South Asian (SA) individuals, particularly those that reside in the United States and other Westernized countries, are at an elevated risk for ASCVD and mortality related to ASCVD. The 2018 ACC/AHA/Multi-society Cholesterol guideline listed SA as a high-risk ethnicity, underscoring the importance of treating modifiable risk factors to reduce ASCVD burden. Coronary artery calcium (CAC), a highly specific marker of subclinical atherosclerosis, may be a useful test to improve risk stratification among SA individuals. CAC testing is a cost-effective, highly reproducible, and specific marker of subclinical atherosclerosis, shown to improve ASCVD risk assessment across all racial/ethnic groups, thereby serving as a guide for initiating or deferring preventive therapies. In this White Paper we will discuss the use of CAC scoring to optimize risk stratification and delivery of preventive therapies to individuals of SA ethnicity.
