Low-value care (tests or procedures that offer no clear benefit) is a particular problem for people with cardiovascular disease. Low-value care may happen because certain tests are widely available and may provide financial benefit to the health care center. But for patients, these tests may be a waste of time and money and lead to anxiety and risky complications. Up to half of all exercise stress tests and 15% of stent placements done in the United States may be inappropriate.

Doing 30 to 60 minutes per week of strength training exercises is linked to a lower risk of premature death in general, and from heart disease in particular. Regular strength training may improve heart health by lowering the risk of blood pressure and metabolic syndrome. Body-weight exercises such as standing lunges and bench push-ups are a convenient way to build muscle because they can be done anywhere, without the need for special exercise equipment.

COVID survivors—even those with mild infections—appear to face a higher risk of cardiovascular problems such as heart failure, heart attack, and stroke for up to one year after their initial infection. People who were hospitalized (especially those who ended up in the intensive care unit) may have the highest risk. The virus that causes COVID can injure blood vessels and triggers an immune response that promotes the formation of blood clots in arteries and veins throughout the body and brain.

Regular walking—for at least 30 minutes a day, three days per week—is the best treatment for peripheral artery disease. This condition is characterized by fatty deposits that accumulate in arteries outside the heart and brain (usually the legs). Walking encourages blood flow in the leg's smaller arteries and also creates new channels that move blood around the blocked areas, which eventually helps ease the pain.

The long-held assumption that light to moderate drinking is good for a person's heart is likely inaccurate. A new study using sophisticated genetic tools suggests that the risk of high blood pressure and coronary artery disease rise for any quantity of alcohol consumption. The added risk is low when people consume up to a single drink per day but rises exponentially at levels above seven drinks per week. This added risk applies to a first-time diagnosis of heart disease and not to people already diagnosed with a heart problem (who might well face even greater risk).

High blood pressure increases the risk of stroke and plays a role in cognitive decline. Simple lifestyle changes such as eating a healthy diet, exercising, and losing weight can lower blood pressure.

In a study published online Feb. 14, 2022, by the journal Heart, people ages 65 or older who exercised at least 20 minutes per day—especially men ages 70 to 75—had fewer heart attacks and a lower risk of premature death, compared with people who didn't exercise.

Two important types of fat in the body are white fat and brown fat. White fat is located in the chest, abdomen, and upper legs; too much of it constitutes obesity. Its function is to provide insulation against the cold, store fats derived from food, and continually release small amounts of the fats to be converted into energy. Brown fat is found in small amounts in the neck, shoulders, chest, and abdomen. Its main function is to burn the fat it stores, creating heat that keeps the body warm.

Physical activity monitors, such as smart watches and fitness trackers, may help people get more exercise, such as extra daily steps and more moderate-to-vigorous activity per week. But the long-term durability of this behavior change is unknown. Using a fitness tracker requires more than just moving more; people also have to remember to keep the tracker charged, wear it consistently, and check their data. But for some people, the day-to-day feedback on their progress may help keep them engaged.

Misperceptions and biases about obesity can derail progress against this common disease, which affects 42% of Americans and is linked to many serious health problems, including heart disease. Bias and stigma against people with obesity is widespread, often due to a belief that poor choices and lack of motivation are the only causes. But a number of interconnected factors are involved, including an obesity-promoting environment, lack of physical activity, genetics, insufficient sleep, mental health issues, and certain medications.
