ABSTRACT
Aim: Cardiac troponin I (cTnI) concentration stability during dialysis have not been fully elucidated. The aim is to evaluate the effect of a single dialysis session on plasma cTnI. Patients & methods: From 122 consecutive anuric adult patients (75 [61.5%] men, age 27-86 years, median 67) on chronic hemodialysis blood samples for cTnI measurement were taken before and after a dialysis. Results: Dialysis had no effect on high-flux membranes (geometric means ratio = 0.99, 0.94-1.05, df 119, t = -0.19, multiplicity adjusted p = 0.847), but cTnI levels were higher after dialysis in patients on low-flux membranes (geometric means ratio = 1.14, 1.02-1.27, df 119, t = 2.59, adjusted p = 0.021). Conclusion: Dialysis session using low-flux membranes might increase the plasma cTnI.
