The association of hs-cTnI with measures of renal function in patients with CKD [eGFR < 60 mL min⁻¹ (1.73 m²)⁻¹] by Pearson’s correlation coefficient, and compared hs-cTnI levels between patients with or without AMI. There was a low but significant correlation between hs-cTnI and renal function in CKD patients without AMI (r² = 0.067, P < 0.001), but there was no correlation in CKD patients with AMI (r² = 0.003, P = 0.23). Furthermore, we found that CKD could result in the elevation of hs-cTnI without AMI.
