Fewer than half of people who experience cardiac arrest outside of a hospital receive CPR from someone nearby. Shorter, more accessible training and help from technology may encourage more people to learn and administer this lifesaving technique. Another potential barrier to performing CPR is not recognizing the symptoms of cardiac arrest. Common mistakes include pressing down on the stomach instead of the center of the chest, not compressing the chest deeply enough, or giving compressions that are either too fast or too slow.

A 2022 study found that people who have depression after a heart attack are nearly 50% more likely to suffer a stroke compared with heart attack survivors who don't develop depression.

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.

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.

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.
