摘　　要：目的:初步探讨实时三维超声心动图在冠心病左室节段心肌收缩功能中的应用价值。方法:对30例正常人与30例冠心病患者行三维超声心动图检查,采集心尖四腔动态三维超声心动图图像,并进行脱机分析,得出局部心肌射血分数(rEF),比较两组左室壁16节段射血分数及冠心患者在PCI治疗前后局部心肌射血分数。结果:冠心患者部分心肌局部射血分数比较与正常人相应部位心肌射血分数比较,差异有统计学意义(P<0.05),冠心患者介入治疗后局部心肌射血分数较治疗前有所提高,与治疗前比较,差异有统计学意义(P<0.05),与正常人局部心肌射血分数比较,差异无统计学意义(P>0.05)。结论:实时三维超声心动图可以定量评价冠心病左室节段心肌功能,帮助临床评价经皮冠状动脉介入(PCI)术后局部心肌功能恢复情况。Objective To explore the application value of left ventricular segmental myocardial systolic function in patients with coronary heart disease by real-time three-dimensional echocardiography.Method The study consisted of 30 normal subjects and 30 patients with coronary heart disease.Acquisition four-chamber apical dynamic three-dimensional echocardiography images and analysis off-line,the regional myocardial ejection fraction will be plotted.The 16 regional myocardial ejection fraction will be compared among normal subjects,coronary heart disease before PCI and after PCI.Results Compared with normal subjects,the regional myocardial ejection fraction in patient with coronary heart disease before treated by PCI was lower(P≤0.05).The patient with coronary heart disease after treated by PCI was higher than before(P≤0.05),and a little lower than normal subjects(P≥0.05).Conclusion Real-time three dimensional echocardiography can quantitative evaluate left ventricular segmental myocardial function in patients with coronary heart disease and observe the recovery of regional myocardial function after treated by PCI in clinical.
