| Summary: | Coronary artery disease (CAD) is a major determinant of the long-term prognosis among patients with diabetes mellitus (DM). DM is associated with a 2 to 4-fold increased mortality risk from heart disease. Furthermore, in patients with DM there is an increased mortality after MI, and worse overall prognosis with CAD. Near-normal glycemic control for a median of 3.5 to 5 years does not reduce cardiovascular events. Thus, the general goal of HbA1c <7% appears reasonable for the majority of patients. Iatrogenic hypoglycemia is the limiting factor in the glycemic management of diabetes, and is an independent cause of excess morbidity and mortality. Statins are effective in reducing major coronary events, stroke, and the need for coronary revascularization.
