目的 观察心脏再同步化治疗对窄QRS波群慢性心力衰竭患者的临床疗效. 方法 对5例QRS时间<120ms的慢性心力衰竭患者行双心室再同步起搏治疗.术后随访(15.6±12.1)个月,观察心功能、活动耐量、夜间心率、心率变异性(SDNN)和左心室射血分数;组织多普勒检测左心室内各心室壁收缩期达峰时间标准差(Ts-SD);三维超声心动描记术检测左心室16、12、6节段达最小容积点时间的标准差(Tmsv-Dis)和最大时间差(Tmsv-Dif). 结果 治疗后心功能NYHA分级从Ⅲ、Ⅳ级改善为Ⅱ、Ⅲ级,活动度从(0.03±0.05)h/d增加至(2.93±1.10)h/d,夜间心率由(85.0±3.6)次/min降低至(62.3±2.5)次/min,SDNN从(48.3±7.6)ms升至(116.7±5.8)ms,左心室射血分数从(21.2±4.5)%提高至(34.7±5.1)%(P<0.05). Ts-SD,Tmsv-Dis及Tmsv-Dif均有明显减低(P<0.05). 结论 窄QRS波群慢性心力衰竭患者可接受心脏再同步化治疗,术前应用超声心动描记术及组织多普勒等评价患者心室运动的失同步是很必要的.     

慢性心力衰竭患者心脏再同步治疗疗效观察

目的随访慢性心力衰竭患者心脏再同步治疗（CRT）的临床疗效。方法入选1999年至2008年行CRT的慢性心力衰竭患者,收集这些患者基线和最后一次临床资料。采集数据包括临床心功能评估,心脏超声学指标和体表心电图QRS时限宽度。结果95例患者行CRT治疗,分为早期组和近期组。早期组随访时间（57±17）个月,随访生存率为66．6％;近期组随访时间（18±10）个月,生存率为89．1％。两组患者CRT治疗后心功能显著提高,但自身状态下体表心电图QRS时限宽度变化差异无统计学意义。随访中患者药物治疗变化明显。结论中长期和短期随访均证实CRT治疗在一部分慢性心力衰竭患者中能提高心功能,但缺乏预测疗效的敏感指标。

慢性心力衰竭患者心脏再同步治疗疗效观察

Objective This study was designed to evaluate the clinical outcome of cardiac resynchro-nization therapy(CRT) during short and mid-long term follow-up. Methods Consecutive patients treated with CRT between 1999 and 2008 were registered. Clinical information was collected from baseline and last follow-up. Clinical information included survival, chnical cardiac function, echocardiography parameters and QRS wave width from surface ECG. Results Ninety-five patients who were treated with CRT successfully were included. These patients were divided into two groups: those with only short term follow-up and those with mid-long term follow-up. In the short term follow-up group,survival was 89.1% with follow-up of(18±10) month(median = 18 months). Survival was 66.6% in mid-long term group with follow-up of(57±17) months (median = 54 moths). While clinical cardiac function was significantly improved in both groups the intrinsic QRS wave width did not show significant change. Those patients' medical therapy for chronic heart failure has been changed dur-ing the period of follow-up. Conclusion CRT can improve clinical cardiac function in parts of patients with chronic heart failure and increased survival during mid-long term and short term follow-up. However, there re-mains a need for more sensitive indicators.

慢性心力衰竭患者行心脏再同步化治疗的护理

慢性心力衰竭（chronic heart failure，CHF）是一种心室功能障碍和神经内分泌调节异常导致的肺静脉充血、运动耐力和生存期降低的临床综合征，是近年来发病率和流行性很高的心血管病症。     

心脏再同步化治疗心力衰竭的研究进展

药物能有效改善心力衰竭患者的症状,但是对于心功能Ⅲ-Ⅳ级的严重心力衰竭患者,心脏再同步化治疗是唯一能显著改善预后的有力治疗方法。本文从心脏再同步化治疗心力衰竭适应证的拓展、QRS时限与形态在CRT治疗中的重要地位、心脏再同步化治疗的优化程控与CRT治疗机制、CRT起搏电极植入技术及电极位置对应答效果的影响、CRT应答的预测因子评价与治疗展望五个方面对心脏再同步化治疗心力衰竭的研究进展进行综述。     

组织多普勒超声评价窄QRS间期患者心脏再同步治疗效果

目的组织多普勒超声（TDI）指导下评价窄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。方法91例经超声心动图和TD[确诊为心脏收缩不同步的慢件心力衰竭患者,按是否接受CRT分为CRT组（窄QRS间期21例,宽QRS间期22例）和对照组（宽QRS间期25例,窄QRS间期23例）。对所有患者进行1年的随访,评价心功能及生存率。结果CRT组6min步行试验、生活质量积分、心功能（NYHA分级）明显改善。超声心动图及TDI结果显示,CRT组左心室收缩未容积、左心室舒张末容积明显减少,射血分数明显增加。与各对照组亚组相比,CRT组中窄QRS亚组心功能改善,6min步行试验距离、左心室射血分数、生活质量积分明垃增加,左心室收缩末容积和左心窀舒张末容积明显减少。结论在TDI指导下,窄QRS间期慢性心力衰竭可以从CRT中获益。     

心脏再同步治疗慢性心力衰竭患者细胞因子浓度变化及其与左室射血分数的关系

目的探讨心脏再同步治疗（CRT）1个月、3个月对慢性心力衰竭患者血清细胞因子水平的影响及其与左室射血分数（LVEF）的关系。方法入选心功能Ⅲ～Ⅳ级的患者30例,分为CRT组15例,对照组15例。两组于治疗前、治疗后1个月及3个月分别测定肿瘤坏死因子-α（TNF-α）和白细胞介素-6（IL-6）浓度,超声测量LVEF。结果CRT组治疗3个月后TNF-α、IL-6浓度与治疗前相比明显下降。治疗后1个月及3个月,CRT组LVEF均较治疗前明显改善。细胞因子（TNF-α、IL-6）浓度与LVEF呈显著负相关。结论CRT治疗3个月后心功能改善的同时细胞因子浓度降低,提示血清TNF-α、IL-6浓度可作为慢性心力衰竭患者心功能的预测指标。
