Hemodiafiltration affects NT-proBNP but not ST2 serum concentration in end-stage renal disease patients

There is a significant decrease of NT-proBNP after HDF, whereas sST2 remains unaffected by HDF. Care should be taken when interpreting NT-proBNP results having regard to the time since the last dialysis. sST2 measurement can be done at any time, relative to HDF.
