We measured colloid osmotic pressure-pulmonary artery wedge pressure gradient (COP-PAWP gradient) and left ventricular stroke work index (LVSWI) before and after intraaortic balloon pumping (IABP). The following results are obtained.
1) The IABP is indicated in patients of LOS after cardiac surgery who have criteria 1. and 2.
1. COP-PAWP≤OmmHg
2. LVSWI≤25gm.m/m2
2) The change of COP-PAWP gradient is useful for prognostic indicator of IABP.
3) The reduction in COP-PAWP gradient may follow the onset of pulmonary edema.
