Key result
Significant renal artery stenosis was present in 29% of patients with significant coronary artery disease compared to 10% of patients without coronary artery disease.
Why the study?
What is the incidence of significant renal artery stenosis identified by screening abdominal aortography in patients with hypertension and/or renal insufficiency undergoing coronary angiography?
Population
118 patients with a history of hypertension and/or renal insufficiency undergoing routine coronary angiography
Design

May support targeted RAS screening during coronary angiography; cross-sectional data leaves open outcome impact and need for prospective trials.
Cross-Sectional (n=118)
What is the incidence of significant renal artery stenosis identified by screening abdominal aortography in patients with hypertension and/or renal insufficiency undergoing coronary angiography?
Absolute Event Rate: 29% vs 10%
Screening abdominal aortography during routine coronary angiography identifies significant renal artery stenosis in 23% of patients with hypertension and/or renal insufficiency, suggesting it is a useful screening tool in this population.
Vetrovec et al. (1989) conducted a cross-sectional in Hypertension and/or renal insufficiency (n=118). Significant coronary artery disease vs. No significant coronary artery disease was evaluated on Significant renal artery stenosis (> 50%). Significant renal artery stenosis was present in 29% of patients with significant coronary artery disease compared to 10% of patients without coronary artery disease.
