Abstract

A 73-year-old former smoker with a history of hypertension and dyslipidemia presents to the emergency department with shortness of breath. His blood pressure is 160/75 mm Hg, heart rate 60 beats per minute, and respiratory rate 24 breaths per minute. Chest auscultation reveals diffuse rales, and there is 1+ pitting edema. The serum creatinine level is 1.4 mg per deciliter (124 µmol per liter) (estimated glomerular filtration rate, 52 ml per minute), and urinalysis shows 1+ protein. His condition improves after treatment with intravenous diuretics, but his systolic blood pressure remains elevated, at 170 mm Hg. Magnetic resonance angiography (MRA) reveals a diseased aorta, a high-grade ostial lesion of the left renal artery that is consistent with atherosclerotic stenosis, and a normal right renal artery. How should he be further evaluated and treated?

摘要

一名73岁有高血压和血脂异常病史的戒烟者因气短就诊于急诊科。他的血压为160/75 mmHg,心率60次/分钟,呼吸频率24次/分钟。胸部听诊发现弥漫性啰音,并有1+凹陷性水肿。血清肌酐水平为1.4 mg/dl(124 µmol/L)(估计肾小球滤过率为52 ml/分钟),尿液分析显示1+蛋白尿。经静脉利尿剂治疗后他的病情有所改善,但收缩压仍升高,为170 mmHg。磁共振血管造影(MRA)显示主动脉病变、左肾动脉起始部高度病变,符合动脉粥样硬化性狭窄,右肾动脉正常。应如何对他进行进一步评估和治疗?
