摘　　要：目的探究实时三维超声心动图(RT-3DE)在急性心肌梗死(AMI)经皮冠状动脉介入术(PCI)后左心室容积及收缩功能评估中的应用价值。方法选取2022年1—6月景德镇市第二人民医院收治的30例AMI并行PCI的患者作为实验组,并根据年龄和性别匹配30例心血管系统无明显异常的患者作为对照组。所有患者均行常规二维超声心动图(2DE)及RT-3DE检查,比较实验组术前及术后1、3个月、对照组左心室收缩功能。以心脏磁共振成像(CMRI)为金标准,分析2DE、RT-3DE对AMI后左心室重构的诊断效能。结果术后1、3个月,实验组心室舒张末期容积(LVEDV)和左心室收缩末期容积(LVESV)均小于术前,左心室射血分数(LVEF)高于术前,且术后3个月LVEDV和LVESV均小于术后1个月,LVEF高于术后1个月,差异有统计学意义(P<0.05);术前及术后1、3个月,实验组LVEDV、LVESV均大于对照组,LVEF低于对照组,差异有统计学意义(P<0.05)。RT-3DE分析时间为(325.85±18.23)s,短于2DE的(428.95±26.68)s,差异有统计学意义(P<0.05)。以CMRI为检查的金标准,左心室重构19例,左心室正常构型11例。RT-3DE对左心室重构的诊断灵敏度、特异度、准确度均高于2DE,差异有统计学意义(P<0.05)。结论RT-3DE对AMI患者PCI后左心室容积及收缩功能的评估更为准确,分析时间更短,有助于疗效评估及随访,具有一定的临床价值。Objective To investigate the application value of real-time three-dimensional echocardiography(RT-3DE)in left ventricular volume and systolic function evaluation after percutaneous coronary intervention(PCI)in acute myocardial infarction(AMI).Methods 30 patients with AMI and PCI admitted to he Second People's Hospital of Jingdezhen from January 2022 to June 2022 were selected as the experimental group,and 30 patients with no obvious abnormality of cardiovascular system were matched according to age and sex as the control group.All patients underwent conventional two-dimensional echocardiography(2DE)and RT-3DE examination,the left ventricular systolic function of the experimental group before operation,1 month after operation,3 months after operation and the control group were compared.At the same time,cardiac magnetic resonance imaging(CMRI)was used as the gold standard to analyze the diagnostic efficacy of 2DE and RT-3DE in left ventricular remodeling after AMI.Results At 1 and 3 months after operation,the left ventricular end-diastolic volume(LVEDV)and left ventricular end-systolic volume(LVESV)in the experimental group were smaller than those before operation,the left ventricular ejection fraction(LVEF)was higher than that before operation,and the LVEDV and LVESV at 3 months after operation were smaller than those at 1 month after operation,and LVEF was higher than that at 1 month after operation,the differences were statistically significant(P<0.05);before operation and 1 and 3 months after operation,LVEDV and LVESV in the experimental group were higher than those in the control group,LVEF was lower than that in the control group,and the differences were statistically significant(P<0.05).The analysis time of RT-3DE was(325.85±18.23)s,which was shorter than(428.95±26.68)s of 2DE,and the difference was statistically significant(P<0.05).Using CMRI as the gold standard,19 cases of left ventricular remodeling and 11 cases of normal left ventricular configuration were found.The diagnostic sensitivity,specificity
