摘要
【目的】探讨急诊经皮冠状动脉介入治疗（PCI）对急性下壁心肌梗死患者右心功能的影响。【方法】在本院治疗的首次急性下壁心梗患者33例，其中17例12h内接受PCI治疗（观察组），16例择期接受PCI治疗（对照组）。两组患者分别于心梗后d1、d3、d7、d15、d30进行超声心动图检查，测量右房室环收缩期峰值运动速度（Sin）以及舒张早期峰值运动速度／心房收缩期峰值运动速度的比值（Em／Am），对右心室收缩和舒张功能进行评估。【结果】急性下壁心肌梗死后右室收缩功能和舒张功能分别于d1、d3最差，d30观察期结束时最佳。观察组Sm最小值和最大值以及Em／Am比值的最大值均高于对照组，且差异有显著性（P〈0．05）。观察组Sm值在d7显著增高，对照组则在d15显著增高（P〈0．05）；观察组Em／Am值在d15显著增高，对照组则在d30方显著增高（P〈0．05）。【结论】急诊PCI较择期PCI治疗有利于改善急性下壁心梗右室功能。
[Objective] To explore the effect of emergent percutaneous coronary intervention（PCI） on right ventricular function in patients with acute inferior myocardial infarction. [Methods] Totally 33 patients with acute inferior myocardial infarction admitted to our hospital for the first time were selected. Among them, 17 patients（observation group） received PCI treatment, and 16 patients（control group） received selective PCI. Echocardiography was performed for measuring systolic myocardial peak velocity of right atrioventricular ring （Sm） and the ratio of peak early diastolic movement velocity/atrial peak systolic velocity（Em/Am） in two groups were measured 1, 3, 7, 15 and 30d after myocardial infarction. Right ventricular systolic and diastolic function was evaluated. [Results] Right ventricular systolic and diastolic function were the worst on 1 and 3 days after acute inferior myocardial infarction and the best at the end of the observation period of 30 days. The maximum and minimum value of Sm and the maximum of Era/Am of observation group were significantly higher than those of control group, and there was significant difference（ P〈0.05）. Sm value of observation group significantly increased at d7 and that of control group significantly increased at d15 （ P〈0.05）. Era/Am of observation group significantly increased at d15 and that of control group significantly increased at d30 （ P〈0.05）. [Conclusion] Compared with elective PCI, emergency PCI is helpful for the improvement of right ventricular function in acute inferior wall myocardial infarction.
