Coronary computed tomography: Current role and future perspectives for cardiovascular risk stratification

Abstract

Atherosclerotic coronary artery disease (CAD) is a major cause of morbidity and mortality. The majority of cardiovascular events, more than 50% of CAD deaths, occur in previously asymptomatic individuals at intermediate cardiovascular risk, highlighting the relevance of accurate individual risk assessment to decrease cardiovascular events through more appropriate targeting of preventive measures. In the last decades, the development of non-invasive imaging techniques have prompted interest in imaging of atherosclerosis. Coronary computed tomography provides the opportunity to assess the deposition of calcium in the coronary tree and to non-invasively image coronary vessels. Both information are useful for risk stratification of asymptomatic subjects or of subjects with suspected CAD.
