心脏再同步治疗(CRT)通过心脏同步性的改善,包括房室同步性、左心室内同步性和左、右心室间的同步性,改善左心室收缩功能,增加左心室充盈时间,减少二尖瓣反流,逆转慢性心脏重构,是近期慢性充血性心力衰竭(CHF)治疗的重大进展[1-2].现将我院30例已完成的CRT治疗患者的临床及随访资料进行分析,探讨CRT治疗CHF的疗效. 相似文献

Objective To investigate the effect of cardiac resynchronization therapy (CRT) and the problem of non-response to CRT in patients with chronic heart failure. Methods Twenty patients[(64±10.9) yrs,5 women, 15men] underwent CRT. Conventional echocardiography was performed in each patient before implantation and at 6 months post implantation. Results The clinical response rate was 60% and echocardio-graphic response rate was 55% at 6 month follow-up. Average EF increased 10%. Three patients died and 1 pa-tient was found to have increased left electrode thresholds. One electrode dislocation occurred and recannulation was required. Four patients had no response to CRT. The response rate to CRT was lower in patients with a nar-row QRS or ischemic cardiomyopathy. Conclusion CRT is an effective treatment for chronic heart failure pa-tients. Non-response to CRT may berelated to the cause of heart failure and narrow QRS. 相似文献

目的:探讨氟伐他汀联合普罗布考对急性冠脉综合征(ACS)患者血脂及血清超敏C-反应蛋白(hs-CRP)水平的影响。方法:收集ACS住院患者60例,随机分为A、B、C3组,每组20例,A组给予氟伐他汀40mg,1次/晚;B组给予氟伐他汀80mg,1次/晚;C组给予氟伐他汀40mg,1次/晚,并加用普罗布考250mg,2次/d。3组患者均于治疗前清晨空腹取血,测定hs-CRP和血脂水平,包括总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)。结果:治疗前3组间各项血脂指标及hs-CRP水平差异均无统计学意义(P0.05)。治疗后C组血脂指标和hs-CRP水平较A组均降低(P0.05),TC及HDL-C水平较B组均低(P0.05),而TG及LDL-C水平与B组比较差异无统计学意义(P0.05)。治疗后B、C组中TC、TG、LDL-C水平较治疗前降低(P0.05或P0.01);各组hs-CRP水平治疗前后差异均有统计意义(P0.05)。结论:氟伐他汀联合普罗布考或大剂量氟伐他汀均能明显降低ACS患者血脂及hs-CPR水平,尤以氟伐他汀联合普罗布考效果更为显著。 相似文献

冠状动脉(冠脉)在正常情况下走行于心外膜下的脂肪组织中或心外膜下,如果冠脉或其分支的某一段被心肌包绕,那么这段心肌被称为心肌桥(myocardial bridge,MB),造影显示在心脏收缩期,心肌收缩会导致冠脉狭窄,但是不会明显产生血流动力学变化,认为心肌桥只是一种良性的先天性冠脉畸形。随着近几十年来的医学技术的发展,对那些有症状的患者进行进一步检查,发现有些症状的罪魁祸首正是心肌桥的存在。本文就心肌桥的发病率、病理生理、临床表现、诊断和治疗做一综述。 相似文献

传统右室起搏为翼状电极右室心尖部起博(RVAP),与右室流出道起搏(RVOTP)相比,电极导管容易到达、方便圊定、不易脱位。近年来随着起搏器治疗适应证范围的不断扩大.大量高龄、严重心力衰竭和心脏明显扩大的患者入选本治疗方法,为了更好地固定电极防止其脱位,更大程度恢复心室生理激动顺序从而明显改善患者心功能,传统的起搏方式和电极导管已不能满足需要,螺旋电极的出现很好地解决了这一问题。近期我科选择80例双腔起搏治疗的患者为研究对象.探讨螺旋电极的安全性、可行性及优越性,现介绍如下。 相似文献
