Background: Radiographic contrast media exposition can cause acute renal function impairment. There is limited and conflicting evidence that hydration with sodium bicarbonate prevents contrast-induced nephropathy (CIN) in patients undergoing cardiac catheterization.
Background: Patients with chronic kidney disease (CKD) submitted to coronary angioplasty have higher rates of target lesion revascularization (TLR) and mortality. Drug-eluting stents (DES) are associated with a lower rate of restenosis, compared to bare metal stents (BMS), although data on DES efficacy and safety is limited in patients with CKD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
