Popis: WOS: 000234021900010 PubMed: 16310433 Percutaneous coronary intervention has been known to cause myocardial damage as a result of microvascular dysfunction due to microembolization and microinfarction. Previous studies have shown that glucose-insulin-potassium. (GIK) infusion decreases mortality in patients with acute myocardial infarction. Therefore, in this study, we aimed to investigate the effect of GIK infusion on myocardial damage due to percutaneous coronary revascularization. A total of 52 consecutive nondiabetic patients diagnosed with non-ST-elevation acute coronary syndrome and designated for elective percutaneous coronary intervention were randomized in a double-blind fashion into GIK and normal saline groups. GIK infusion (30% dextrose, 300 U insulin, and 60 mEq potassium chloride) at a dose of, 1.5 ml/kg/hour was initiated 24 hours before the intervention and continuing during and until 1 hour after the intervention. Troponin I levels were recorded in venous blood samples before and 12 and 24 hours after the intervention. The increase in troponin I was significantly lower at 12 and 24 hours in the GIK group compared with those of the saline controls (p = 0.022 and p = 0.005, respectively). GIK infusion initiated 24 hours before coronary stenting for non-ST-elevation acute coronary syndrome resulted in less myocardial damage as determined by postprocedure troponin I levels.
