The most common form of heart disease, coronary artery disease, is usually caused by the buildup of plaque in the heart’s major blood vessels, limiting blood flow to the heart that could result in chest pain (angina) or heart attack. In the early stages of disease, there may be no symptoms. Many people don’t realize they have coronary artery disease until a health crisis makes them aware.
Coronary calcium scoring (heart scan) is a way to detect coronary artery disease in an early stage before symptoms arise using a computed tomography (CT) scan to detect the buildup of calcium on the walls of the arteries of the heart (coronary arteries). The presence of calcium indicates that there may be plaque in the coronary artery that can limit or block blood flow to the heart.
Your doctor may use the information from this exam to determine a course of treatment to help reduce your risk for a heart attack in the future.
