Heart disease and poor diet. Artwork of an obese man eating fatty and fried foods while having his blood pressure monitored. The broken heart symbol (upper left) represents heart disorders that can result from a poor diet such as the one shown here. Coronary heart disease, a form of atherosclerosis (fatty deposits accumulating in the arteries), can block the coronary arteries and lead to a heart attack (myocardial infarction). Smoking (cigarette at lower left) is also a risk factor for heart disease and other conditions such as lung cancer.
