摘要 目的了解扩张性心肌病(DCM)伴充血性心力衰竭(CHF)患者Tei指数的变化。方法用GE VVI 7彩色多普勒超声诊断仪测量患者接受心脏再同步化治疗(CRT)前后的Tei指数。结果42例患者治疗前Tei指数(0.65±0.14 Vs 0.32±0.08,P<0.01)和室内十二节段心肌运动达峰时间均差(87±21ms Vs 26±6.8ms,P<0.01)均明显高于对照组;CRT治疗可以明显改善Tei指数(0.65±0.14 Vs 0.41±0.11,P<0.01)和室内十二节段心肌运动达峰时间均差(87±21ms Vs 44±9.6ms,P<0.01)。结论Tei指数不仅可以反映DCM患者的心功能状态,还可用于CRT治疗疗效的监测。
