Objective: to investigate the relation between coronary stent restenosis and clinic factors.
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。
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.
在实施冠状动脉溶栓后，对于残留严重狭窄的病人经冠脉成形术可以达到比较理想的效果。
If the stenosis of infarct artery exists more than 90% after intracoronary thrombolysis, it is better to perform the PTCA as early as possible.
