摘要
目的:采用组织运动瓣环位移技术(TMAD)定量分析慢性心力衰竭(CHF)患者左室整体与节段纵向收缩功能,探讨其应用价值。方法:选择CHF患者22例,同期选择健康人20例作为对照组。采用QLAB8.1软件测量左心室整体与节段纵向应变(LSR),测量二尖瓣环6个位点(前间隔侧,后间隔侧,前壁侧,侧壁侧,后壁侧以及下壁侧)平均值,代表二尖瓣环整体位移(TMAD)。比较两组TMAD、LSR等参数,并分析LSR与TMAD的相关性。结果:与对照组比较,CHF组二尖瓣环6个位点TMAD以及TMADglobal均低于对照组(P<0.05);与对照组比较,CHF组各壁LSR以及GLS均低于对照组(P<0.05);两组|GLS|与TMADglobal分别呈线性正相关,两组|GLS|以及TMADglobal分别与LVEF呈线性正相关。结论:TMAD、LSR与LVEF具有相关性,是评价CHF患者左心室纵向整体与节段收缩功能的新方法。
Objective： To assess the left ventricular global and segmental longitudinal systolic function in patients with chronic heart failure （CHF） using tissue mitral annulus displacement （TMAD） quantitative analysis. Methods： There were 22 CHF patients and 20 healthy volunteers matched by gender and age. Left ventricular longitudinal strain （LSR） and the mitral annular displacement （six sites： anterioseptal, posterioseptal, anterior, lateral, posterior and inferior sites respectively ） were measured by the technique of 2D Strain Imaging （2D-SI） with QLABS. 1 software. The parameters of LSR and TMAD from two groups was compared, and the correlation between them was analyzed. Results： Compared with the control group, both TMAD of six spots and TMADglobal of CHF group were significantly decreased （ P 〈 0.05 ）, as well as LSR and GLS （ P 〈 0.05 ）. There were positive correlation between ｜ GLS｜ and TMADstobal, as well TMADglobal and ｜ GLS｜ with LVEF. Conclusion： TMAD and LSR are correlated with LVEF, which is a new method to assess left ventricular global and segmental longitudinal systolic function in patients with CHF.
