title: Effect of contrast-induced nephropathy on cardiac outcomes after use of nonionic isosmolar contrast media during coronary procedure.
abstract: Contrast-induced nephropathy (CIN) has been increasing and seems to be associated with clinical outcomes in ischemic heart disease. This study aimed to assess the incidence, predictors, and cardiac outcomes of CIN when nonionic isosmolar contrast media (iodixanol, Visipaque(®), GE Healthcare, Cork, Ireland) was used. Between January 2005 and July 2008, 510 patients (69.2 ± 9.0 years of age, 384 men) undergoing diagnostic coronary angiography (CAG) or percutaneous coronary intervention (PCI) were divided into two groups according to the development of CIN (CIN group: n=74; non-CIN group: n=436). CIN developed in 74 patients (14.5%). They were more likely to have diabetes (55.4% vs. 42.9%, p=0.045), decreased left ventricular ejection fraction (LVEF) (50.1 ± 12.6% vs. 57.7 ± 13.9%, p<0.001), and lower baseline hematocrit level (32.4 ± 5.3% vs. 36.6 ± 5.5%, p<0.001). Multiple logistic regression analysis revealed baseline hematocrit (odds ratio 0.900, 95% confidence interval 0.851-0.952, p<0.001), decreased LVEF (odds ratio 0.967, 95% confidence interval 0.949-0.986, p=0.001), and baseline creatinine level (odds ratio 2.317, 95% confidence interval 1.252-4.286, p=0.007) as independent predictors of CIN. At 1-year follow-up, patients with CIN were found to have more adverse outcomes than without CIN in Cox proportional hazards analysis (hazard ratio 13.068, 95% confidence interval 2.425-70.434, p=0.003). CIN was mostly associated with baseline creatinine level rather than CM amount using nonionic isosmolar CM. We found that patients with CIN had worse event-free survival than patients without CIN after multifactorial adjustment.
