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.

When choosing a home blood pressure monitor, people should select one that has an easy-to-read display and a well-fitting upper arm cuff that inflates automatically. It should appear on the U.S. Blood Pressure Validated Device Listing.

RNA-targeted drugs work by preventing the synthesis of proteins involved in different diseases. One, called inclisiran (Leqvio), dramatically lowers LDL cholesterol with just two injections per year. Additional RNA-targeted drugs to lower elevated lipoprotein (a) and high blood pressure are currently in late-stage clinical trials.

Migraines and cardiovascular disease share certain common features, including changes in blood vessels, blood flow, and inflammation. Migraine with aura is linked to an increased risk of stroke, and common migraine drugs called triptans are linked to a higher risk of stroke and heart attack in people at risk for cardiovascular disease. Although both of these risks are extremely small, migraine sufferers with heart-related risks should seek out a personalized approach for treatment and know the warning signs of a stroke.

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 suggests that younger women with migraines and early menopause symptoms such as hot flashes and night sweats may have higher cardiovascular risks at midlife.

People with atrial fibrillation (afib) worry that drinking alcohol or caffeine might trigger a flare-up of the condition. Afib is characterized by erratic beating of the heart's two upper chambers. The chambers quiver, causing blood to pool and sometimes form clots, which can cause a heart attack or stroke. Evidence strongly suggests that drinking alcohol can cause a flare-up of afib. Drinking caffeine in usual amounts does not increase that risk. However, doctors note that people who are especially sensitive to caffeine should avoid it.

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.

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.

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.
