Primary objective of this study was to access utility of exercise treadmill test in type-2 diabetes mellitus patients for detecting silent myocardial ischaemia and associated risk factors. 75 DM-2 cases were enrolled in study of any age attending medical OPD. All cases were gone through detailed history and TMT procedure. There is higher prevalence of SMI in DM-2 patients. TMT positivity for inducible ischaemia in DM-2 patients were associated with increasing age, male sex, higher BMI, hypertension, smoking, alcoholism, microalbuminuria, macroalbuminuria and dyslipidemia. Duration of diabetes increases the development of CAD in diabetic patients. TMT is a safe procedure with no complication. For detection of silent myocardial ischaemia in diabetic patients TMT has a significant role. Prevalence of silent myocardial ischaemia in DM-2 patients is 37.3%. There is significant correlation between risk factors of CVD and evidence of ischaemia on TMT in diabetic patients. Duration of diabetic state has a strong correlation for inducible ischaemia on TMT. It may be a safer, cheaper, reliable and easily available non-invasive screening tool for earlier detection of CAD in diabetic patients.
