老年高血压的发病与血压调节中枢功能减退和硬化性血管壁僵硬度增加有关，临

The incidence of hypertension in the elderly is related to the decrease of central function of blood pressure regulation and the increase of the stiffness of the sclerosing blood vessel wall. The clinical manifestations are: ① The systolic blood pressure increases, and the systolic blood pressure increases with age; ②The pulse pressure is large, and the elderly patients with hypertension simply account for 60% of systolic hypertension. The greater the pulse pressure, the greater the risk of death;

老年高血压的发病与血压调节中枢功能减退和硬化性血管壁僵硬度增加有关，临床表现为: ①收缩压增高，收缩压随年龄增大而升高，舒张压于 50 ～ 60 岁开始下降; ②脉压大，老年高血压患者单纯收缩期高血压占 60% ，脉压越大，死亡风险越大;

The incidence of hypertension in the elderly is related to the decrease of central function of blood pressure regulation and the increase of rigidity of sclerotic vascular wall. The clinical manifestations are as follows: ① the systolic pressure increases, the systolic pressure increases with the increase of age, and the diastolic pressure begins to decrease at the age of 50-60; ② the pulse pressure is high, the pure systolic hypertension accounts for 60% in the elderly patients with hypertension, the higher the pulse pressure, the greater the risk of death;<br>
