在急性心肌梗塞并发心源性休克用主动脉内气囊反搏术(IABP)治疗15个病人,我们评价其血液动力学和左室功能的改善情况。以右心室导管直接测定和放射核素照影进行研究。IABP 可减低左室舒张末期容积平均从134ml 降到114ml 和左室收缩末期容积平均从100ml 降到72ml。左室每搏驱缸量从34ml 升到42ml,每分搏出量从3.0升高到3.6L/min,左室射血分值从27.6％升为36.1％。肺毛细血管嵌顿压平均从15mmHg 降
In 15 patients with acute myocardial infarction complicated with cardiogenic shock treated with intra-aortic balloon catheterization (IABP), we assessed their hemodynamic and left ventricular function improvement. Right ventricular catheterization and radionuclide direct imaging studies. IABP reduced left ventricular end-diastolic volume averaged from 134ml to 114ml and end-systolic volume averaged from 100ml to 72ml. Left ventricular stroke volume per cylinder from 34ml rose 42ml, per minute volume increased from 3.0 to 3.6L / min, left ventricular ejection fraction rose from 27.6% to 36.1%. Pulmonary capillary incarceration pressure dropped averagely from 15 mmHg
