Assessment of estimated GFR and clinical predictors of contrast induced nephropathy among diabetic patients undergoing cardiac catheterization

Contrast-induced nephropathy is a leading cause of morbidity and mortality in high-risk patients. To study different risk predictors of contrast induced nephropathy, among diabetic patients with normal serum creatinine undergoing cardiac catheterization. It involved 250 consecutive diabetic patients who underwent either coronary angiography or PCI. All patients were subjected to thorough history taking and clinical examination, measurement of serial serum creatinine levels and creatinine clearance prior to the procedure, 72h after and after 7days, coronary angiography or percutaneous coronary intervention, ECG, echocardiography, follow up during the first seventy-two hours for occurrence of contrast-induced nephropathy, follow up one month later for occurrence of major adverse cardiac events. 58 patients developed CIN with total incidence of 23.2%. CIN was found to be more among the patients who had PCI (40 patients, 69%, P
