摘要:

动态观察14例经皮冠状动脉腔内成形术(PTCA)病人手术前后心脏收缩时问间期(STI)变化，估价STI改变时判断晕厥心肌的价值。结果显示：PTCA后3～5 d，STI评价左心功能较为敏感的指标射血前时问／左室射血时间(PEP／LVET)比值。由0.386±0.600增加至0.460±0.070；至7～8 d恢复至术前水平。与同期测定的超声心动图左室射血分数(LVEF)相比，变化趋势一致。提示PTCA后，系列测定STI，可动态反映左心功能变化。PEP／LVET比值改变可作为判断晕厥心肌恢复的指标之一。

Abstract:

In order to evaluate the effects of the changes in systolic time intervals(STI)on the judgement of myocardium stunning，the authors compared variations in STI of 14 patients who had received percutaneous transluminal coronary angioplasty(PTCA)．The results showed that 3～5 d after the PTCA，the ratio of preejection period to the．1eft ventricular ejection time (PEP／LVET)rose from 0.386±0.070 to 0.460+±0.070；7～8 d after the PTCA，the PEP／LVET ratio(This ratio is a sensitive index of STI in evaluating the left cardiac function)became normal.The above results agree with the ejection fraction obtained by means of uhrasound cardiography suggesting that STI measured in series can show the changes in left cardiac function and that changes in the PEP／LVET ratio may serve、as one of the indexes for judgement of myocardlum stunning．
