People with very high calcium scores (over 1,000) have a risk of heart attack or stroke similar to those who have already had a heart attack. They should take cholesterol-lowering drugs to bring down LDL levels and possibly undergo additional testing.

Direct-to-consumer genetic tests can screen for rare heart conditions that arise from variants in a single gene (such as cardiomyopathies) as well as common conditions influenced by many thousands of gene variants (such as coronary artery disease). But because the results are not definitive, they can be challenging to interpret.

Fatty plaque that accumulates in the arteries of the legs, known as peripheral artery disease (PAD), can cause a painful, crampy sensation in the legs during walking. Smoking, obesity, diabetes, high blood pressure, and elevated cholesterol increase the risk of PAD, which affects nearly one in three people over age 75. Beyond quitting smoking, regular walking is the best treatment for PAD. A 2025 study found that semaglutide (Ozempic, Wegovy) may help people with PAD walk farther with less pain.

A healthy diet is a proven and powerful way to lower your risk of heart disease. Since dinner is often the main meal of the day, it's a good time to feature foods that support cardiovascular health. Four Harvard physicians share their favorite healthy dinners, which focus on lean protein (such as tofu, fish, and chicken) and a variety of vegetables.

A 2025 study found that a pill version of the drug semaglutide, marketed as Rybelsus, can lower the risk for serious heart problems in people who have diabetes as well as cardiovascular disease, kidney disease, or both.

A regular yoga practice may help people shed pounds while also improving their heart health. A form of low- to moderate-intensity aerobic exercise, yoga also stretches and strengthens muscles. A 2025 review article suggests that yoga can decrease body mass index, waist circumference, and body fat percentage while also improving blood pressure and cholesterol values.

A 2025 study suggests that squeezing a week's worth of exercise (150 minutes) into just one or two days - a "weekend warrior" pattern - is linked to the same heart benefits as daily exercise.

A 2025 study found that chronic stress is associated with higher stroke risks among women under 50, but not in men.

Cannabis use is rising among older adults, who mostly use cannabis edibles such as gummies for relaxation and sleep. While smoking cannabis may raise heart attack risk, the cardiac effects of consuming cannabis in food or drinks are less well understood. Taking too much cannabis can lead to a panic attack, which can cause a pounding heart or palpitations. People who use cannabis should take it only as needed to relieve symptoms, using the lowest possible dose.

Wildfire smoke contributes greatly to poor air quality, and as wildfires become more frequent due to climate change and drier conditions, more of us and more of our communities are at risk for health harms. Here are ways to cope.
