脉压增大危险多 所谓脉压,是收缩压减去舒张压的差值。随着年龄的增大,高血压病程的延长,脉压会增大。过去,人们一直以为这是一种生理现象,很多老年高血压患者常为自己“虽然高压高,但低压正常”的情况感到欣慰。事实上,这种认识是错误的。脉压是反映动脉的一项重要指标,其真正原因是动脉硬化,不仅是粥样硬化,还有纤维化。脉压大表示血管弹性差。 Pulse pressure increases the risk of so-called pulse pressure, systolic blood pressure minus the difference between diastolic blood pressure. With age, the duration of hypertension, pulse pressure will increase. In the past, people always thought that this is a physiological phenomenon, many elderly hypertensive patients often for their “high pressure, but low pressure normal” situation is pleased. In fact, this understanding is wrong. Pulse pressure is an important indicator of arteries, the real reason is atherosclerosis, not only atherosclerosis, as well as fibrosis. Large pulse pressure indicates poor vascular elasticity.
