Asian-Indians have high rates of coronary artery disease (CAD), which also occurs at an earlier age, with 50% of all heart attacks occurring in patients <55 years old and 25% in those <40 years old. Previous studies have cited structural factors in Asian-Indians, specifically smaller coronary arteries, as the cause of increased CAD in this population. We found that Asian-Indian patients have smaller coronary arteries, with a statistically significant difference in the mean diameter even after correction for body surface area.
