1、特 点,一 涉及面广二 定义及诊治程序不规范三 参考资料少四 预后差,七个流程,理清思路,第一步（Step one）定义是否准确,第二步（Step Two）排除假性难治性高血压,排除假性难治性高血压Exclude Pseudoresistance,依从性：40%中断治疗（新诊断的第1年）40%继续治疗（以后5-10年）16%白大衣效应：在难治性高血压中更常见约20%-30%,血压测量不准确,第三步（Step Three）鉴别和逆转生活方式,Franminghanm研究60-70%的高血压病人有肥胖，并随年龄增加。在高血压肥胖病人中75%不限盐饮食，当体重减轻10kg血压达正常。肥胖高血压病人减

2、肥比限盐更重要,肥胖,obesity is a common feature of patients with resistant hypertension.Mechanisms of obesity-induced hypertension are complex and not fullyelucidated but include impaired sodium excretion,increased sympathetic nervous system activity,and activation of the renin-angiotensin-aldosterone system

3、.,体力活动与血压,1983年美国哈佛大学男性校友随访6-8年的结果表明，体力活动指数及是否参加剧烈运动项目（跑步、游泳、手球、网球、平地滑雪等）与高血压发病率呈副相关。每周参加运动项目的时数越多，发生高血压的危险就越低。,Dietary Approaches Stop Hypertension饮食控制终止高血压,U.S.DEPARTMENT OF HEALTH AND HUMAN SERVICES National Institutes of Health National Heart,Lung,and Blood Institute,NIH Publication No.06-4082Or

5、病率高 临床症状不典型预后差（but also because PA patients have higher cardiovascular morbidity and mortality than age-and sex-matched patients with essential hypertension and the same degree of blood pressure elevation）可治疗性或可治愈性疾病,原醛的疑惑,一 血压并不顽固二 血钾不低三 肾素不低四 醛固酮不高 五 影像学与临床不符 六 手术后血压仍然高,How frequent is hypokalemia

6、 in PA?In recent studies,only a minority of patients with PA(937%)had hypokalemia.Thus,normokalemic hypertension constitutes the most common presentation of the disease,with hypokalemia probably present in only the more severe cases.Half the patients with an APA and 17%of those with idiopathic hyper
