近20余年来,由于口服降压药大量问世,高血压接受治疗人数明显增加。据美国国家健康调查,在60年代早期对高血压的检测与诊治不到患者1/8;而70年代后期已达1/2以上。大量治疗试验证明,控制高血压明显减少了卒中、心衰、肾脏损害及夹层动脉瘤等并发症的罹病率与死亡率。美国退伍军人管理局协作组的研究,有力地证实了降压对中度及重度高血压(舒张压105～114及>115mmHg)的治
The past 20 years, due to the large number of oral antihypertensive drugs available, the number of patients receiving hypertension increased significantly. According to the National Health Survey, less than one-eighth of patients tested and diagnosed with hypertension in the early 1960s; in the late 1970s, it was more than one-half. Numerous treatment trials have demonstrated that controlling hypertension significantly reduces morbidity and mortality from complications such as stroke, heart failure, kidney damage, and dissecting aneurysms. A study by the US Veterans Administration Collaborative Group strongly corroborated the antihypertensive effect of moderate and severe hypertension (diastolic blood pressure 105 to 114 and> 115 mm Hg)
