冠心病合并肾动脉狭窄危险因素及临床意义

Risk factor and clinical significance of renal artery stenosis in patients with coronary artery disease

目的 探讨冠心病合并肾动脉狭窄发病率及危险因素 ,以及冠状动脉造影同时行肾动脉造影的必要性。方法 对 114例接受冠状动脉造影患者同时行肾动脉造影。结果 114例患者中 ,肾动脉狭窄发病率 18 4% ,经冠状动脉造影证实的 77例冠心病中肾动脉狭窄发病率 2 6 % ,冠状动脉造影正常的 37例中肾动脉狭窄发病率 2 7% ,冠心病患者中肾动脉狭窄发病率明显高于非冠心病组(P <0 0 1)。结论 冠心病患者有较高的肾动脉狭窄的发生率 ,应该在冠状动脉造影明确冠状动脉病变后 ,常规行肾动脉造影。

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<0.01). Conclusion Incidence of renal artery stenosis is higher in patients with coronary artery disease. Renal arteriography should be performed routinely after patients are identified as coronary artery disease by coronary artery angiography.
