Answer

In a single-center, case-control study that included 188 patients with RAS, Meredith and colleagues identified previous myocardial infarction, left ventricular ejection fraction (LVEF) ≤35%, and GFR ≤45 mL/min/1.73 m2 as risk factors. Renal artery stenting was associated with a 43% reduction in mortality in patients with one or one of those risk factors, but stenting had no effect on mortality in patients with two or three risk factors.
