Diabetic patients with acute myocardial infarction (MI) have particularly poor outcomes. Clinical practice guidelines from the American College of Cardiology/American Heart Association for the treatment of patients with acute coronary syndromes call for treatment to achieve preprandial glucose <110 mg/dL, a maximum daily target <180 mg/dL, and a post-discharge hemoglobin A1c <7%. Initiation of aggressive insulin therapy is also warranted to achieve blood glucose <150 mg/dL during days 0-3 and 80-110 mg/dL when possible thereafter. To date, no studies have been conducted assessing the efficacy of intravenous exenatide administration on achieving glucose lowering in hyperglycemic coronary ICU patients.
