People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.

About 98 million Americans have prediabetes, in which the average amount of sugar (glucose) in the blood is high but not high enough to be diagnosed as diabetes. While people with prediabetes want to avoid getting diabetes, prediabetes can be dangerous on its own, as it increases the risk for cardiovascular disease, chronic kidney disease, and fatty liver disease. Controlling blood pressure, lowering LDL (bad) cholesterol, and managing glucose levels with weight loss, exercise, and diet offers protection against diabetes and these conditions.

For stroke survivors, workouts that alternate high- and low-intensity exercise (known as high-intensity interval training or HIIT) may boost fitness more than moderate-intensity workouts.

People sometimes wonder if the calcium they consume affects their calcium score, a test that measures calcium in the heart's arteries to predict heart disease risk. But a 2024 study linked higher calcium intake to a lower risk of heart calcifications. Calcium helps lower blood pressure, possibly by improving the function of the lining of blood vessels. Older adults should make sure they're getting the recommended amount of calcium in their diets. Good sources include dairy products, tofu made with calcium sulfate, almond or oat milk, canned sardines or salmon, collard greens, and kale.

A 2024 study suggests that swapping table salt for a salt substitute can markedly lower the risk of developing high blood pressure.

An online tool to predict heart disease risk might be more accurate if it included a psychological health assessment. Including depression screening results appears to strengthen the tool's ability to predict heart disease deaths.

In 2024, the FDA approved two catheter-based devices for treating a leaky tricuspid valve. Both relieve symptoms and improve quality of life for people with moderate to severe tricuspid regurgitation, which affects about 4% of people ages 75 and older. One device is a modification of a system to treat mitral valve regurgitation that works by bringing the valve leaflets together at the areas of most severe leakage. The other device delivers a new valve made of cow heart tissue, which is commonly used in surgical valve replacements.

Air travel tips for people who have or are at risk for heart disease include bringing extra prescription medications in a carry-on bag and drinking water-but not alcohol-during the flight. When taking medications (especially blood pressure and anti-clotting drugs), people should try to schedule their doses based on their home time zone. On a long flight, walking a little every hour or so will help improve circulation in the legs; so can flexing the feet and circling the ankles. Doing so may reduce the chance of developing a blood clot, although the overall risk of such clots (known as deep-vein thrombosis) is quite low.

Leadless pacemakers, which are no bigger than a multivitamin pill, are far less prone to complications that traditional pacemakers, which have long leads (wires). These wires may become infected, dislodged, frayed, or broken. Scar tissue or blood clots can form around the leads, which may hinder blood flow and cause pain and swelling. Thanks to recent advances, most people who need pacemakers may now be candidates for leadless devices. However, doctors have less experience with what happens with leadless pacemakers over the long term-and they cost two to three times as much as a traditional pacemaker.
