摘    要:目的观察心脏再同步治疗慢性心力衰竭的临床疗效。方法36例慢性心力衰竭合并室内传导阻滞的患者行双心室再同步起搏治疗。全部患者均经冠状静脉窦植入左心室导线至心脏静脉。治疗后随访12个月,观察心功能,6min步行距离,QRS波宽度,心室间运动延迟,左心室收缩、舒张末内径,左心室射血分数,二尖瓣反流面积。结果31例治疗后心功能改善,有效率86.1%(31/36)。心功能从Ⅲ~Ⅳ级(纽约心脏协会心功能分级)改善为Ⅱ~Ⅲ级;6min步行距离从(362±153)m提高至(528_+165)m,差异有统计学意义(P〈0.01);QRS波从(164.74±33.76)ms缩短至(129.45±42.27)ms,差异有统计学意义(P〈0.01);心室间运动延迟时间从(65.19±21.50)ms缩短至(33.25±13.62)ms,差异有统计学意义(P〈0.01);左心室舒张末内径从(66.52±10.23)mm缩小至(60.63±9.97)mm(P〈0.05),左心室收缩末内径从(55.73±10.62)mm缩小至(47.45±11.35)mm,差异有统计学意义(P〈0.01);左心室射血分数从30.35%±4.69%提高至42.27%±8.40%,差异有统计学意义(P〈0.01);二尖瓣反流面积从(7.52±3.62)cm2减少至(4.33±2.07)cm2,差异有统计学意义(P〈0.01)。结论心脏再同步治疗是治疗慢性心力衰竭的有效方法,能使心脏活动再同步化,改善心功能。

Abstract:Objectives To observe the clinical effect of cardiac resynchronization therapy in patients with chronic heart failure.Methods Thirty-six patients with chronic heart failure and left bundle branch block received biventricular resynchronous pacing,and left ventricle leads were implanted into one of cardiac veins.During the 12-month follow-up,cardiac function,6-minute walk distance,QRS width,inter-ventricular movement delay,left ventricular end-diastolic diameter,left ventricular ejection function and mitral r...
Keywords:chronic heart failure  cardiac resynchronization therapy  heart conduction block
