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.

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.

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.

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.

Health insurance companies sometimes require prior authorization for new, expensive medications. The high price patients pay for these drugs is related to complexities in health insurance coverage.

A large observational study published in 2024 suggests that stroke isn't the biggest risk of atrial fibrillation (an abnormal heart rhythm condition). The biggest risk seems to be heart failure, a condition in which the heart is unable to pump blood effectively.

Cardiac rehabilitation, a personalized program of supervised exercise and heart-healthy lifestyle coaching, helps people recover from heart-related problems, including stable angina, heart attack, heart surgery, and stable heart failure. A 12-week program helps people regain their stamina, enabling them to resume their favorite activities, and may also lessen stress and depression. Cardiac rehab is also proven to lower the risk of future heart-related illness and hospitalization and may help people live longer.

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 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.
