BACKGROUND: Serum troponin-T concentrations are commonly increased in chronic kidney disease (CKD) without acute coronary syndrome. Highly-sensitive troponin-T the new tool that helpful for diagnosis of acute coronary syndrome, provides few data about normal value in patients with chronic kidney disease. MATERIAL AND METHOD: The authors studied 89 patients with CKD stage 3-5: 40 had CKD stage 3, 26 had CKD stage 4 and 23 had CKD stage 5. Serum samples were collected for the analysis of highly-sensitive troponin-T levels. The values of highly-sensitive troponin-T of the total group and each CKD stage were presented. RESULTS: The level of highly-sensitive troponin-T in patients with CKD stage 3-5 was 0.044 +/- 0.076 ng/ml. For CKD stages 3, 4 and 5 levels were 0.015 +/- 0.016, 0.043 +/- 0.056, 0.098 +/- 0.121 ng/ml, respectively. 95th percentile of the total group was 0.139 ng/ml. 95th percentile for stage 3, 4 and 5 were 0.052, 0.136, 0.297 ng/ml, respectively. CONCLUSION: 95th percentile for highly-sensitive troponin-T of patients with CKD stage 3-5 was 0.139 ng/ml. This number may be considered as the cut-off value for diagnosis of acute myocardial infarction.
