(gold standard test) ;治疗：treatment 经皮肾动脉成形术 手术治疗：血运重建；肾移植；肾切除 药物治疗:不适宜上述治疗的可采用药物治疗 双侧肾动脉狭窄、肾功能已受损或非狭窄侧肾功能较差的患者禁用ACEI或ARB;病因及发病机理： 肾上腺皮质增生或肿瘤分泌过多的醛固酮，导致水钠潴留所致(aldosterone-producing adenoma70-80%,idiopathic hyperaldosteronism 20-30%. 诊断：excessive production of aldosterone , sodium retention, weight gain, hypertension,hypokalemia and metabolic alkalosis, 多数患者长期低血钾，有无力、周期性麻痹、烦渴、多尿等症, 血压轻、中度升高 实验室检查低血钾、高血钠、代碱, 血浆肾素活性降低，血尿醛固酮增多（醛固酮/肾素 ）, 超声、放射性核素、CT可确定病变性质和部位。 治疗：首选手术治疗 肾上腺皮质增生术后仍需降压治疗，宜选择螺内酯和长效钙拮抗剂;病因：the 4th leading cause of congenital heart disease 诊断： Diminished femoral pulses and a systolic pressure gradient between BPs obtained in the arms and legs上肢血压增高而下肢血压不高或反而降低 A loud systolic murmur 肩胛间区、胸骨旁、腋部有侧枝循环的动脉搏动和杂音、腹部听诊血管杂音 3 sign :胸片见肋骨受侧支动脉侵蚀引起的切迹 Definite diagnosis requires aortography;主动脉造影可确定诊断 治疗：surgery ;发病机制： 90% arise from adrenal gland,嗜铬细胞间歇或持续释放过多肾上腺素、去甲肾上腺素、多巴胺 诊断： five Hs: hypertension , headache,hypermetabolism, hyperhydrosis,hyperglycemia,典型的发作表现为阵发性血压升高伴心动过速sinus tachycardia、头痛、出汗、面色苍白 24-hr urine for metanephrines,VMA,catec
