摘要 为评价常规超声和组织多普勒(TDI)超声指导下窄QRS间期合并心室不同步患者行心脏再同步治疗(CRT)对临床预后的影响,将91例经常规超声和TDI确定为心脏收缩不同步的慢性充血性心力衰竭患者分为CRT组43例(窄QRS间期组21例,宽QRS间期组22例)和对照组48例(窄QRS间期23例,宽QRS间期25例)。对所有患者进行1年的随访评价心功能及生存率。结果表明,与对照组相比,CRT组的6min步行试验变化、生活质量积分变化、NYHA分级改善明显增加。超声结果显示与对照组相比,CRT组左室收缩末期容量(LVESV)、左室舒张末期容量(LVEDV)明显减少,左室射血分数(LVEF)明显增加。与各对照组亚组相比,CRT-窄QRS亚组NYHA分级改善,6min步行距离变化、LVEF变化、生活质量积分变化明显增加。同时,LVESV和LVEDV明显减少。结论:应用超声多普勒指导的窄QRS间期患者也可以从CRT中获益。
