Study on Coronary Artery Dimensions in Normal Adult Bangladeshis

Background: The heart is supplied by the two coronary arteries and their branches. Coronary computed tomography angiography is a cardiac imaging test that helps to determine coronary artery disease. The detailed anatomical knowledge of coronary arteries is essential for proper diagnosis and management of heart diseases. There is no published article available on morphometric analysis of normal coronary arteries by computed tomography angiogram in adult Bangladeshi people. Morphometry of the coronary arteries will provide useful baseline data to almost all the sectors of the medical science. Methods: A Cross-sectional, analytical study was conducted on 35 adult male and 35 adult female Bangladeshi people in Department of Anatomy, Dhaka Medical College, Dhaka, from January, 2017 to December, 2017. After obtaining the images of coronary CT angiogram, different dimensions of coronary arteries were measured by using a computer software program followed by statistical analysis. Results: The mean diameter of the left main coronary artery (LMCA) and left anterior descending artery (LAD), and the mean length of the right coronary artery (RCA), LMCA, and LAD were significantly higher in men than women (p < 0.05). However, there was no significant difference (p > 0.05) between men and women in the mean diameter of the RCA, or the mean diameter and mean length of the left circumflex artery (LCX). Conclusion: The study findings suggest that morphometric measurements of coronary arteries show variations among adult Bangladeshi male and female.
