A Cross Sectional Study among Type 2 Diabetes Cases with Silent Myocardial Ischaemia in a Tertiary Care Center in a Northern Maharahstra

Abstract

Introduction: Silent myocardial ischemia is defined as objective evidence of myocardial ischemia without angina or angina equivalent. In Framingham study, 30% of myocardial infarcts were silent, diagnosed only by serial electrocardiography. There is increasing evidence that asymptomatic myocardial infarctions and silent ischemia occur more frequently in diabetic patients. So present study was done to record the prevalence of silent myocardial ischemia in asymptomatic patients of type 2 diabetes mellitus. Material and methods: The present study was a cross sectional study, carried out among 88 randomly selected patients of type 2 diabetes mellitus for more than 1 year, patients >18 years of age, who do not have any symptoms related to cardiovascular system. Results: Our study shows that the prevalence of silent MI among patients with DM was 20.45%. It was reported in the present study that the mean fasting and post prandial blood sugar among patients was 162.23±12.18 mg/dl and 192.4±21.29 mg/dl respectively. Conclusion: Our study shows that the prevalence of silent MI among patients with DM was 20.45%. In our study majority of cases of silent myocardial ischemia were found in patients with age group of >50 years, patients with duration of diabetes mellitus of 5-10 years.
