A 2025 study found that a new type of medication may safely slow the progression of aortic stenosis (narrowing of the aortic valve) and delay the need for valve replacement.

Older people with atrial fibrillation are sometimes advised to stop taking clot-prevention drugs due to fears about bleeding. But a 2025 study suggests that the risk of stroke and heart attack from stopping the drugs outweighs the risk of bleeding.

A 2025 studyfound that intermuscular fat-fat stored within muscle tissue-may increase a person's risk of heart disease.

Coronary computed tomography angiography (CCTA) creates a 3D image of the heart and its blood vessels, revealing both obstructive and nonobstructive plaque. Most heart attacks occur when smaller, nonobstructive plaques rupture and form a clot that triggers a heart attack. Used to assess people with stable angina, CCTA may prevent heart attacks by improving how cardiologists find and treat heart disease.

To optimize cardiovascular health, the best strategy may be a workout that combines three types of exercise: moderate-intensity aerobic exercise, vigorous-intensity aerobic exercise, and strength training. Moderate activity burns calories and boosts metabolism, which helps control weight. Moderate-to-vigorous exercise also helps dampen the body's "fight or flight" response, which plays a role in chronic stress and anxiety. Aerobic exercise in general also helps the heart to become more efficient and blood vessels to become more flexible. Strength training makes the body more efficient at burning fat for energy and helps improve insulin sensitivity.

People with a family history of heart disease and high LDL cholesterol should consult their doctor about lowering their LDL levels to less than 70 milligrams per deciliter, which often means taking a statin, eating a healthier diet and exercising regularly.

TV medical dramas often portray treatments for heart attacks and cardiac arrest. While the timelines are often accelerated and certain aspects may be dramatized to engage viewers, the medical details are, for the most part, factual and authentic. Writers and producers routinely rely on health care experts - including Harvard doctors - to make sure the information is accurate. For people with heart disease, seeing how emergency physicians treat urgent conditions may show them what to expect.

Cancer survivors are more likely to die of heart disease than from cancer-related complications. One reason is that certain cancer treatments can cause cardiovascular complications. But the two diseases share many root causes, including tobacco use and obesity, as well as diabetes and high cholesterol. Growing evidence suggests that people with heart disease may be more likely to develop cancer.
