Mehran risk score model for predicting contrast-induced nephropathy after cardiac resynchronization therapy in patients with heart failure

Aims: Contrast-induced nephropathy (CIN) is a challenging condition after cardiac procedures. Mehran risk score (MS) is a simple tool for predicting CIN. We investigated the role of MS to predict CIN development following cardiac resynchronization therapy (CRT) implantation in heart failure (HF) patients. Methods: This single-center, retrospective study included HF patients who underwent CRT implantation. The patients had New York Heart Association class II-IV disease, wide QRS in electrocardiogram (>130 ms), and diminished left ventricular ejection fraction (
