Abstract:
Objective To investigate the risk factors for cardiovascular complications in the elderly persons undergone with dialysis.Methods One hundred and eighteen patients undergone with hemodialysis(HD)or continuous ambulatory peritoneal dialysis(CAPD)at the Eastern Hospital, Tongji University, Shanghai during January 2002 to December 2006 were retrospectively analyzed.They were divided into four groups based oil their age and mode of dialysis, i.e., 44 patients in the elderly HD group(aged over 60years), 16 patients in the elderly CAPD group(aged over 60), 46 patients in medium-age HD group(aged under 60 years)and 12 patients in the medium-age CAPD group(aged under 60).Routine biochemical parameters were measured for all the patients and their difference was compared among the four groups.Logistic regression analysis was performed for the risk factors of cardiovascular complications.Results Pulse pressure(PP)was(66±21)mm Hg, serum level of triglycerides(TG)was(1.28±0.67)mmol/L, serum level of lipoprotein(a)[LP(a)]was(434±202)mg/L, C-reactive protein was(CRP)(21±15)mg/L, serum phosphorous(P3-)was(2.02±0.77)mmol/L, and product of serum calcium and phosphorous(Ca×P)was(4.3±1.6)mmol2/L2, respectively, in the elderly group with dialysis, all significantly higher than those in the medium-age group with dialysis(t=1.535, 1.016, 2.154, 2.252, 4.676, and 4.534, respectively, P＜0.05).Incidence of cardiovascular events was markedly lower in the CAPD group than that in the HD group(P＜0.05), either in the elderly or medium-aged patients.And, incidence of cardiovascular complications correlated positively with age, PP, LP(a), CRP and Ca×P of the patients with dialysis, but correlated reversely with serum level of albumin(all with P＜0.05).Conclusions There exist a few risk factors for cardiovascular complications in the elderly patients with dialysis, so proper mode of dialysis should be selected for those who need it and adequate intervention should be implemented for them to correct the risk factors.
