大量的循证医学证据表明,高血压是引发心脑血管事件最重要、最直接的原因之一,持续平稳地控制血压达正常目标水平,有效预防和阻止心脑血管事件的发生,控制血压达正常目标水平,是治疗高血压的关键。近年来对高血压的研究与防治备受重视,流行病学调查提示,老年高血压患者糖尿病、主动脉钙化、心肌梗死、脑卒中的发病率和心血管病死亡率以及老年人总死亡率高于同龄血压正常人。且收缩压随年龄的增加而增高,发生 A large number of evidence-based medical evidence shows that hypertension is one of the most important and direct causes of cardiovascular and cerebrovascular events. It continuously and steadily controls blood pressure to a normal target level, effectively prevents and stops the occurrence of cardiovascular and cerebrovascular events, and controls blood pressure up to The normal target level is the key to the treatment of hypertension. In recent years, great attention has been paid to the research and prevention and treatment of hypertension. Epidemiological investigation suggests that the incidence of diabetes mellitus, aortic calcification, myocardial infarction, stroke and cardiovascular disease in elderly patients with hypertension and the high total mortality in the elderly Normal blood pressure at the same age. And systolic blood pressure increased with age, occurred
