Human heart with diseased coronary arteries from atherosclerosis. This resin cast of the coronary arteries from the heart of an older person suffering from atherosclerosis shows the coronary arteries narrowed and unhealthy, indicating that blood is not reaching some parts of the heart. Atherosclerosis is a primary cause of heart disease, heart attack (myocardial infarction), and chest pain (angina). Compare this view with a healthy heart in 450616.
