Heart attack: if you want to decrease your risk, get on a Mediterranean diet and exercise program and see your doc to take care of treatable risk factors, don 't smoke and good luck for a healthy future.

Very rare: And when it does, its usually related to exceptional family history of early heart disease or in patients with drug abuse like cocaine. But your elevated BMI and lacknof physical activity are risk factors for vascular disease in the future, so try to do your best to work on these issues.
