Device of the month: Home blood pressure monitor

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 for heart disease

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.

Migraine and cardiovascular disease: What's the link?

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.

How low should LDL cholesterol go?

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.

Will drinking alcohol or caffeinated drinks trigger my atrial fibrillation?

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.

When the heart suddenly starts racing

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.

Healthy European cuisines from beyond the Mediterranean

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.

Is niacin safe for the heart?

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.

Interval training: A shorter, more enjoyable workout?

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.

Keto diet is not healthy and may harm the heart

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.
