Abstract

Background: Diabetes is the commonest endocrine disease affecting mankind. The present study was conducted to assess ECG abnormalities and treadmill test findings in patients with type 2 diabetes mellitus.
Materials & Methods: 80 diabetic and 50 non-diabetic subjects of both genders were enrolled. All the subjects underwent fasting and postprandial blood sugar, glycosylated haemoglobin (HbA1c), lipid profile (fasting and post-prandial), electrocardiography (ECG), and treadmill test (TMT) monitoring.
Results: Group I had 50 males and 30 females and group II had 20 males and 30 females. Out of 80 diabetes patients, ST depression & T wave inversion was found in 24, 10 had  Left atrial enlargement(LAE), 6 had left ventricular hypertrophy(LVH), 4 had Right bundle branch block (RBBB) and 2 had left bundle branch block (LBBB). The difference was significant (P< 0.05). 52% had abnormal triglyceride (TG), 54% abnormal total cholesterol(TC), 55% abnormal high-density lipids (HDL), and 56% abnormal low-density lipids (LDL) having positive TMT test. The difference was significant (P< 0.05).
Conclusion: Patients with T2DM had a higher prevalence of ECG abnormality. T2DM patients are also found to be more TMT-positive.
