摘　　要：目的:分析超声左心室压力-应变环参数水平与急性ST段抬高型心肌梗死(STEMI)患者介入治疗后左心室收缩功能的相关性。方法:回顾性分析2020年1月至2022年6月该院收治的53例STEMI患者的临床资料,作为观察组,另收集同期该院46名健康体检者的临床资料,作为对照组。两组均进行超声左心室压力-应变环检查。比较两组左心室收缩功能指标[左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、左心室射血分数(LVEF)]水平、超声左心室压力-应变环参数[整体做功指数(GWI)、整体有用功(GCW)、整体无用功(GWW)、整体做功效率(GWE)]水平,采用Pearson相关性分析超声左心室压力-应变环参数水平与STEMI患者介入治疗后左心室收缩功能的相关性。结果:观察组LVEDV、LVESV水平均高于对照组,LVEF水平低于对照组,差异有统计学意义(P<0.05);观察组GWI、GCW、GWE水平均低于对照组,GWW水平高于对照组,差异有统计学意义(P<0.05);Pearson相关性分析结果显示,GWI、GCW、GWE水平与LVEDV、LVESV水平均呈负相关(r<0,P<0.05),GWW水平与LVEDV、LVESV水平均呈正相关(r>0,P<0.05);GWI、GCW、GWE水平与LVEF水平均呈正相关(r>0,P<0.05),GWW水平与LVEF水平呈负相关(r<0,P<0.05)。结论:GWI、GCW、GWE水平与LVEDV、LVESV水平均呈负相关,GWW水平与LVEDV、LVESV水平均呈正相关;GWI、GCW、GWE水平与LVEF水平均呈正相关,GWW水平与LVEF水平呈负相关。Objective:To analyze correlations among left ventricular pressure-strain loop parameters and left ventricular systolic function in patients with acute ST-segment elevation myocardial infarction(STEMI)after interventional therapy.Methods:The clinical data of 53 patients with STEMI admitted to this hospital from January 2020 to June 2022 were retrospectively analyzed,and they were set as the observation group,and the clinical data of 46 healthy subjects during the same period were retrospectively analyzed,and they were set as the control group.Ultrasound left ventricular pressure-strain loop examination was performed in both groups.The levels of left ventricular systolic function indexes[left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular ejection fraction(LVEF)],left ventricular pressurestrain ring parameters[global work index(GWI),global useful work(GCW),global useless work(GWW),global work efficiency(GWE)]were compared between the two groups.Pearson correlation analysis was used to analyze the correlations among the left ventricular pressure-strain loop parameters and left ventricular systolic function in the STEMI patients after interventional therapy.Results:The levels of LVEDV and LVESV in the observation group were higher than those in the control group,the level of LVEF was lower than that in the control group,and the differences were statistically significant(P<0.05).The levels of GWI,GCW and GWE in the observation group were lower than those in the control group,the level of GWW was higher than that in the control group,and the differences were statistically significant(P<0.05).Pearson correlation analysis showed that the GWI,GCW and GWE levels were negatively correlated with the LVEDV and LVESV levels(r<0,P<0.05),the GWW level was positively correlated with the LVEDV and LVESV levels(r>0,P<0.05),the GWI,GCW and GWE levels were positively correlated with the LVEF level(r>0,P<0.05),and the GWW level was negatively correlated with the LVEF level(r<0,P<0.
