Methods for the control of diabetes after acute myocardial infarction.
Blood glucose control in patients with diabetes after myocardial infarction is often poor, and this may contribute to increased mortality in the diabetic patient. A retrospective review of the records of 71 diabetic patients admitted with suspected myocardial infarction, and managed using a variety of methods, showed that adequate control (mean blood glucose less than 234 mg/dl; 13 mmol/L) was achieved in only 60%. Continuation of oral hypoglycemic agents and the use of irregular intermittent insulin in response to hyperglycemia were particularly associated with poor control. In a prospective study 68 consecutive patients were managed using regular subcutaneous insulin injections three times daily or a glucose-insulin-potassium intravenous infusion (in those with cardiogenic shock, severe hyperglycemia, or unable to eat). Control was adequate in 87% (P less than 0.001 versus retrospective group) and mean blood glucose concentration on days 1 and 2 were significantly lower than in the retrospective group (167 versus 232; 165 versus 236 mg/dl; both P less than 0.001). Simple protocols using three-times-daily subcutaneous insulin or glucose-insulin-potassium infusion provide a practical method for achieving good glycemic control in the diabetic patient with suspected acute myocardial infarction.
