coronary artery calcium score
A coronary artery calcium (CAC) score measures the amount of calcium in the coronary arteries, which supply blood to the heart muscle. Using a specialized CT scan, the test detects and quantifies calcium buildup that indicates the presence of atherosclerosis, or plaque. A higher CAC score suggests a greater risk of future heart problems like heart attacks, while a lower score indicates healthier arteries. This information helps doctors assess cardiovascular risk more accurately and make informed decisions about prevention and treatment strategies.
