Correlation of Atherosclerotic and Thrombotic Coronary Artery Disease with Anatomical Distribution

Abstract

Atherosclerosis is a slowly progressive disease of arteries marked by elevated fibro fatty intimal plaque involving large to medium sized muscular arteries like coronary arteries. Atherosclerotic changes occur not in a uniform pattern. It tends to occur in certain predisposed regions. The distribution of coronary artery in the coronary artery and its branches are studied in dead bodies brought for post mortem examination.The incidence of atherosclerotic change in relation to the branches of coronary arteries is studied.The incidence of atherosclerosis was found to be more at the branching site of the coronary arteries. It was maximum at the site of division of the left main coronary into anterior descending (ADB) and circumflex (LCx) branches. The branching site (BS) and its proximal part also showed equal incidence. Right coronary (RCA) showed maximum incidence at the branching site (BS). The proximal part of right coronary showed relatively lower incidence.
