CACS
Also written as: CACS — coronary artery calcium scoring
Coronary artery calcium scoring using CT imaging to assess atherosclerotic burden.
Full Definition
Coronary artery calcium scoring (CACS) is a non-invasive imaging technique that quantifies calcified atherosclerotic plaque in coronary arteries using computed tomography. The Agatston score is the most commonly used method, with scores of 0, 1-99, 100-399, and ≥400 representing absent, mild, moderate, and severe coronary calcification respectively. CACS is particularly useful for risk stratification in intermediate-risk patients and can guide decisions about statin initiation and treatment intensity.
