高血压是指体循环动脉血压高于正常,是严重危害人类健康的常见病和多发病,也是心脑血管疾病发病的主要因素[1]。血压随着年龄增长而不同,而且在不同的生理情况下有一定的波动幅度。现代研究发现,大多数心脑血管事件,如心肌梗死、心肌缺血、心脏性猝死、脑卒中等的发生与血压波动有密切关系。 Hypertension refers to systemic arterial blood pressure higher than normal, is a serious risk to human health common and frequently-occurring disease, but also the main factor in the pathogenesis of cardiovascular and cerebrovascular diseases [1]. Blood pressure varies with age, but also in a variety of physiological conditions have a certain degree of volatility. Modern research found that most cardiovascular and cerebrovascular events, such as myocardial infarction, myocardial ischemia, sudden cardiac death, stroke and other occurrence and blood pressure fluctuations are closely related.
