摘　　要：目的探讨三维超声心动图自动定量(3DEA)技术对评估冠心病(CHD)患者经皮冠状动脉介入(PCI)术后左心室收缩功能的临床应用价值。方法选取50例行PCI的CHD患者,分别于术前及术后1个月、3个月行超声心动图检查,应用二维双平面Simpson's法(2DBP)及3DEA技术测量左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)及左心室射血分数(LVEF)。结果3DEA测量的LVEDV、LVESV及LVEF与2DBP法测值相关性高(r=0.92、0.90、0.84);与PCI术前相比,3DEA技术及2DBP法测量的PCI术后1个月、3个月LVEDV、LVESV均减低,LVEF均增加(P均<0.05),与PCI术后1个月比较,PCI术后3个月3DEA测量的LVEDV、LVESV减低,LVEF增加(P均<0.05),而2DBP测量的LVEDV、LVESV及LVEF差异均无统计学意义(P均>0.05)。与2DBP比较,3DEA技术分析时间短、重复性高(P均<0.05)。结论3DEA技术分析时间短、重复性高,与2DBP测值相关性高,能监测到PCI术后左心室容积及功能改善,对冠心病患者PCI术后疗效评估及长期随访具有临床应用价值。Objective To evaluate left ventricular systolic function in patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI)with three-dimensional echocardiographic automated algorithm(3DEA).Methods Fifty patients with CHD were enrolled.Left ventricular end-diastolic volume(LVEDV),end-systolic volume(LVESV)and ejection fraction(LVEF)were measured before PCI and 1 month and 3 months after PCI by using 3DEA and two-dimensional biplane Simpson's(2DBP)methods.Results LVEDV,LVESV and LVEF measured with 3DEA significantly correlated with those with 2DBP(r=0.92,0.90,0.84).Compared with measurements before PCI,LVEDV and LVESV measured with 3DEA and 2DBP methods decreased,while LVEF increased 1 month and 3 months after PCI(all P<0.05).Compared with one month after PCI,LVEDV,LVESV and LVEF measured with 3DEA further improved 3 months after PCI(all P<0.05),whereas LVEDV,LVESV and LVEF measured with 2DBP were not significantly different(all P>0.05).The time of 3DEA was short,and the reproducibility was higher than that of 2DBP(both P<0.05).Conclusion 3DEA method is rapid and highly reproducible and highly correlated with 2DBP,therefore may be a useful technique in serially following patients with CHD and assessing responses to PCI.
