The cause of the vast majority of heart attacks is the rupture of atherosclerotic plaque within the coronary arteries (arteries that supply blood to the heart muscle itself). Plaque rupture occurs silently in many instances, where the rupture either is NOT followed by clot formation within the coronary artery or where the clot quickly dissolves. In fact, the typical heart attack occurs in the following sequence: 1) plaque rupture; 2) clot formation; 3) clot persistence; and finally 4) death of heart muscle. Following plaque rupture, whether leading to a heart attack or not, healing of the plaque occurs over time with deposition of calcium. The presence of calcium within the walls of the coronary arteries thus indicates that plaque rupture occured at some point in the past. And, having had plaque rupture obviously indicates the presence of plaque, atherosclerosis and cardiovascular disease. At The Heart Attack Prevention Institute (HAPI) of Naples, FL, patients have the convenience of obtaining coronary calcium score (CCS) testing at an independent radiology facility (ProScan Imaging) located right next door.
