Abstract OBJECTIVE: To study the diameter of coronary arteries in a cohort of adult Pakistani population and to compare these with the diameters of Caucasians mentioned in the literature. METHODS: A study of 220 adult patients referred to National Institute of Cardiovascular Disease (NICVD) for diagnostic coronary angiography between May 2000 to December 2000. RESULTS: The mean diameter of Right Coronary Artery (RCA) was found to be 3.08 + 0.78 mm with a 95\% CI of 2.9 - 3.2, and of Left Main Coronary Artery (LMCA), 4.28 +/- 0.82 with a 95\% CI of 4.2 - 4.4. While the mean diameter of Left Anterior Descending Artery (LAD) was 3.22 +/- 0.74 with a 95\% CI of 3.1 - 3.33, and that of the Circumflex Artery (CX) 3.02 + 0.75 with a 95\% CI 2.9 - 3.1. The total coronary area (TCA), diameter of three vessels was 9.32 + 1.68 with a 95\% CI of 9.1 - 9.5, while the sum of 4 vessels diameter was 13.6 + 2.26 with a 95\% CI of 13.3 - 13.9. CONCLUSION: The diameters of coronary arteries of Pakistani population are not significantly different from that of Caucasians and the cause of increased mortality in the people of South Asians origin seems to be other than the diameter of coronary arteries.
