A 2024 nationwide poll suggests that one in four older adults takes aspirin regularly in hopes of preventing a heart attack or stroke, even though updated guidelines from 2019 advise against that practice in many cases.

High-dose niacin (vitamin B₃) is no longer recommended to improve cholesterol and triglyceride levels. Different forms of niacin, such as niacinamide (nicotinamide), are sold as supplements; the potential benefits and risks remain unclear.

People who are at high risk for cardiovascular disease can benefit from driving down "bad" low-density lipoprotein (LDL) cholesterol levels as low as possible to help reduce their risk for heart attacks and strokes. Guidelines recommend that people at high risk aim for LDL levels below 70 milligrams per deciliter (mg/dL). The general population should strive for levels below 100 mg/dL. Taking statins and adopting healthier lifestyle habits like following a plant-based diet and increasing exercise can help manage LDL levels.

A 2024 study found that people with microplastics in the plaque clogging their neck arteries were about four times more likely to have a heart attack or stroke than people with plastic-free plaque.

High-intensity interval training (HIIT) is a time-efficient way for people to improve their fitness and cardiovascular health. Even short bursts of high-intensity activity may trigger the release of mood-boosting brain chemicals. Traditionally, HIIT features 30 to 90 seconds of high-intensity effort followed by an equal or longer period of lower-intensity activity or rest. HIIT variations include fartlek (Swedish for "speed play"), which uses environmental cues to set intervals, and Tabata, which features 20-second intervals of intensity followed by 10-second recovery intervals.

Direct-acting oral anticoagulants (so-called "blood thinners") are prescribed to treat atrial fibrillation, deep-vein thrombosis, or blood clots in the lung. Doctors also prescribe antiplatelet drugs to prevent blood clots in arteries that can lead to heart attacks or strokes.

In addition to the Mediterranean diet, other European eating patterns-namely, the Nordic diet and the Atlantic diet-feature heart-healthy fare. All three diets feature seafood, vegetables, fruits, whole grains, legumes, and nuts, with an emphasis on seasonal and local foods. Such foods also support environmental health and sustainability. People in the United States can follow this trend by shopping at a farmer's market or joining a community-supported agriculture program.

Paroxysmal supraventricular tachycardia is caused by an electrical glitch in the heart's upper chamber that causes the heart rate to suddenly soar for no apparent reason-sometimes as high as 200 beats per minute. The condition, which people describe as palpitations or a fluttering sensation in the chest, is usually not dangerous. But long-lasting bouts can lead to lightheadedness, breathlessness, and fainting.

According to a 2024 review, the ketogenic (keto) diet-which is high in fat and protein and low in carbohydrates-doesn't meet standards for a healthy diet and may not be safe for some people with heart disease.

Sleep problems such as insomnia, sleep apnea, and periodic limb movements can disrupt sleep. A lack of sleep or fragmented sleep can prevent people from getting enough restorative deep sleep and may cause unhealthy blood pressure surges. These problems may increase the risk of cerebrovascular disease (including stroke and unrecognized silent strokes) and cognitive issues.
