When choosing a home blood pressure monitor, people should select one that has an easy-to-read display and a well-fitting upper arm cuff that inflates automatically. It should appear on the U.S. Blood Pressure Validated Device Listing.

High-intensity interval training (HIIT) is a time-efficient way for people to improve their fitness and cardiovascular health. Even short bursts of high-intensity activity may trigger the release of mood-boosting brain chemicals. Traditionally, HIIT features 30 to 90 seconds of high-intensity effort followed by an equal or longer period of lower-intensity activity or rest. HIIT variations include fartlek (Swedish for "speed play"), which uses environmental cues to set intervals, and Tabata, which features 20-second intervals of intensity followed by 10-second recovery intervals.

Direct-acting oral anticoagulants (so-called "blood thinners") are prescribed to treat atrial fibrillation, deep-vein thrombosis, or blood clots in the lung. Doctors also prescribe antiplatelet drugs to prevent blood clots in arteries that can lead to heart attacks or strokes.

In addition to the Mediterranean diet, other European eating patterns-namely, the Nordic diet and the Atlantic diet-feature heart-healthy fare. All three diets feature seafood, vegetables, fruits, whole grains, legumes, and nuts, with an emphasis on seasonal and local foods. Such foods also support environmental health and sustainability. People in the United States can follow this trend by shopping at a farmer's market or joining a community-supported agriculture program.

People with atrial fibrillation (afib) worry that drinking alcohol or caffeine might trigger a flare-up of the condition. Afib is characterized by erratic beating of the heart's two upper chambers. The chambers quiver, causing blood to pool and sometimes form clots, which can cause a heart attack or stroke. Evidence strongly suggests that drinking alcohol can cause a flare-up of afib. Drinking caffeine in usual amounts does not increase that risk. However, doctors note that people who are especially sensitive to caffeine should avoid it.

High-dose niacin (vitamin B₃) is no longer recommended to improve cholesterol and triglyceride levels. Different forms of niacin, such as niacinamide (nicotinamide), are sold as supplements; the potential benefits and risks remain unclear.

A thoracic aortic aneurysm (a weakened area in the wall of the upper section of the aorta) may require surgical repair if it grows too large. Aneurysms in the area called the descending aorta can sometimes be repaired with a less invasive endovascular technique.

People who routinely exercise far more than the federal activity guidelines recommend will likely reap heart and longevity benefits. But they should be sure not to neglect other heart-healthy habits, such as getting routine check-ups, keeping tabs on their risk factors, following a healthy diet, and paying attention to heart-related symptoms.

Sleep problems such as insomnia, sleep apnea, and periodic limb movements can disrupt sleep. A lack of sleep or fragmented sleep can prevent people from getting enough restorative deep sleep and may cause unhealthy blood pressure surges. These problems may increase the risk of cerebrovascular disease (including stroke and unrecognized silent strokes) and cognitive issues.

A heart rate below 60 beats per minute, called bradycardia, is fairly common in people older than 70. The most common permanent cause is age-related degenerative changes in the heart's conduction system. Previous heart problems, including a heart attack or heart surgery, make the problem more likely. Medical issues including sleep apnea, hypothyroidism, and certain medications can also cause bradycardia. People experiencing a low heart rate and symptoms such as feeling dizzy, lightheaded, fatigued, or breathless should seek medical care right away.
