原发性高血压是一种病理生理过程复杂的慢性疾病，其发病原因至今未明确。对于血压增高但不足标准高血压（120～140／80～90 mmHg，1 mmHg＝0.133 kPa）的人群，近年来引入高血压前期的概念。高血压前期是防止高血压以及避免一系列心血管疾病发生的关键时期。近年来科学家们提出了针对高血压前期系统治疗的若干模式，如饮食模式、合理运动模式、药物干预模式。但高血压前期是否需要使用药物进行干预仍是一个具有争议的问题。该文对高血压前期的饮食模式干预、运动模式疗法以及是否采用药物防治进行全面阐述。“,”Essential hypertension is a chronic disease with complicated pathophysiological process , the etiology of which is unknown yet.In recent years,prehypertension(120-140/80-90 mmHg) has been intro-duced to our life.Prehypertension period is important for controlling the onset of hypertension,thereby can avoid a series of events such as stroke and heart disease.A mount of strategies have been provided for prehy-pertension treatment including the Dietary approaches to stop hypertension ( DASH ) and proper movement patterns as well as drug intervention mode.However,whether drug intervention is necessary to the treatment of prehypertension is still controversial.Here is to make a comprehensive elucidation on each model for the prevention and control of prehypertension.
