ABSTRACT
Objective To evaluate the prognostic values of common definition compared to traditional definition of contrast-induced nephropathy (CIN) in patients with normal serum creatinine (SCr). Methods Patients undergoing percutaneous coronary angiology or intervention with normal baseline SCr were enrolled prospectively. Those who were diagnosed as CIN according to common definition were divided into two groups based on the peak increase from baseline in the SCr concentration within 48 ~ 72 hours after the procedure: ≥ 44.2 μmol/L (CIN44.2 group, in common with traditional definition), ≥25% of baseline to < 44.2 μmol/L (CIN25%-44.2 group, interval between the two definitions). Hospital stay and long-term outcomes were compared among CIN44.2, CIN25%-44.2, and non-CIN groups. Results Of all 3,044 patients enrolled, 302 (9.9%) patients developed CIN according to common definition including CIN44.2 occurred in 56 (1.8%) patients and CIN25%-44.2 in 246 (8.1%) patients. Patients in CIN44.2 group indicated significant longer hospital stay and long-term outcomes compared with non-CIN group (P < 0.05). However, patients in CIN25%-44.2 group had similar in-hospital mortality and long-term cumulative risk of major clinical adverse events (MACE) and death with non-CIN group (all, P = 1.00). Multivariate Cox proportional hazard analyses also demonstrated that CIN25%-44.2 did not associate with long-term MACE (HR 1.16, P = 0.645) and death (HR 0.98, P = 0.964) after adjusting for potential confounding factors. Conclusions For patients with normal baseline SCr, common definition based on traditional definition of CIN is unreasonable and overestimates the incidence of CIN, whose extension of traditional denifition proves no significant clinical value.
