摘　　要：应用实时三维超声心动图评价冠心病患者经皮冠状动脉介入术(PCI)后左室收缩功能的变化。研究对象分为两组,正常组14例为冠脉造影无异常发现者,冠心病组49例行冠脉内支架治疗。所有患者均于术前及术后14天行实时三维超声检查,测得左室收缩末容积(LVESV)、左室舒张末容积(LVEDV)及左室射血分数(LVEF)。结果,正常组术前与术后LVESV、LVEDV及LVEF差异无统计学意义;冠心病组术后LVESV、LVEDV显著小于术前(P<0.001),LVEF显著高于术前(P<0.001)。结果表明,实时三维超声心动图能准确评价左室收缩功能,冠心病患者PCI后左室收缩功能明显改善。Objective To assess the effect on left ventricular systolic function after coronary artery intervention（PCI） using real-time three-dimensional echocardiography（RT-3DE）.Methods All sujects were divided into two groups： normal group consisted of fourteen normal subjects;and coronary heart disease group consisted of fourty-nine subjects performed by PCI.All subjects were examined by RT-3DE per-PCI and fourteen days after-PCI.The left ventricular end-systolic volume（LVESV）、 the left ventricular end-diastolic volume（LVEDV） and the left ventricular ejection fraction（LVEF） were measured.Results In normal group,there were no difference in LVESV、 LVEDV and LVEF between per-PCI and after-PCI;in coronary heart disease group,LVESV and LVEDV after-PCI were decreased significantly（P〈0.001）;and LVEF after-PCI were increased significantly（P〈0.001）.Conclusions RT-3DE is a useful modality to evaluate the left ventricular systolic function,PCI can improve the left ventricular systolic function in patients with coronary heart disease.
