Carbohydrate Tolerance Status in Patients with Myocardial Infarction
2014
Hyperglycemia is an important independent risk factor in the development of coronary artery disease. Sixty one patients suffering from chronic and acute myocardial infarction out of which 12 patients were diabetic and 10 normal control subjects were investigated. The patients without diabetes and control subjects were subjected to oral and intravenous glucose tolerance tests. It was observed that the post load glucose level of most of the patients and fasting insulin level of patients without diabetes were higher as compared with control subjects. From the intravenous glucose tolerance test, half life of glucose and glucose assimilation coefficient were determined. Half life of glucose was increased significantly and glucose assimilation coefficient was decreased in the patients with myocardial infarction as compared with those of control subjects. The observations confirm that carbohydrate intolerance in myocardial infarction is not due to suppression of insulin secretion but due to peripheral utilization.
