摘　　要：目的探讨分层应变技术评估绝经期妇女左心室收缩功能的改变。方法连续性选择绝经期妇女41例以及年龄匹配的非绝经期妇女46例纳入研究。测量所有受试者左心室18节段整体平均纵向心内膜应变(Globle Longitudinal Strains of the Endocardium,GLS-endo)、中层心肌应变(Globle Longitudinal Strains of the Myocardium,GlS-myo)以及心外膜应变(Global Longitudinal Strain in the Epicardial Layer,GLS-epi)。结果两组左心室射血分数、左室舒张末期容积、左室收缩末期容积以及室间隔和左心室后壁厚度无统计学差异(P>0.05);两组分层应变均表现为从心内膜向心外膜逐渐递减趋势(P<0.001)。与绝经前组比较,绝经后组GlS-endo显著减低(P<0.001),两组GlS-myo和GlS-epi无统计学差异(P>0.05)。结论左心室分层应变的评估,为绝经期妇女心脏功能特定层的损害的认识提供了新的视角。Objective The aim of this study is to assess the functional change of the left ventricular longitudinal by using layerspecific strain in post-menopause women.Methods A total of 41 post-menopause women were included,and the control group included 46 age-matched pre-menopause women.The global of longitudinal strains of the endocardium(GLS-endo),myocardium(GLS-myo),and epicardium(GLS-epi)were obtained by averaging peak systolic strain of the left ventricle,with 18 segments in each layer.Results The left ventricular ejection fraction,left ventricular endsystolic volume,and left ventricular end-diastolic volume were similar between post-menopause women and pre-menopause women(P>0.05).Layer-specific strains showed a decreasing gradient from the endocardium to the epicardium in both groups(P<0.001)and were significantly different between post-menopause women and pre-menopause women in endocardium(P<0.05).Both GLS-myo and GLS-epi were no significantly different between post-menopause women and pre-menopause women(P>0.05).Conclusion Layer-specific evaluation of the left ventricle provides an understanding of the layer-specific properties of the left ventricle wall and the process of left ventricle impairment,and it may be helpful in managing post-menopause women.
