People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

People can learn how to give chest compressions—a key aspect of cardiopulmonary resuscitation, or CPR—by watching a 90-second online video. CPR keeps blood flowing to the brain and vital organs during a cardiac arrest. There are various ways to practice chest compressions on a mannequin, including at an in-person class or at one of 30 kiosks (including six at major airports) located nationwide.

Snow shoveling can be risky for people with heart disease because (1) the activity requires a lot of physical effort, and (2) cold temperatures constrict arteries. Both factors can raise the risk of a heart attack in people with narrowed heart arteries.

Most hospitals have chaplains who can provide emotional and spiritual support to patients and their families during challenging medical situations, such as impending heart surgery, a worsening bout of heart failure, or cardiac arrest. Spiritual care, which has been linked to improved health outcomes, encompasses but does not necessarily include formal religious practices. It aims to help people explore sources of comfort and hope while coping with the challenge of a diagnosis.

For stroke survivors, workouts that alternate high- and low-intensity exercise (known as high-intensity interval training or HIIT) may boost fitness more than moderate-intensity workouts.

An online tool to predict heart disease risk might be more accurate if it included a psychological health assessment. Including depression screening results appears to strengthen the tool's ability to predict heart disease deaths.

Over a 24-year span, people whose diets favored plant-based fat lived longer than people who ate more animal-based fat, according to a 2024 study. The same distinction appeared specifically for deaths from heart disease.

In 2024, the FDA approved two catheter-based devices for treating a leaky tricuspid valve. Both relieve symptoms and improve quality of life for people with moderate to severe tricuspid regurgitation, which affects about 4% of people ages 75 and older. One device is a modification of a system to treat mitral valve regurgitation that works by bringing the valve leaflets together at the areas of most severe leakage. The other device delivers a new valve made of cow heart tissue, which is commonly used in surgical valve replacements.

People sometimes wonder if the calcium they consume affects their calcium score, a test that measures calcium in the heart's arteries to predict heart disease risk. But a 2024 study linked higher calcium intake to a lower risk of heart calcifications. Calcium helps lower blood pressure, possibly by improving the function of the lining of blood vessels. Older adults should make sure they're getting the recommended amount of calcium in their diets. Good sources include dairy products, tofu made with calcium sulfate, almond or oat milk, canned sardines or salmon, collard greens, and kale.

Renal denervation, a nondrug treatment for uncontrolled high blood pressure, works by disrupting some of the nerves surrounding the renal arteries, which supply the kidneys. Two systems are FDA-approved for people whose blood pressure remains high despite lifestyle changes and medications. Renal denervation lowers systolic blood pressure by an average of 8 to 9 points—about the same as what people get with a single blood pressure drug. But the response varies widely; some people experience more dramatic drops, while others have no response.
