Effect of N-Acetylcysteine on cystatin C-Based renaL function after Elective coronary angiography (ENABLE Study): A prospective, randomized trial

This study suggests that in patients with apparently normal renal function, prophylactic oral N-acetylcysteine administration is effective at preventing cystatin C-based CIN development after elective coronary angiography and/or intervention, and that serum cystatin C might be a more sensitive marker of the early CIN than serum creatinine.
