Clinical characteristics useful in screening for renovascular disease.
In an effort to detect renovascular hypertension, clinical characteristics are used to select patients likely to have renal artery stenosis. We prospectively evaluated the ability of commonly used clinical features to predict the presence of renal artery stenosis in 100 hypertensive adults. All subjects had conventional renal arteriography. Renal artery stenosis was diagnosed if there was 50% or more stenosis of a main renal artery. Eighteen of the 100 had renal artery stenosis. The presence of a bruit was strongly associated with renal artery stenosis (P less than .0005). In patients without a bruit, only refractory hypertension was associated with the presence of renal artery stenosis (P = .051). These data suggest that a bruit and refractory hypertension are associated with renal artery stenosis, but that other clinical features investigated may not be and that other means of screening for renovascular disease are needed.
