Materials & Methods
: 30 hearts were collected from the cadavers .They were carefully dissected and examined for the type of pattern of coronary vasculature. A dye was also injected for visualization of the coronary blood vessels and observed that how many hearts are of right predominance and how many are of left predominance. Like wise 460 coronary angiograms were also studied and noted the fact that how many hearts belongs to "Right predominance and how many hearts are of "left predominance".

Summary& results: The study with 30 cadaver hearts revealed that 90% of hearts are of right coronary predominance and 10% of them showed left predominance. From 460 angiograms of the live hearts of the patients attending the hospitals showed 85% ( 391) of right coronary artery predominance while 15% (69) of left coronary artery predominance. Among the smokers, 37% had Single vessel disease (SVD), 29% had Double vessel disease (DVD),24% had Triple vessel disease (TVD) and 10% of them had no significant cardiac disease. Among the hypertensive patients had 38% SVD, 29% DVD, 22% TVD and 11% had no significant cardiac disease. Among the diabetic patients had 38% SVD, 28% DVD, 25% TVD and 9% had no significant cardiac disease.

: The right coronary artery is the predominant artery in most cases according to this study.
