Using a Web-based app, most people can correctly assess their need for a cholesterol-lowering statin and take the drug appropriately with good results, according to a 2024 study. If approved, the app could facilitate statin use without a doctor's prescription.

A 2024 study suggests using cannabis weekly may be associated with an increase in people's risks of heart attack and stroke, and the risks rise dramatically with more frequent use.

Older adults might be able to lower their blood pressure by reducing their sitting time by as little as 30 minutes per day, according to a 2024 study.

The American Heart Association's first-ever scientific statement on artificial intelligence (A.I.) in cardiology explores how the technology may improve how doctors prevent, detect, and treat heart disease. For example, A.I. data from patch monitors may predict who will develop potentially serious heart rhythms. Applying A.I. tools to a single chest x-ray may predict a person's risk of heart attack and other serious health problems.

People who have or are at risk for cardiovascular disease should be extra cautious when exercising outside when it's hot, humid, and hazy, as they are more vulnerable to the hazards of high temperature and air pollution. To exercise safely during a heat wave, people should avoid being outside during the middle of the day; wear light-colored, lightweight clothing; and be careful to stay hydrated.

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.

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.

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.

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.
