目的 探讨冠心病患者肾动脉狭窄发生率及危险因素,以了解冠状动脉造影患者同时行肾动脉造影的必要性。 方法 对169例接受冠状动脉造影患者同时行肾动脉造影,其中男性76例,女性93例,年龄60~81岁,平均(69±8)岁。本组患者临床表现高血压80例,糖尿病27 例,高脂血症36例,肾功能不全17例,低钾血症11例。 结果 169 例患者中,肾动脉狭窄33 例,发生率为19 5%。经过冠状动脉造影证实的70 例冠心病患者中肾动脉狭窄19 例,检出率为27 1%;冠状动脉造影正常的99例患者中肾动脉狭窄14例,检出率为14 1 %,冠心病患者中肾动脉狭窄发生率明显高于非冠心病组(P<0 05),且冠心病患者三支病变的肾动脉狭窄发生率明显高于单、双支病变(P<0 01)。 结论 冠心病患者中肾动脉狭窄发生率高,冠状动脉造影同时行肾动脉造影有助于提高肾动脉狭窄的临床检出率。
Objective To investigate the incidence and risk factors of renal artery stenosis in patients with coronary heart disease (CHD) to understand the necessity of concurrent renal artery angiography in patients undergoing coronary angiography. Methods 169 patients undergoing coronary angiography underwent simultaneous renal artery angiography, including 76 males and 93 females, aged from 60 to 81 years with an average of (69 ± 8) years. This group of patients with clinical manifestations of hypertension in 80 cases, 27 cases of diabetes, hyperlipidemia in 36 cases, renal insufficiency in 17 cases, hypokalemia in 11 cases. Results Of 169 patients, 33 cases of renal artery stenosis, the incidence was 19.5%. Coronary artery angiography confirmed 70 cases of coronary artery stenosis in 19 cases, the detection rate was 27 1%; 99 cases of normal coronary angiography in renal artery stenosis in 14 cases, the detection rate was 14 1%, the crown The incidence of renal artery stenosis in patients with heart disease was significantly higher than that in non-coronary heart disease patients (P <0.05). The incidence of renal artery stenosis was significantly higher in patients with three-vessel disease than those with single or double vessel disease (P <0.01). Conclusion The incidence of renal artery stenosis in patients with coronary heart disease is high. Coronary angiography at the same time can improve the clinical detection rate of renal artery stenosis.
