High CV mortality in renal artery stenosis persists irrespective of intervention; leaves open whether revascularization benefits select subgroups.
Does interventional treatment (renal angioplasty or surgical reconstruction) improve long-term survival compared to no intervention in hypertensive patients with renal artery stenosis?
Hypertensive patients with renal artery stenosis have significantly elevated cardiovascular mortality that is not improved by interventional treatment (angioplasty or surgery) and is not directly linked to sympathetic overactivity.
