高血压是脑血管病重要的、独立的危险因素,收缩压与舒张压的升高都与脑卒中的发病呈正相关,并呈线性关系。研究表明[1],收缩压>160mmHg和(或)舒张压>95mmHg,卒中的相对风险约为血压正常者的4倍。作为脑卒中最常见类型的脑梗死(约为70%),急性期血压的变化规律与影响因素, Hypertension is an important and independent risk factor for cerebrovascular disease. Systolic and diastolic blood pressure are positively correlated with the incidence of stroke and have a linear relationship. Studies have shown that 1, the systolic blood pressure> 160mmHg and (or) diastolic blood pressure> 95mmHg, the relative risk of stroke is about 4 times the normal blood pressure. As the most common type of stroke in stroke (about 70%), changes in blood pressure in the acute phase and influencing factors,
