Résumé

Contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) is frequent and associated with long-term renal impairment and mortality. Early markers of CIN are needed to improve risk stratification. We aimed to assess whether N-terminal fragment of pro B-type natriuretic peptide (Nt-proBNP) could be associated with CIN. From the French regional RICO survey, all the consecutive patients who underwent primary PCI for STEMI, from January 1, 2001, to December 3, 2013, were included. Nt-proBNP circulating levels were assessed on admission. CIN was defined as an increase in serum creatinine >26.5 μmol/L or >50% within 48 to 72 hours after PCI (KDIGO criteria). Of the 1,243 patients included, CIN occurred in 130 patients (10.4%). Nt-proBNP levels were 5 times greater in patients who developed CIN than without CIN (1,275 [435 to 4,022] vs 247 [79 to 986] pg/mL, p <0.001). Hospital mortality rate was markedly higher in patients with CIN (6.9% vs 1.1%, p <0.001). Nt-proBNP levels were univariate predictors for CIN as were age, hypertension, diabetes, smoking, previous stroke, heart rate, impaired left ventricular ejection fraction C-reactive protein, history of renal failure, anemia, and estimated glomerular filtration rate <30 ml/min/1.73 m(2) at baseline. Nt-proBNP levels remained strongly associated with the occurrence of CIN even after adjustment for risk factors, treatments, clinical and biological variables (odds ratio 1.99, 95% confidence interval 1.49 to 2.66). Net reclassification improvement was achieved by the addition of Nt-proBNP to the risk model (p = 0.003). In conclusion, from this large contemporary prospective study in nonselected population, our work suggests that Nt-proBNP levels at admission could help to identify patients at risk of CIN beyond traditional risk factors.
