Popis: Beta Trace Protein (BTP) is a biomarker for residual kidney function which has been linked to cardiovascular and all-cause mortality in haemodialysis patients. Following renal transplantation, recipients remain at increased risk for cardiovascular events compared with the general population. We aimed to determine the relationship of pre-transplant BTP to major adverse cardiac events (MACE) in patients following kidney transplantation.We included 384 patients with end-stage renal disease who received a kidney transplant. MACE was defined as myocardial infarction (ST-segment elevation or non-ST-segment elevation, stroke or transient ischemic attack), coronary artery disease requiring intervention or bypass or death for cardiovascular reason. The association between pre-transplant serum BTP concentration and post-transplant MACE was evaluated by Kaplan-Meier and Cox regression analyses.Post-transplant MACE occurred in 70/384 patients. Pre-transplant BTP was significantly higher in patients with post-transplant MACE (14.36 ± 5.73 mg/l vs. 11.26 ± 5.11 mg/l; p .01). Next to smoking (HR 1.81), age 56.38 years (HR 1.97) and pre-existing coronary heart disease (HR 8.23), BTP above the cut off value of 12.7 mg/l was confirmed as independent risk factor for MACE (HR 2.02, all p .05). MACE-free survival inversely correlated with pre-transplant BTP levels.Pre-transplant serum BTP concentration may identify renal transplant recipients with higher risk of post-transplant MACE.
