曾有人指出,血管老化是衰老的标志,亦即衰老始于血管的老化,从科学角度出发,这种认识是很有道理的。 血管的生理发育完全约在20岁左右,此时的血管柔韧而富有弹性,完全适合机体供血的需要。此后,血管的发育状态维持相对稳定,直至中年期。中年期后血管便开始了退行性变化,这是一个缓慢的过程。血管的退行性变表现为随着增龄其长度和横断面的直径增长,即血管扩张和屈曲。与此同时,血管壁
It has been pointed out that vascular aging is a sign of aging, that is, aging begins with the aging of blood vessels, from a scientific point of view, this understanding is justified. Physiological development of blood vessels completely about the age of 20, this time the flexible and flexible blood vessels, fully suited to the needs of the body’s blood supply. Since then, the development of blood vessels remained relatively stable until middle age. After the middle of the blood vessels began to degenerative changes, this is a slow process. Degeneration of blood vessels is manifested as its length and cross-sectional diameter increases with age, vasodilation and flexion. At the same time, the vessel wall
