Abstract:ObjectiveTo investigate efficacy of CRT treatment in elderly patients with heart failure and to analyze nonresponse causes.Methods31 elderly patients with heart failure in our hospital from October 2011 to November 2013 were selected and divided into the response group and the non-response group according to the results of CRT treatment.Heart function,clinical indexes were analyzed.ResultsThe treatment efficiency was 77.4%.After CRT,QRS wave duration in response group showed narrow while wide in non-response group.Classification of cardiac function in response group improved.LVEF and 6 min walking distance increased.Scar area integral,transmural extent,volume integral decreased,Nt-BNP reduced (P<0.05).Preoperative left ventricular scar load,left ventricular electrode position and QRS wave duration were influencing factors of CRT treatment in elderly patients with heart failure.ConclusionCRT is an effective method in the treatment of elderly patients with heart failure,which can improve cardiac function.Non-response of CRT may be associated with left ventricular electrode position,complications,cardiac dyssynchrony.
