Abstract
Coronary artery disease (CAD) is associated with substantial morbidity and mortality worldwide. Despite many advances in prevention and therapy for CAD, a third to one-half of cardiovascular events occur in those with no prior symptoms. Assessing subclinical disease using coronary artery calcium (CAC) has been shown to provide additional risk stratification and to improve prediction of cardiovascular events over traditional strategies such as the Framingham Risk Score. In this review, we aim to cover the current data available on utilization of CAC as a tool in the general population as well as in targeted subgroups such as those with diabetes and metabolic syndrome. For this review, the authors performed thorough Pubmed and Medline searches using keywords coronary artery calcification, X-ray computed tomography, multidetector computed tomography, CAD, diabetes mellitus and metabolic syndrome. Based on the authors' review of literature, they believe that CAC is an excellent risk stratification imaging modality, especially in patients with diabetes and metabolic syndrome; behavioral changes in patients and therapeutic interventions based on CAC scoring are cost-effective.
