STRESS HYPERGLYCEMIA IN ACUTE MYOCARDIAL INFARCTION AND RELATION WITH ACUTE INTRAHOSPITAL COMPLICATIONS

Background : Myocardial infarction is the most important cause of mortality all over the world. Complications may increase with some risk factors including stress hyperglycemia. The aim of this study was to evaluate the correlation and importance of hyperglycemia in acute intrahospital complications after AMI. Methods : Prevalence of stress hyperglycemia among 160 patients with acute myocardial infarction (Q wave MI) was determined. These patients were divided into normoglycemic and stress hyperglycemic groups. These were compared according to complications such as heart failure, cardiogenic shock and mortality. Results : 61% were normoglycemic and 7.5% had stress hyperglycemia. 25% had history of diabetes and 4.4% were not aware of diabetes. Among 18 patients with stress hyperglycemia, 6 patient (50%) and among 101 normoglycemic patients 18 (17.8%) were affiliated with cardiac failure that the difference were significant (P=0.02 and χ 2= 6.25). There were no cases of cardiogenic shock in both groups. Three patients died during first hours of admission (2.97%). They hadn't have history of diabetes. We could not assign them to normoglycemic or stress hyperglycemic groups since blood sampling had not been done yet.  Conclusion : Stress hyperglycemia can increase complications of AMI, significantly stress hyperglycemia caused increased incidence of heart failure in this study
