A system of scoring coronary artery calcification, to assess the degree of atherosclerosis in asymptomatic patients and form the basis for drug therapy and advising lifestyle modification.
Agatston scores are based on the product of the area of calcium deposits and radiographic attenuation in Hounsfield units. Agatston scoring is most useful in asymptomatic patients with low- to intermediate risk of coronary atherosclerosis.
• Low risk 0 Agatston units–AU
• Moderate risk 100-400 AU
• High risk 1,000+ AU
