Risk factor and clinical significance of renal artery stenosis in patients with coronary artery disease / 中国介入心脏病学杂志

ABSTRACT

Objective To explore the incidence and risk factor of renal artery stenosis in patients with coronary artery disease and essentiality of renal arteriography while performing coronary artery angiography. Methods Renal arteriography was performed immediately after coronary artery angiography in 114 patients with suspected coronary artery disease. Results Incidence of renal artery stenosis was 18.4% (21/114) in 114 patients and 26% (20/77) in patients with coronary artery disease who were identified by coronary artery angiography. Only one case with renal artery stenosis was found in 37 cases whose coronary arteries were normal (2.7%, 1/37). Incidence of renal artery stenosis in patients with coronary artery disease was higher than that in patients with normal coronary artery (26% vs 2.7%, P
