Coronary arteries were studied on 110 postmortem human hearts during January 2000 to December 2001 in the department of Anatomy and Microbiology, Bangladesh Medical College. Hearts were collected from mortuary of Dhaka Medical College. These were the hearts of deceased persons suspected of abnormal deaths. Atherosclerosis was found in 49(44.5%) samples, among which 37 (5.%) were from male and 12(26.7%) from female hearts. This difference was significant (P<0.01). Atherosclerosis was present in 11(10.0%), 22(20.0%) and 16(14.5%) samples on right coronary artery, anterior descending and circumflex branch of left coronary artery irrespective of sex.
