What is a Coronary Artery Calcium (CAC) score? A CAC score measures the amount of calcium in the walls of the coronary arteries, which are the blood vessels that supply blood to the heart. CAC is measured using a non-invasive CT scan. A higher CAC score indicates a greater buildup of calcium, which is a sign of atherosclerosis (plaque buildup in the arteries). Calcium gets deposited in the artery wall, which contributes to the formation of more complicated, older plaques as part of the healing and stabilization process. Atherosclerosis increases the risk of heart attack, stroke, and other cardiovascular events. How is CAC scoring used to assess cardiovascular risk? CAC scoring assesses cardiovascular risk by providing additional information about the presence and extent of atherosclerosis beyond traditional risk factors. While traditional risk factors like age, sex, cholesterol levels, and blood pressure can estimate the likelihood of developing cardiovascular disease, CAC scoring directly visualizes the presence of plaque in the arteries. A CAC score of 0 indicates the absence of detectable plaque, generally associated with a low risk of cardiovascular events in the near future. Conversely, a CAC score above 0 suggests the presence of plaque, and the higher the score,...
