摘要 目的应用左室压力-应变环(PSL)定量评价非ST段抬高型心肌梗死(NSTEMI)患者的心肌做功参数的变化。方法选取就诊的非ST段抬高型心肌梗死患者30例,同时选取同期健康体检者30例作为对照组,应用PSL技术定量评估左室心肌功能,并获取心肌做功参数:GWI、GCW、GWW、GWE、LVEF及GLS,比较病例组与对照组之间的心肌做功的差异,并将左室心肌做功参数与LVEF、GLS做相关性分析。结果相对于对照组,病例组的GWI、GCW、GWE降低,GWW升高,差异均有统计学意义(P<0.05)。GWI、GCW、GWW、GWE与LVEF、GLS均显著相关(P<0.001)。结论左室PSL可定量评估NSTEMI患者的心肌做功,为评价左心室收缩功能提供一种新方法。 Objective To quantitatively evaluate the changes of myocardial work parameters by left ventricular pressure-strain loops(PSL) using echocardiography in patients with non-ST-segment elevation myocardial infarction(NSTEMI). Methods A total of 30 patients with suspected NSTEMI who were admitted to the Second Affiliated Hospital of Harbin Medical University fromand 30 healthy people were selected as the control group. The left ventricular myocardial function was quantitatively evaluated by PSL and cardiac work parameters were obtained, including GWI,GCW,GWW,GWE,LVEF and GLS. To compare the difference of myocardial work between control group and case group. And the correlation analysis of left ventricular myocardial work parameters with LVEF and GLS was conducted. Results Compared with the control group, GWI, GCW and GWE in case group decreased, and GWW increased significantly(P<0.05). GWI, GCW, GWW, GWE were significantly correlated with LVEF and GLS(P<0.001). Conclusions Left ventricular PSL can quantitatively assess the myocardial work of patients with NSTEMI and provide a new method for quantitative assessment of left ventricular systolic function.
