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。

Tissue mitral annular displacement in evaluating intraventricular synchronization in patients with chronic heart failure |
| |
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 QLAB81 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<005) 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. |
