About

Although expert consensuses recommend the use of statins in the treatment of atherosclerotic renal artery stenosis, in patients with severe atherosclerotic renal artery stenosis undergoing stent placement, the related investigation focused on renal protection by intensive lipid-lowering therapy is scant , and the optimal target level for lipid reduction remain uncertain. Therefore, we hypothesized that intensive lipid lowering could offer more benefits with respect to renal function in the patients with percutaneous renal artery stenting. We conducted the prospective randomized unblinded trial to compare the renal-protective effect of intensive lipid lowering with that of conventional lipid lowering in patients underwent renal artery stenting (75 patients in each study group)
