Many Americans may have a potentially serious condition marked by a buildup of fat inside the liver. Known as metabolic dysfunction-associated steatotic liver disease (MASLD), it's closely linked to a higher risk of cardiovascular disease. The root of the problem is usually excess weight-especially the accumulation of belly fat known as abdominal obesity. Weight gain can trigger a host of metabolic problems that cause blood sugar, blood pressure, and cholesterol levels to rise. All of these factors are closely linked to a higher risk of diabetes and cardiovascular disease. Heart disease is one of the common causes of death among people with MASLD.

Letting your arm dangle or rest in your lap (instead of being supported at heart level, as is recommended) during a blood pressure check can cause a falsely high reading, according to a 2024 study.

Implanted heart devices include pacemakers and implantable cardioverter defibrillators (ICDs), which monitor and correct abnormal heart rhythms. While very reliable, they are not perfect, and recalls of these devices affect thousands of people each year, according to a 2024 study. Testing the effectiveness and safety of cardiac devices is far more complicated than testing drugs. But efforts are under way to improve postmarket tracking of device complications by using electronic health records, Medicare databases, and registries developed in partnership with device manufacturers.

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.

U.S. guidelines define normal blood pressure as less than 120/80 millimeters of mercury (mm Hg). Studies have shown that the lower a person's blood pressure, the greater the heart health benefits. However, the "best" blood pressure number for someone depends on several factors, such as the person's health condition, lifestyle, family history, and personal goals. Depending on an individual's situation, a higher-than-normal number may be adequate.

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.

A 2024 study found that when air pollution levels decreased during a five-year period in Italy, so did hospitalizations for heart-related emergencies. The results suggest that reducing air pollution could lower the prevalence of heart disease.

Smart rings can do many of the same things a smart watch can, including heart rate monitoring, blood oxygen level measurement, and activity and sleep tracking.

Winter soups containing beans, seasonal vegetables (such as squash, greens, and root vegetables), and whole grains are rich in heart-protecting nutrients. All the ingredients include lots of fiber, which helps lower cholesterol and is filling without adding too many calories. Homemade soups can be made with far less sodium (which raises blood pressure) than the amount found in many store-bought and restaurant soups.
