高血压是我国最常见的心血管疾病。1978年世界卫生组织(WHO)规定,成人正常血压应≤18.6/12kPa(140/90mmHg);高血压为≥21.3/12.6kPa(160/95mmHg);而临界性高血压是指血压超过正常范围,但未达到高血压标准,即舒张压在11.8～12.2kPa(91～94mmHg),收缩压在18.3～20.7kPa(141/159mmHg)。如果一个人在一月内连续测量血压,有一半时间血压超过正常,则可诊断为临界性高血压。我国约有2000万临界性高血压患者,大多为中老年人。临床主要表现为血压波动性较大,有时亦可完全正常,容易
Hypertension is the most common cardiovascular disease in our country. 1978 World Health Organization (WHO), adult normotensive blood pressure should be ≤ 18.6 / 12kPa (140 / 90mmHg); hypertension for ≥ 21.3 / 12.6kPa (160 / 95mmHg); and critical hypertension refers to blood pressure exceeds the normal range, But did not meet the high blood pressure standard, diastolic blood pressure in 11.8 ~ 12.2kPa (91 ~ 94mmHg), systolic blood pressure in the 18.3 ~ 20.7kPa (141 / 159mmHg). If a person measures blood pressure continuously in January and has blood pressure more than normal in half of the time, it is diagnosed as critical hypertension. About 20 million critical hypertensive patients in China, mostly in the elderly. The main clinical manifestations of greater blood pressure fluctuations, and sometimes also completely normal and easy
