摘　　要：目的:探讨慢性主动脉瓣反流患者应用超声心动图评价左心室几何构型改变的价值。方法:纳入2019年9月—2021年6月在无锡市人民医院门诊诊断的慢性主动脉瓣反流病患共计93例,其中轻度35例、中度31例、重度27例,分别设为轻度组、中度组、重度组;选取30名健康者作为对照组,所有研究对象均进行超声心动图检查,分析左室舒张末期长径和横径(Ld和Td)、收缩末期长径和横径(Ls和Ts);同时,计算左心室舒张末期和收缩末期的球形指数(Sid和Sis)。结果:中度和重度组左室长轴构型参数Ls、Ld、Td和Ts显著大于对照组,Sis和Sid显著小于对照组(P<0.05)。在左心室短轴构型参数方面,中度和重度组的APs、APd、LSs、LSd显著大于对照组(P<0.05)。轻度组左心室长轴和短轴构型参数与对照组之间均无显著差异(P>0.05)。结论:超声心动图能有效评价不同程度主动脉瓣反流患者的左心室几何构型改变,值得临床推广应用。Objective To investigate the value of echocardiography in evaluating left ventricular geometric configuration changes in patients with chronic aortic regurgitation.Methods A total of 93 patients with chronic aortic regurgitation who were diagnosed in the outpatient clinic of Wuxi People's Hospital from September 2019 to June 2021 were included,including 35 mild cases,31 moderate cases,and 27 severe cases,they were divided into mild group,moderate group and severe group;30 healthy people were selected as a control group.All the subjects underwent echocardiography to analyze the left ventricular end-diastolic long diameter and transverse diameter(Ld and Td),end-systolic long diameter and transverse diameter(Ls and Ts);at the same time,calculate the left ventricle spherical indices(Sid and Sis)at end-diastole and end-systole.Results The left ventricular long axis configuration parameters Ls,Ld,Td and Ts in the moderate and severe groups were significantly greater than those in the control group,the Sis and Sid were significantly lower than those in the control group(P<0.05).In terms of left ventricular short-axis configuration parameters,APs,APd,LSs,and LSd in the moderate and severe groups were significantly greater than those in the control group(P<0.05).The long axis and short axis configuration parameters of the left ventricle were not significantly different between the mild group and the control group(P>0.05).Conclusion Echocardiography can effectively evaluate the changes of left ventricular geometric configuration in patients with different degrees of aortic regurgitation,and it is worthy of clinical application.
