Coronary artery disease (CAD) is more common in diabetics and is the leading cause of death in patients with type 2 diabetes and is often asymptomatic because of silent myocardial ischemia. It has been recognized for several decades that diabetes mellitus is an established risk factor for cardiovascular morbidity and mortality. About three-quarters of the cardiovascular deaths from diabetes result from coronary artery disease. Coronary artery disease is multifactorial in etiology and has several important risk factors, out of which diabetes is one of the important modifiable risk factor. The patients of type 2 diabetes mellitus without clinical evidence of coronary artery disease attending diabetic clinic, cardiology and medicine OPD, at medical college and hospital were enrolled in the present study. In the present study out of 102 patients, TMT was positive in 32 (31.37%) and negative in 70 (68.63%) patients. TMT was positive in 13/61 (21.31%), 9/27 (33.33%), 7/10 (70%) and 3/4 (75%) patients with duration of diabetes >5, 6 to 10, 1 1 to 15 and 16 to 20 years respectively.
