AimsWe evaluated the effect of different dose hydration protocols, with normal saline or bicarbonate, on the incidence of contrast-induced acute kidney injury (CI-AKI) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PPCI).MethodsWe considered 592 STEMI patients treated with PPCI in 5 Italian centers. Patients were randomized to receive standard or high-dose infusions of normal saline or sodium bicarbonate started immediately before contrast medium administration and continued for the following 12 h.ResultsThe cumulative incidence of CI-AKI was 18.1% without any difference among treatment groups. Shock, age, ejection fraction 35% or less, and basal serum creatinine were significantly associated with an increased risk of CI-AKI. Follow-up at 12 months was complete in 573 patients. Overall, 25 out of 573 patients died (4.3%). We observed higher short-term mortality rates in patients receiving high-volume hydration. Otherwise, only age, shock and CI-AKI were significantly associated with 1-year mortality.ConclusionIn patients with STEMI undergoing PPCI, high-volume hydration with normal saline or sodium bicarbonate administrated at the time of contrast media administration was not associated with any significant advantage in terms of CI-AKI prevention.
