Stenting Does Not Improve Outcomes for Patients with Narrowed Renal Arteries

In a new study, renal-artery stenting did not confer significant benefits with respect to preventing clinical events when added to comprehensive, multifactorial medical therapy in people with atherosclerotic renal-artery stenosis and hypertension or chronic kidney disease. The NEJM results pertain to The CORAL (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) study, which involved 947 participants at more than 100 sites in various countries. Participants were randomly assigned to medical therapy plus renal-artery stenting or medical therapy alone, with a median follow-up of 3.6 years. During follow-up, there was a consistent modest difference in systolic blood pressure favoring the stent group.
