Using tobacco in cigars, pipes, or smokeless products such as snuff is associated with distinct heart-related risks.

Strokes fall into two main categories: ischemic (which result from a blockage inside one of the brain's arteries and account for 87% of all strokes) and hemorrhagic (also known as bleeding strokes, usually from a ruptured blood vessel). Three main types of ischemic strokes are those that result from atherosclerosis in a large artery supplying the brain (large-artery atherothrombotic strokes); those caused by clots in the heart that travel to the brain (cardioembolic strokes); and those in the brain's smallest vessels (small-vessel strokes).

A 2024 study involving more than 72,000 healthy people ages 40 to 79 found that those whose sleep and wake times fluctuated most had a 26% higher risk of having a heart attack, stroke, or similar problem, compared with those whose sleep patterns fluctuated least.

A gluten-free diet (which omits wheat, rye, and barley) may be low in fiber, a nutrient that's important for cardiovascular health. People who avoid gluten should try to include gluten-free grains and seeds in their menus, such as amaranth, buckwheat, millet, sorghum, teff, and quinoa. Carrots, celery, kale, and kiwis contain mostly insoluble fiber, which helps you feel full and encourages regular bowel movements. Beans, nuts, seeds, and fruits (such as berries, apples, pears, and citrus fruits) are good sources of soluble fiber, which helps lower cholesterol and blood sugar.

About two-thirds of people over 65 have periodontal disease, which is linked to a higher risk of heart disease. Shared risk factors such as smoking and an unhealthy diet may explain the association, but bacteria and inflammation could be a common thread. The bacteria responsible for periodontal disease can travel to blood vessels throughout the body and have been found in the fatty debris (atherosclerosis) that clogs arteries located far from the mouth—and in blood clots from people who have experienced heart attacks.

A 2024 study of more than 200,000 adults, combined with findings from 19 other studies (for a total of 1.25 million people), tied eating ultra-processed foods—particularly sugary drinks and processed meats—to an increased risk for heart disease.

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.

The Brain Care Score is a quiz developed to help people identify proven, actionable steps to lower their risk of stroke, dementia, and depression. It includes four physical components (blood pressure, blood sugar, cholesterol, and body mass index); five lifestyle components (nutrition, alcohol intake, smoking, aerobic activities, and sleep); and three social-emotional components (stress management, social relationships, and meaning in life). Each response is given a point value, with the highest possible score totaling 21. Higher scores mean better brain care.
