Abstract
Aims: The primary objective of this study was to evaluate the normal coronary artery dimensions in the Indian population using quantitative coronary angiography with an aim to determine whether the increased risk of coronary artery diseases in Indians, diabetics in particular is due to narrower coronary arteries as widely believed.
Methods: A total of 321 patients who underwent coronary angiography for the evaluation of their symptoms and were found to have normal epicardial coronary arteries were included in the study. Written Informed consent was obtained from each patient and the study was conducted according to the applicable guidelines for good clinical practice (GCP). Standard angiographic views were obtained and quantitative coronary Angiography was carried out on longest possible disease-free segments of coronary arteries. The vessels were assessed in an end diastolic frame.
Results: There were 165 men and 156 women with a mean age of 49.9 years (±11.22). The mean body surface area among males was significantly higher than females (p value <0.001). The mean coronary artery diameter was higher in males as compared to females and the difference was statistically significant except for diagonal branch of left anterior descending artery, distal right coronary artery and posterior descending artery. The mean coronary artery diameter in diabetic was lower than the non-diabetic patients but the difference was not statistically significant.
Conclusion: Our study contradicts the general belief that Indians have narrower coronary arteries than their western counterpart.

Keywords: Coronary artery dimensions, Indian population, Normal coronary artery
