Study to Determine the Diagnostic Utility of Treadmill Test in Asymptomatic Coronary Artery Disease Patients with Type 2 Diabetes Mellitus

ABSTRACT

Background:Coronary Artery Disease being the leading cause of death in patients with Type 2 Diabetes Mellitus often may remain asymptomatic due to silent Myocardial ischemia. People suffering from diabetes mellitus have 2-4 times higher risk of developing coronary artery disease. In such patients periodical clinical examinations and resting ECG may not detect the impending coronary artery disease. Therefore, we analysed the diagnostic utility of Treadmill Test in predicting Silent cases of Myocardial Ischemia. Methods: Our study was conducted as an Observational study over a period of 1.5 years including 50 patients of Type 2 Diabetes Mellitus. This study was conducted at a tertiary care centre of Western Uttar Pradesh. Results: The results of Treadmill test demonstrated that amongst the studied cases of Type 2 diabetes mellitusapproximately one-third of the cases showed positive association whereas the rest were negative. These positive TMT cases were associated with longer duration of Type 2 Diabetes Mellitus. In this study we also evaluated possible association between Autonomic Dysfunction with Positive Treadmill Test. Conclusion: Our study concluded that Screening for Coronary Artery Disease should be done in all Type 2 Diabetes Mellitus patients with prolong duration of Diabetes and with Autonomic Neuropathy. As it will lead to early detection of Coronary Artery Disease and its management will reduce the morbidity and mortality due to the same.
