    Abstract:
    BACKGROUND: In this study, we investigated whether adjunction of glucose-insulin-potassium (GIK) infusion to primary percutaneous coronary intervention (PCI) affects hemodynamics in patients with an acute myocardial infarction. METHODS: Hemodynamic measurements were performed in a subset of patients (n = 81) in the GIPS 2, starting immediately after PCI and continued for 12 hours. RESULTS: Cardiac index values were stable in both groups. During the first measurements, diastolic pulmonary artery pressure and the pulmonary capillary wedge pressure (PCWP) were significantly higher in the non-GIK group (diastolic pulmonary artery pressure 15 +/- 5 vs 18 +/- 7 mm Hg, P = .028 and PCWP 14 +/- 6 vs 18 +/- 7 mm Hg, P = .030). There was a decrease in PCWP from 18 +/- 7 to 15 +/- 6 mm Hg in the non-GIK group during the first 6 hours, whereas the pressures remained at 14 +/- 6 mm Hg in the GIK group. This difference in pattern of change did not reach statistical significance in the analysis of the interaction of PCWP by GIK group (P = .065). CONCLUSIONS: Glucose-insulin-potassium infusion as adjunctive therapy to PCI in patients with acute myocardial infarction, without overt signs of heart failure, did not negatively affect hemodynamics.
