[Summary] Objective To investigate the clinical feature of chronic heart failure(CHF)in the elderly with renal dysfunction,and analyze the effect of renal dysfunction on patients after the treatment. Methods The data of 136 CHF patients who were admitted to the Department of Cardiology in Six Hospital of Beijing between 2011.1 to 2013.1..According to eGFR,evaluate patients’ renal function and divided patients into two group:the renal dysfunction group and the normal renal function or mild renal function damage group.Analyze patients’ clinical data and the mortality and hospitalization rate of repeated heart failure by logistic regression. Result Compared with the normal renal function or mild group general group,the renal dysfunction group is older, NYHA classification grade II and larger proportion of smaller percentage of Ⅳ grade, etiology coronary heart disease, heart disease share a greater proportion of diabetic complications aspect, lung infections and OMI greater proportion (p <0.05); compared with clinical symptoms, paroxysmal nocturnal respiratory difficulties, difficulties arise rate exertional respiratory and lower limb edema higher (p <0.05); compared with laboratory parameters and cardiac function tests, Hb, RBC, LVEF,GFR less, CRP, TG, GLU,BNP,NT-proBNP higher (p <0.05), compared to Clinical outcome, malignant arrhythmia, due to heart failure readmissions, recurrent coronary events and mortality rates are higher because of illness (p <0.05);By logistic regression analyze,Renal dysfunction was an independent risk factor to mortality and hospitalization rate of repeated heart failure. Conclusion The clinical features of eldly CHF patients with renal dysfunction is different from the normal renal function or mild renal function damage CHF patients.Renal dysfunction was anindependent risk factor to mortality and hospitalization of repeated heart failure.
