Abstract
BACKGROUND: A number of factors may offset the cardioprotective effects of glucose-insulin-potassium (GIK) on outcome of patients with acute coronary syndrome, such as hyperglycemia induced by this cocktail infusion. We performed a study to evaluate the effect of intensive insulin therapy in association with GIK on 1-year outcome in patients hospitalized for acute coronary syndrome.
METHODS AND RESULTS: In a randomized prospective controlled trial we included 772 patients with non-ST-segment elevation acute coronary syndrome. Patients were randomized into 3 groups: GIKI2 group, who received GIK with intensive insulin therapy for 24 hours; GIK group, who received GIK with nonintensive insulin therapy; and control group, who received usual care. The primary outcome criteria were the rates of major cardiovascular events combining death, reinfarction, and stroke rate at 1 year. In addition, we measured platelet function assay-100 and plasminogen activator inhibitor-1 at admission and 24 hours later. Based on an intention-to-treat analysis, major cardiovascular events at 1 year was 12.8% in the GIKI2 group, 15.5% in the GIK group, and 20.5% in the placebo group; the difference was significant between the GIK2 and control groups (P=0.01). Platelet function assay-100 at 24 hours decreased significantly from baseline in the control group but not in the GIKI2 group. Plasminogen activator inhibitor-1 decreased significantly in the GIKI2 group but significantly increased in the control group. Minor hypoglycemic events were more frequent in the GIKI2 group compared with other groups.
CONCLUSIONS: GIKI2 led to improvement of 1-year outcome rates in patients with non-ST-segment elevation acute coronary syndrome. This beneficial effect was associated with a decrease in platelet reactivity and an increase on fibrinolysis tests.
