Age and hypertension

 In one's life, the blood pressure value is not constant. In normal physiological conditions, the blood pressure value varies with age, sex and other factors. The increase of systolic pressure was more significant than that of diastolic pressure, which was manifested by the increase of pulse pressure difference. This is due to the increase of age, the proliferation of collagen fibers, gradually replacing smooth muscle and elastic fibers, resulting in the decrease of vascular wall elasticity. The increase of blood pressure in men was higher than that of women, but after menopause, the difference between men and women decreased.
