摘　　要：测量了冠状动脉狭窄前、后主动脉内气囊反搏（ＩＡＢＰ）时各项血流动力学参数的变化，分析和对比了左冠脉主干不同程度的狭窄对ＩＡＢＰ作用所产生的影响。结果表明：左冠状动脉主干中等程度狭窄时ＩＡＢＰ促进冠脉血液灌注的作用明显减弱。严重及非常严重狭窄时ＩＡＢＰ不能增进冠脉血供，仅能减少心脏后负荷。In order to improve perfusion of coronary artery in case of coronary artery stenosis, effect of intra-aortic ballon pumping (IABP) on coronary blood flow(CBF) was investigated.To this end hemodynamic parameters of heart functions with and withont stenosis were analysed under IABP.Hemodyriamic effect of IABP was obviously inflnenced by the coronary artery stenosis.
