Abstract
Introduction
Although hemodialysis is lifesaving in patients with kidney failure extensive interdialytic weight gain (IDWG) between dialyses worsens the prognosis. We recently showed a strong correlation between IDWG and predialytic values of cardiac markers. The aim of the present study was to evaluate if the cardiac markers N-terminal pro-B-type natriuretic peptide (proBNP) and troponin T were influenced by IDWG and speed of fluid removal (ultrafiltration-rate).
Methods
Twenty hemodialysis patients performed in total 60 hemodialysis (three each). Predialytic values of proBNP and troponin T and changes from predialysis to 180 min hemodialysis (180–0 min) were compared with the IDWG calculated in percent of body weight. The ultrafiltration-rate was adjusted (UF-rateadj) to IDWG: (100 × weight gain between dialysis [kg])/(estimated body dry weight [kg] × length of hemodialysis session [hours]).
Results
UF-rateadj correlated (Spearman) with (1) predialytic values of IDWG (r = 0.983, p < 0.001), proBNP (r = 0.443, p < 0.001), and troponin T (r = 0.296, p = 0.025); and (2) differences in proBNP180–0min (r = 0.572, p < 0.001) and troponin T180–0min (r = 0.400, p = 0.002). UF-ratesadj above a breakpoint of 0.60 caused more release of proBNP180–0min (p = 0.027). Remaining variables in multiple regression analysis with ProBNP180–0min as dependent factor were predialytic proBNP (p < 0.001) and the ultrafiltration-rate (p < 0.001).
Conclusion
Higher UF-rateadj during dialysis was correlated to increased levels of cardiac markers. Data support a UF-rateadj lower than 0.6 to limit such increase. Further studies may confirm if limited fluid intake and a lower UF-rateadj should be recommended to prevent cardiac injury during dialysis.
期刊介绍:
Hemodialysis International was originally an annual publication containing the Proceedings of the International Symposium on Hemodialysis held in conjunction with the Annual Dialysis Conference. Since 2003, Hemodialysis International is published quarterly and contains original papers on clinical and experimental topics related to dialysis in addition to the Annual Dialysis Conference supplement. This journal is a must-have for nephrologists, nurses, and technicians worldwide. Quarterly issues of Hemodialysis International are included with your membership to the International Society for Hemodialysis.
The journal contains original articles, review articles, and commentary to keep readers completely updated in the field of hemodialysis. Edited by international and multidisciplinary experts, Hemodialysis International disseminates critical information in the field.
