Ignoring the warning signs of a ministroke can lead to a major stroke at a later time. People should be evaluated right away for symptoms such as speech and vision problems or weakness in an arm or leg.

Research into the health benefits of alcohol has not provided a clear answer. Some findings suggest that alcohol helps protect against heart disease and lowers the risk of heart attacks and strokes, and drinkers tend to live longer than nondrinkers. Other studies say these benefits are less clear. If you don't drink alcohol now, there are no health reasons to start drinking. If you do enjoy it, it's best to have no more than 2 drinks in the same day.

A 2023 study suggests that sleep problems such as snoring, snorting, or getting too much or little sleep can significantly raise the odds of having a stroke.

Peripheral artery disease (PAD), which occurs when fatty deposits clog arteries outside the heart, is underrecognized and potentially dangerous. The hallmark symptom is leg pain that occurs with exercise, called intermittent claudication. PAD is more common among people who are older, who smoke, and who have diabetes. The recommended treatment involves short periods of walking interspersed with rest periods when pain occurs. Walking increases blood flow in the leg's smaller arteries and helps create new channels to move blood around the blockages; it also helps discourage new blockages.

Most strokes are caused by a clot that blocks a blood vessel in the brain. Those that damage small areas of brain tissue that don't control any vital functions are known as silent strokes because they don't cause any noticeable symptoms.

The more salt people eat, the greater their risk of clogged heart and neck arteries, a 2023 study suggests. Narrowed arteries (atherosclerosis) can lead to heart attacks and strokes.

COVID-19 may increase the risk of cardiovascular problems, including heart attack, stroke, pulmonary embolism, atrial fibrillation, and heart failure, up to a year after the infection. But vaccination appears to lower these risks. Getting just one dose of a COVID vaccine may halve the risk of myocarditis, a rare condition that causes inflammation of the heart muscle that can arise after viral infections.

Marijuana use, which is rising among older adults, appears to heighten the risk of heart-related problems. Cannabis is known to increase heart rate and blood pressure, although high doses can have the opposite effect. Marijuana use has been implicated in causing heart attacks, atrial fibrillation, stress cardiomyopathy, and arteritis.
