In the current study, among 293 non-ACS patients with CKD, 166 (56.66%) patients had a normal cTnI level and 112 patients (38.23 %) had an elevated cTnI level (concentration 0.06-0.6ng/ml), and 15 patients (5.12%) had an elevated cTnT level in MI range. This evidence concerns the gene TNNT2 and chronic kidney disease.
