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.

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.

Having a home workout area can make it easier to meet daily exercise goals, especially during the winter months, when weather conditions may make outdoor exercise impractical. If space allows, people may want a treadmill or other machine that's suitable for any health issues they may have. For example, people with hip or knee arthritis often find that a stationary bike is more comfortable for arthritic joints. For strength training, resistance bands or tubes are ideal for beginners because they're affordable, versatile, and easy to use. Scheduling a few sessions with either a physical therapist or certified personal trainer can help people learn and practice proper form.

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.

Anti-obesity drugs, which can lead to dramatic weight loss, may improve symptoms of sleep apnea. This serious breathing disorder raises the odds of high blood pressure, heart attack, and stroke. Excess weight is the strongest risk factor linked with sleep apnea, which affects about 25% of men and 10% of women in the United States. Extra fat tissue in the neck and throat can narrow the airway, and extra weight on the chest and belly puts pressure on the lungs, which makes the normal process of inhaling and exhaling less effective.

Eating cruciferous vegetables like broccoli and cauliflower may reduce blood pressure more than eating squash and root veggies.

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.

The body roundness index—defined as height in relation to waist circumference—may be a good way to predict a person's risk of cardiovascular disease.

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.

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.
