Prevalence of renal artery stenosis in high-risk veterans referred to cardiac catheterization.

Objective: The prevalence of atherosclerotic renal artery stenosis (RAS) varies depending on patient selection with no specific guidelines on indications for selective renal angiography in patients referred for coronary angiography. The goal of this study is to determine the prevalence and predictors of renal artery stenosis in hypertensive veterans referred for coronary angiography.

Design: Prospective study.
