COMPARATIVE STUDY OF CORONARY ANGIOGRAPHIC FINDINGS BETWEEN DIABETIC AND NON DIABETIC PATIENTS

Abstract

Background: Coronary artery disease (CAD) is one of the most important manifestation of diabetes mellitus. Objectives: To assess the extent of CAD in diabetic and non diabetic patients undergoing coronary angiography. Materials and Methods: 793 patients with suspected CAD, 202 diabetics and 591 non-diabetics were enrolled in the study. All patients underwent coronary angiography. Results: Normal coronaries were more common in non diabetic patients. Age at first presentation in diabetics was earlier as compared to non-diabetics. Diabetic female patients presented as early as third decade of life.  Single vessel involvement was significantly more in non diabetics [40.27%] as compared to diabetic patients[19.8%][P= <0.001], while there were statistically no significant differences in double vessel disease in both groups [P= 0.572]. Triple vessel disease were more common in diabetic than non diabetic patients [P= <0.001]. Left main disease, left circumflex coronary artery disease, coronary calcification, diffuse disease and CTOs were more common in diabetic patients. Conclusion: The severity and extent of CAD and incidence of triple vessel disease was significantly high in diabetics when compared to non diabetics.
