Most patients with end-stage kidney disease (ESKD) on renal replacement therapy have elevated plasma hs-cTnT levels at baseline. The impact of hemodialysis (HD) on hs-cTnT levels remains unclear. This study aimed to determine the effect of HD in patients with ESKD and hypervolemia on plasma hs-cTnT levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective study of ESKD patients admitted to two community hospitals over a three-year period (from January 1, 2020, to December 31, 2022). All patients had hypervolemia on admission. Plasma hs-cTnT levels were measured at admission and repeated 5.5 \u00b1 0.75 hours after HD. Over the study period, 20 patients with ESKD and hypervolemia fulfilled the inclusion criteria. Two patients were diagnosed with ACS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Pre-HD and post-HD hs-cTnT were elevated in 85% of patients. The data did not follow normal distribution. The median and interquartile range (IRQ) for pre-HD hs-cTnT was 126 (154) ng\/L, and for post-HD hs-cTnT was 155 (234) ng\/L. Following a single HD session with a high-flux dialyzer, hs-cTnT levels increased in 80% of the cohort, with a mean rise of 25.6% (p = 0.0042). Mean volume removal was 2.4 L, range (1\u20135 L). Two patients were diagnosed with ACS. Mortality over the study period was 40%, with cardiovascular disease as the leading cause of death.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In ESKD patients with hypervolemia, a single HD session using a high-flux dialyzer significantly increased hs-cTnT plasma level. Pre-dialysis hs-cTnT measurements should be used as a clinical baseline when evaluating for ACS, and post-dialysis elevations should be interpreted with caution. Serial measurements may improve diagnostic accuracy. Further prospective studies are needed to clarify the mechanisms and clinical implications of these findings.<\/jats:p>\n
