Contrast-induced nephropathy in 532 patients undergoing coronary intervention / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the incidence of contrast-induced nephropathy(CIN)in non-selected patients undergoing coronary angiography and intervention,and to investigate,the clinic risk factors of CIN as well as the renal safety of isosmolar iodixanol.Methods A total of 532 patients undergoing diagnostic coronary angiography or percutaneous coronary intervention were enrolled.Serum creatinine(SCr)was measured at any time within a week before the procedure and 2 days(48 hours)post procedure.The definition of CIN is the increase of serum creatinine of 44.2 ?mol/L(0.5 mg/dL)or 25% of the baseline at 48 hours after the use of contrast media.The effects of contrast media on renal function in patients undergoing coronary intervention were investigated and predictors of CIN were determined using logistic regression test.Results(1)Among the 532 patients,CIN occurred in 29 patients and the incidence of CIN in non-selected patients was 5.5%.(2)The incidence of CIN was significantly higher in patients with baseline eGFR
