Coronary artery dimensions in Indians are similar to Western populations when indexed to body surface area. However, Indians generally have smaller coronary arteries due to a smaller body habitus.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Imaging
Background:
- Coronary artery diameter is crucial for predicting outcomes of cardiac interventions.
- Limited data exists on coronary artery dimensions specifically within the Indian population.
Purpose of the Study:
- To determine normal coronary artery dimensions in Indian adults without coronary artery disease.
- To compare these dimensions with those of Western populations.
Main Methods:
- Quantitative coronary angiography was performed on 229 Indian patients with normal coronary angiograms.
- Coronary artery diameters were measured and analyzed.
Main Results:
- The left main coronary artery was the largest, followed by proximal LAD, proximal RCA, and proximal LCX.
- No significant gender-based differences in coronary artery diameter were observed when indexed to body surface area.
- While unadjusted, Indian coronary arteries were smaller than Caucasians, indexing to body surface area revealed no significant difference.
Conclusions:
- Coronary artery size, when indexed to body surface area, shows no statistical difference between Indian males and females.
- Indexed coronary artery dimensions in Indians are comparable to those in Caucasians.
- Indians possess smaller coronary arteries overall, correlating with their smaller average body habitus.

Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
