The Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study has shown that when added to a background optimal medical therapy, renal artery stenting provides no incremental benefit in people with atherosclerotic renal artery stenosis and either hypertension or chronic kidney disease. Specifically, renal artery stenting did not reduce the composite endpoint of death from cardiovascular or renal causes, MI, stroke, hospitalization for congestive heart failure, progressive renal insufficiency, or the need for dialysis. Further details are available in CardioExchange’s news coverage of CORAL.
Given these findings, should we stop screening for renal artery stenosis? Why or why not?
