What is a “Heart Scan”(CT calcium score, coronary artery calcification scoring (CACS))?
Calcium scoring is a new non-invasive tool to test for coronary artery disease. This 5-minute exam uses CT scans to look for calcium deposits in the coronary arteries. Calcium is a component of arterial plaque, the fatty build up that causes atherosclerosis by sticking to artery walls. When this plaque constricts blood flow, it leads to heart attacks.
