摘要:
目的:探讨组织运动瓣环位移技术（TMAD）定量分析慢性心力衰竭（CHF）患者左室内收缩运动同步性的价值。方法:选择CHF患者33例，同期选择健康人25例作为对照组。采用QLAB8.1软件测量左心室16节段收缩末期容积达峰时间标准差（Tmsv16-SD）以及测量二尖瓣环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) 二尖瓣环位移达峰时间，计算其标准差(TP-SD)。比较两组Tmsv16-SD、TP-SD等参数，并分析Tmsv16-SD与TP-SD的相关性。结果:与对照组比较，CHF组Tmsv16-SD及TP-SD均高于对照组（P<0.05）；Tmsv16-SD与TP-SD呈线性正相关。结论:组织运动瓣环位移技术是评价CHF患者左室内运动同步性的新方法。
Abstract:
AIM:To explore the value of tissue mitral annular displacement (TMAD) in assessment of left ventricular synchronization in patients with chronic heart failure (CHF). METHODS: Thirtythree patients with CHF and 25 healthy volunteers were enrolled in this study. Tmsv16SD of left ventricle and the time of mitral annular displacement to peak were measured using the QLAB81 software at six sites (anteroseptal, posteroseptal, anterior, lateral, posterior and inferior). Standard deviation of the time to peak was calculated. Tmsv16SD and TPSD of the two groups were compared and the correlation between Tmsv16SD and TPSD was analyzed. RESULTS: Compared with those in control group, TPSD and Tmsv16SD in CHF group significantly increased (P<005) and Tmsv16SD and TPSD was positively correlated. CONCLUSION: TMAD is a new method for the assessment of left ventricular synchronization in patients with CHF.
