人工心脏起搏器对高龄患者生活质量及预后的影响

Effect of pacemakers on the quality of life and clinical outcomes in elderly patients

目的:对比安装单心室或双腔心脏起搏器对高龄患者术后生活质量及预后的影响。方法:136例大于70岁的高龄患者安装起搏器术后(3.5±2.1)年,观察生活质量分级、运动能力、生存率、心功能等指标。结果:两组起搏器术后生存率无明显差异(93.7%与94.2%,P>0.05)。运动总时间、距离、生活质量均明显改善,但两组对比无明显差异。起搏器综合征仅发生于单心室起搏者(27.1%)。单心室起搏者术后左房内径(3.82±0.21)大于双腔起搏者(3.38±0.41),心功能两组间无差别(P<0.05)。结论:无论是单心室起搏还是双腔起搏术后均能满足高龄患者的基本生活需求、改善生活质量,双腔起搏更能满足老年患者心脏生理特性。

AIM:To contrast the effect of either ven tricular pacemaker or dual-chamber pacemaker on the quality of life and c linical outcomes in elderly patient s.METHODS :The survival rate,the level of quality of life,movement abil-ity,heart function etc.were observ ed in 136patients 70years of age or older after(3.5±2.1)years of the pacemaker implantation.RESULTS:The survival rate was no difference betw een the two pacemakers(93.7%vs94.2%,P>0.05).Quality of life,daily maximum move ment time and distance were improved significant ly after pacemaker implantation,but no different between the two pacemakers.The pacemaker syndrome only was found in the patients implanted vent ricular pacemaker.Left atrium diam eter is larger in the patients implanted v entricular pacemaker than the patie nts implanted dual-chamber pacemaker(3.82±0.21vs 3.38±0.41,P<0.05).Heart functions were no different i n the two pacemakers.CON-CLUSION:The implantation of a permanent pacemaker either ventricular pacemaker or dual-chamber pacemaker all improves health-related quality of life,meet with requirement of life i n the elderly patients.Dual-chamber pacemaker is believed to be more physiologic.
