Abstract

Background

There is no available data on normal coronary artery size in the Indian population. We attempted to establish a database for normal dimensions of the coronary artery segments during life by using quantitative coronary angiography and compared these with Western estimates of coronary artery size.

Material and Methods

Between december 2003 and June 2004, 94 patients who underwent quantitative coronary angiography for evaluation of symptoms of ischemic heart disease and were found to have no coronary artery disease form the sample size.

Results

The dimensions of branches in the left coronary system in our patients were less and those of the distal circumflex, and the proximal and distal left anterior descending coronary arteries were significantly greater than those of Indian Asians living in the United Kingdom and the native Caucasians but the dimensions of the right coronary artery were significantly greater in our patients.

Conclusions

Coronary artery dimensions for at least some branches of the left coronary system are similar to that reported in the West and the dimensions of the right coronary are greater. These findings contradict the general perception that Indians have smaller coronary arteries.
