A large waistline — 35 inches or more in women or 40 inches or more in men — can signal the presence of visceral fat. Located deep within the abdominal cavity, visceral fat pads the space around the organs and is closely linked to cardiovascular problems. Getting regular exercise (both aerobic and strength-based) and following a healthy, reduced-carbohydrate diet can help reduce visceral fat. Time-restricted eating may also help.

Walk with a Doc is a nonprofit program founded by a cardiologist that sponsors free, doctor-led walks in mostly outdoor venues (usually public parks) in 560 sites across America. The walks last 30 to 90 minutes, are usually held once per month, and include a five-minute talk about various health topics by the physician. In addition to the exercise and education, participants benefit from the camaraderie and time spent in nature.

Diets high in added sugars are linked to an increased risk of coronary artery disease, but naturally occurring sugars in fruits and vegetables are not. Nearly 70% of added sugar in the American diet comes from sugary beverages, desserts and sweet snacks, candy, and breakfast bars and cereals. Consuming excess added sugar promotes weight gain and diabetes and also spurs the liver to pump out triglycerides and other fats into the bloodstream.

Taking supplements that contain high levels of biotin (vitamin B₇) can lead to falsely low or falsely high results on a troponin test, a blood test used to diagnose heart attacks.

Blood thinners don't "thin" blood; rather, they discourage blood from clotting. Candidates for anti-clotting drugs are people at high risk for dangerous blood clots, such as those with atrial fibrillation or those who have received a stent. Others who can benefit from an anti-clotting drug are people who are immobile after surgery and individuals who have had deep-vein thrombosis (clots in the veins of the legs or arms) or pulmonary embolism (clots in the lungs). A higher risk of bleeding is the main side effect, but most people can tolerate the medication.

Dietary choices can influence weight, blood pressure, cholesterol levels, and blood sugar levels, all factors that can determine a person's risk for heart disease, heart attack, and stroke. Adopting certain eating habits can help manage these factors. These include reducing the intake of saturated fat and refined sugar that are included in many processed foods, eating more healthy monounsaturated and polyunsaturated fats, and following a plant-based diet like the Mediterranean or DASH diet.

Men who report specific types of job-related stress face a higher risk of heart disease than those without such stress, according to a 2023 study.

Older adults who take medications to lower their blood pressure may reduce their risk of dementia, according to a 2023 study. The finding reinforces the connection between heart and brain health.

A 2023 study suggests that a "weekend warrior" exercise pattern, in which people concentrate their exercise into one or two days weekly, can lower cardiovascular risks as effectively as a pattern of spreading exercise out over the week.
