NCT04211610

Brief Summary

In this study, in order to better understand the mechanism of troponin clearance and the reason for elevated troponin levels in patients with CKD, we aim to evaluate quantitatively the excretion of troponin in the urine in patients with and without CKD, and with and without myocardial injury. We will compare urinary troponin levels with blood troponin levels in these patients. In addition, we will compare the levels of hs-cTnT and hs-cTnI in the patients' sera and urine.
