End-stage renal disease is a situation that predisposes the patients to cardiovascular disease, especially myocardial infarction (MI). A valuable biomarker for the diagnosis of this event is cardiac troponin. Although some asymptomatic patients show high plasma levels of cardiac troponin I, it is still the most sensitive variable in MI. All patients more than 18-year-old, on chronic ambulatory peritoneal dialysis (CAPD) for at least three months, and did not have a history of acute myocardial infarction or hospitalization for CVD during last month are included in a cross-sectional descriptive study. Troponin I serum level was measured by VIDAS Troponin I Ultra (TNIU) Assay. Correlation between serum troponin level and cardiovascular risk factors are evaluated. In this study, 52% of patients were male. The mean cTnI level was 0.025±0.044 ng/mL, less than 0.11 ng/mL, and only five patients had cTnI level more than the laboratory threshold. The cut-off level of cTnI for diagnosing cardiovascular disease must be re-evaluated and maybe increase to 0.3 ng/mL. Indeed, the asymptomatic patient may need more close observation for cardiovascular disease. © 2019 Tehran University of Medical Sciences. All rights reserved.
