The coronary arteries supply blood to the heart muscle. Cholesterol and calcium can deposit plaques on the walls of these vessels, reducing the amount of blood that can flow through them. This is known as atherosclerosis , literally hardening (sclerosis ) of the arteries (athero ). Lack of enough blood to the heart muscle may cause chest pain, which is usually described as a pressure sensation in the front of the chest. Patients often say it feels like “an elephant sitting on my chest.” Pain may also be felt in the left arm. When there is a severe shortage of blood supply to the heart, some of its muscle may die, causing a heart attack (myocardial infarction ). The November 7, 2012, issue of JAMA is a theme issue on cardiovascular disease.
