摘要
目的应用实时三维超声心动图(RT-3DE)评价择期经皮冠状动脉介入治疗术(PCI)对急性心肌梗死患者心室重构的影响。方法收集初次急性心肌梗死患者90例,根据治疗方法不同,分为择期PCI组(44例)和药物治疗组(46例)。于入院时和3个月时应用RT-3DE测量两组患者左心室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、射血分数(LVEF)。结果择期PCI组患者的LVEDV、LVESV各测值明显小于药物治疗组(P<0.01),而LVEF明显大于药物治疗组(P<0.01);LVEF的减小与LVEDV的增大呈负相关(r=-0.653)。结论择期PCI治疗能显著减轻急性心肌梗死患者的心室重构并改善患者的心脏功能。应用RT-3DE能够更清晰地显示心腔的立体结构,更好地测定LVEDV、LVESV。
Objective To evaluate the ventricular remodeling after selective percutaneous coronary intervention （PCI） for patients with acute myocardial infarction using real time three dimensional echocardiography （RT-3DE）.Methods Ninety patients with acute myocardial infarction for the first time were collected and divided into selective PCI group （44 cases） and conventional medical treatment group （46 cases）.The left ventricular end diastolic volume （LVEDV）,end systolic volume （LVESV） and ejection fraction （LVEF） were measured with real time three dimensional echocardiography on the admission to hospital and 3 months later.Results LVEDV and LVESV in the selective PCI groups were significantly less than those in the conventional medical treatment group （P0.01）,while LVEF in the selective PCI group was significantly higher （P0.01）.There was negative correlation between the decrease of LVEF and increase of LVEDV （r=-0.653）.Conclusion PCI can reduce ventricular remodeling and improve cardiac function.The application of RT-3DE can visualize clearer dynamic morphology views of heart,measure LVEDV and LVESV more accurately and correctly reflect the ventricular remodeling and cardiac function of the patients with acute myocardial infarction.
