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.

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.

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.

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.

High temperatures raise risk for heat exhaustion and heat stroke, and also stress the cardiovascular system, making the heart work harder. If you have a heart condition, here's how to keep cool and protect yourself when temperatures rise.

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.

The signs of early heart failure, which include fatigue, shortness of breath, and swollen ankles, are often dismissed. Recent developments in both the detection and treatment of heart failure may help ease the burden of this disease. The American Diabetes Association recommends that people with type 2 diabetes receive yearly blood tests for a common biomarker of heart failure. And the FDA recently expanded use of a diabetes drug proven to keep people with heart failure (even those without diabetes) out of the hospital and alive longer.

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.

Blood pressure should be measured at every health care visit, but home-based monitoring is even more important. High blood pressure raises the risk of heart attacks and stroke, but this risk correlates far more closely with home blood pressure readings than those done in a doctor's office. Many factors can affect the reading's accuracy, including leg and arm position and whether the person recently exercised, smoked, or consumed caffeine.
