnormal heartbeat, can feel as though the heart is skipping, flip-flopping, or racing. These heart "hiccups" are usually harmless, such as those that result from a small surge of adrenalin that causes the heart to beat faster or more forcefully than usual. But some unusual heart rhythms warrant closer attention, especially if they occur in tandem with symptoms such as feeling lightheaded, dizzy, or faint.

Dry-roasted assorted nuts are a heart-healthy alternative to traditional holiday sweets. They contain unsaturated fats that help lower harmful LDL cholesterol and inflammation—two key culprits in cardiovascular disease. Nuts are also a decent source of protein, which helps people feel full and may prevent overeating. They contain fiber (which may also reduce cholesterol and increase satiety) as well as several vitamins, minerals, and plant compounds that help counteract inflammation and oxidation, another artery-damaging process implicated in heart disease.

A heart murmur is the sound of turbulent blood flow within the heart as heard through a stethoscope. In adults, most abnormal murmurs are caused by an aortic or mitral valve that's not working correctly.
