Abstract
IntroductionThe prevalence of coronary artery disease is comparatively higher in males than females. The present research studies the sexual dimorphism in the luminal diameter of the left anterior descending artery. MethodsThe study was conducted on 35 male and 35 female cadaver hearts. This histomorphometric study was performed by using the computer assisted microscope, to understand the gender based variation in the arterial lumen. ResultsThe study observed that the luminal diameter of the left anterior descending artery was higher in males. However, on correction with the weight of the heart, females showed a significantly wider coronary artery lumen, possibly indicating a better coronary flow in female hearts. DiscussionThe study observation suggests how the females are better protected from the coronary artery disease than the males. More elaborate studies on larger sample are suggested to confirm the observations of the present study.
