Abstract
Background & objectives: Diabetes mellitus, both insulin and non insulindependent, is an independent risk factor for coronary artery disease which have a larger infarct size, atypical ischemic symptoms and more post infarct complication than non diabetic patients.So the present study was undertaken with following objectives: (1) To study occurrences of various ischemic symptoms, complications and mortality between diabetics and non diabetics. (2) To find out the relation between duration of diabetes, glycemic control and mortality due to first episode of acute myocardial infarction. Methods: Total 100 cases of acute myocardial infarction included comprising 50 type 2 diabetic patients and 50 non diabetic patients. Patients having first episode of acute myocardial infarction and who is already known case of diabetes mellitus were included. Results: Highest incidence of first episode of acute myocardial infarction in diabetics was occurring at earlier age than non diabetics and more incidences in obese persons and diabetic females. There was less frequent occurrence of chest pain and perspiration in diabetics. Higher incidence of recurrent angina, bundle branch block, atrio-ventricular block and heart failure was noted in diabetics than non diabetics. 30 days mortality was higher in patients having Random blood sugar >198 gm% on admission and diabetes since more than 5 years. Interpretation & conclusion: In the present study, the overall conclusion has been made that in diabetic patients acute myocardial infarction occurs at earlier age, there are atypical ischemic symptoms and also higher incidence of complications and higher mortality rate. So in every patient of acute myocardial infarction glycaemia status should be assessed on admission and hyperglycaemia should be aggressively treated. [ Vegad A et al NJIRM 2012; 3(3) : 11-14]
