There is some disparity in the morbidity and mortality rates of cardiovascular disease (CVD) according to race, ethnicity, and geographicregions. Although prediction algorithms that evaluate risk of cardiovascular events have been established using traditionalrisk factors, they have also demonstrated a number of differences along with race and ethnicity. Of various risk assessment modalities,coronary artery calcium (CAC) score is a sensitive marker of calcific atherosclerosis and correlates well with atheroscleroticplaque burden. Although CAC score is now utilized as a useful tool for early detection of coronary artery disease, prior studieshave suggested some variability in the presence and severity of coronary calcification according to race, ethnicity, and/or geographicregions. Among Asian populations, it would appear necessary to reappraise the utility of CAC score and whether it remainssuperior over and above established clinical risk prediction algorithms. To this end, the Korea initiatives on coronary arterycalcification (KOICA) registry has been designed to identify the effectiveness of CAC score for primary prevention of CVD in asymptomaticKorean adults. This review discusses the important role of CAC score for prognostication, while also describing thedesign and rationale of the KOICA registry.

Coronary artery disease (CAD) is the leading cause of mortality worldwide, and various cardiovascular imaging modalities havebeen introduced for the purpose of diagnosing and determining the severity of CAD. More recently, advances in computed tomography(CT) technology have contributed to the widespread clinical application of cardiac CT for accurate and noninvasive evaluationof CAD. In this review, we focus on imaging assessment of CAD based upon CT, which includes coronary artery calciumscreening, coronary CT angiography, myocardial CT perfusion, and fractional flow reserve CT. Further, we provide a discussion regardingthe potential implications, benefits and limitations, as well as the possible future directions according to each modality.
