About one in 11 men ages 65 and older has atrial fibrillation (afib), a heart rhythm disorder that causes an irregular and often faster-than-normal heartbeat. Afib can be persistent and chronic, or it can happen intermittently. People might have no symptoms with either variety, or afib can cause lightheadedness, shortness of breath, chest pain, or extreme fatigue. But the biggest worry is a fivefold increased risk of stroke. The main treatment choices for people are rate control with medication, or rhythm control, done with medication or a procedure such as electrical cardioversion or catheter ablation.

Some studies have found that drinking any amount of alcohol is unhealthy. But more than 100 large studies have found that people who have one drink per day have lower risks of cardiovascular disease. How can both be true? It depends on a person's current state of health, lifestyle habits (such as diet, exercise, and smoking), family history of disease, and the quantity of alcohol consumed. People who don't usually drink have no need to start: there are better ways to achieve a healthy heart.

Healthier alternatives to standard white pasta include spiralized vegetable "zoodles" (made from zucchini or yellow squash) as well as pasta made from whole-wheat flour, buckwheat flour, edamame (soybeans), chickpeas, or red lentils.

A 2022 study found that egg consumption equal to about one per day and greater dietary cholesterol intake were linked to a slightly higher risk of dying from cardiovascular disease.

A 2022 study suggests that using a smartwatch capable of estimating blood oxygen levels and recording an electrocardiogram could be an effective way to remotely monitor people at home following a minimally invasive heart valve replacement.

Emotionally stressful events that affect large numbers of people have been linked to an increase in heart attack rates. A 2022 study found the same correlation with a contentious political election.

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.
