Glucose and insulin management in the post-MI setting

Abstract

Despite dramatic advances in the treatment of acute myocardial infarction (AMI) in recent years, patients with diabetes mellitus continue to experience disproportionately high morbidity and mortality. A substantial body of experimental and clinical data suggest that the ability of the heart to augment its energetic metabolism of glucose in the acute setting is critical to survival and functional recovery after AMI. Emerging evidence also suggests that chronic hyperglycemia may predispose to post-AMI ischemia and heart failure via adverse effects on coronary endothelial function and myocardial ultrastructure, energy metabolism, and gene transcription. A strong case can be made for intensive insulin-based control of glycemic level in the AMI patient with diabetes mellitus.
