Key result
Routine renal artery stenosis screening during cardiac catheterization proves unjustified given a low ~14% yield.
Why the study?
Does routine screening for renal artery stenosis during cardiac catheterization yield a high frequency of significant renovascular hypertension?
Population
102 consecutive patients undergoing cardiac catheterization
Design
Cross-sectional

Does not support routine renal artery screening; cross-sectional data leave open selective evaluation in hypertensive subgroups.

Does routine screening for renal artery stenosis during cardiac catheterization yield a high frequency of significant renovascular hypertension?
Routine screening for renal artery stenosis during cardiac catheterization is not justified due to the low frequency of significant renovascular hypertension.
Ramírez et al. (1987) conducted a cross-sectional in Patients having cardiac catheterization (n=102). Routine screening for renal artery stenosis was evaluated on Incidence of renal artery stenosis. Routine screening for renal artery stenosis during cardiac catheterization identified stenosis in 13.7% of patients, with only 5 having >50% narrowing, suggesting routine screening is unjustified.
