单纯收缩期高血压是中、老年人高血压的特点。流行病学研究发现,舒张压在男性45～55岁、女性55～64岁以后,就不再升高,并有下降趋势;但收缩压男女可上升到80岁左右,以致高低压之间的脉压差逐渐增大,这样就形成了典型的单纯收缩期高血压。其原因主要是血管系统不同程度的动脉粥样硬化所致,即大动脉弹性下降,心脏收缩时,搏出的
Simple systolic hypertension is characterized by hypertension in the elderly. Epidemiological studies found that diastolic blood pressure in men 45 to 55 years old, women 55 to 64 years old, no longer increased, and a downward trend; but men and women can rise to 80 years of systolic blood pressure, so that between the high and low pressure Pulse pressure gradually increased, thus forming a typical simple systolic hypertension. The reason is mainly due to atherosclerotic vascular system to varying degrees, that is, decreased aortic elasticity, cardiac contractions, stroke out
