Abstract:
Objective To study the association between renal dysfunction and platelet parameters in elderly patients with early heart failure (HF).Methods 637 patients (350 old-aged and 287 middle-aged) with hypertension,CHD,T2DM admitted to our hospital from January 2013 to December 2014 served as a disease group and 464 subjects (229 old-aged and 235 middle-aged) selected from the 973 Aging Project in September 2007-June 2008 served as a healthy group.Their eGFR and platelets (PLT) were calculated,their plateletcrit (PCT) and mean platelet volume (MPV) were measured.Association between platelet parameters and renal dysfunction was analyzed by binary logistic regression analysis.Results The MPV and PCT were significantly lower in the old-aged disease group than in the old aged healthy group (9.78± 1.45 vs 10.66±0.78,P＜0.01;19.79 ± 6.21 vs 21.82 ± 6.04,P＜0.01).The PLT and PCT were closely associated with the eGFR in two groups (P＜0.05,P＜0.01).Binary logistic regression analysis indicated that the median and high PLT in disease group and the median PLT in healthy group were independently associated with renal dysfunction (OR=0.560,95％CI:0.315-0.996;OR=0.480,95％CI:0.262-0.879;OR=0.483,95％CI:0.249-0.936,P＜0.05).Conclusion Attention should be paid to the effect of PLT and their functional activity on renal function in treatment of early HF patients because aging-induced change of PLT and their functional activity are associated with renal dysfunction.
