摘 要:目的评估心脏再同步化治疗(CRT)对心力衰竭(简称心衰)合并持续性心房颤动(简称房颤)患者的疗效。方法 12例慢性心衰的持续性房颤患者,心室率本身是慢的或经过药物治疗严格控制心室率,成功植入CRTD并打开心室感知反应及房颤传导反应功能。比较CRT-D植入术前和植入术后1年患者的总体幸福感量表(GWB)及心脏病症状评分(CSS),6 min步行试验,心功能分级以及超声心动图指标:左房内径(LAD)、左室舒张末期内径(LVDD),左室射血分数(LVEF),二尖瓣返流面积(MRA),心室间机械运动延迟(IVMD),左室12节段达峰时间标准差(12-Ts-SD)和左室12节段达峰时间最大差值(12-TP-MAX-D)。结果①12例随访1年内均无因心功能恶化再次入院,无死亡。②双室有效起搏比率达到93%±5%。③有3例在CRT-D植入后自行转复为窦性心律。④CRT-D植入后1年GWB、CSS,6 min步行试验,心功能分级较植入前均有明显改善[(70.25±16.61)vs(54.62±15.27),(16.67±5.23)vs(9.28±4.52),(320±65.24)m vs(214±43.74)m,2.43 vs 3.30,P均<0.05];CRT-D植入后1年,LAD缩小,LVEF升高,MRA减少[(40.2±10.6)mm vs(47.5±12.3)mm,(0.40±0.07)vs(0.28±0.05),(3.8±1.6)cm2vs(5.6±2.3)cm2,P均<0.05];IVMD、12-Ts-SD和12-TP-MAX-D得到改善[(35.4±17.8)ms vs(48.1±12.3)ms,(31.5±10.7)ms vs(44.5±15.2)ms,(100.6±22.9)ms vs(127.5±42.7)ms,P均<0.05]。结论慢心室率或经过药物治疗严格控制心室率的持续性房颤合并心衰患者能从CRT-D治疗中获益。Objective To observe and assess effect of cardiac resynchronization therapy(CRT) on patients with persis- tent atrial fibrillation(AF) and chronic heart failure (CHF). Methods Twelve patients with CHF and persistent AF, who had sufficient pharmacological rate control or initially slow ventricular rate ,underwent CRT-D implantation. CRT-D's ventricular sensation response and conducted AF response were opened. Quality of life (GWB and CSS) , New York Heart Association (NYHA) classification,6 min walk distance test (6MWDT) ,and echocardiographic parameters: left atrial di- ameter(LAD) ,left ventricular end diastolic diameter( LVDD), left ventricular ejection fraction( LVEF), intra- ventricular synchrony index( 12-TS-SD and 12-TP-MAX-D), interventricular mechanical delay(IVMD) were assessed before and after CRT-D with a follow-up of one year. Results ①All patient survived without hospitalization because of advanced heart failure at one year follow-up. ②Percentages of biventricular pacing was (93% ±5% ). ③Three patients spontaneously con- vetted persistent AF to sinus rhythm after CRT-D implantation. ④ CRT-D improved GWB and CSS, 6MWDT and NYHAfunctional class[ (70.25±16.61) vs (54.62±15.27), ( 16. 67±5.23 ) vs ( 9.28 ±4.52 ), ( 320±65.24 ) m vs ( 214_± 43.74)m,2.43 vs 3.30, all P〈0.053. LAD became smaller, LVEF increased, and MRA decreased after CRT- D[ (40.2±10.6)mm vs (47.5±12.3)mm,(0.40±0.07) vs (0.28±0.05),(3.8±1.6)cm2 vs (5.6±2.3)cm2, allP〈0.05]. IVMD reduced from (35.4±17.8)ms to (48. l±12.3)ms, 12-Ts-SD reduced from (31.5±10.7)ms to (44.5 ± 15.2 ) ms, and 12-TP-MAX-D reduced from ( 100.6±22.9 ) ms to ( 127.5 ±42.7 ) ms, respectively, all P〈O. 05 after CRT- D implantation. Conelttsions These suggested the beneficial effects of CRT-D implantation in the patients with CHF and persistent AF, who have sufficient pharmacological rate control or initially slow ve
