收缩压高什么原因（What is the cause of the systolic pressure） Diastolic blood pressure: This is mainly due to increased peripheral resistance. What is the patients age? As the age increases, the peripheral blood vessels will harden, resulting in an increase in peripheral resistance and an increase in diastolic blood pressure. Your age, the general hypertension systolic and diastolic blood pressure will rise, and the systolic pressure will be significantly higher than the diastolic blood pressure There is a kind of high blood pressure is easy to happen in young adults, and diastolic blood pressure as the main performance, namely the accelerated hypertension... this is a more urgent, hypertension incidence, of course, also will be more serious, suggest you go to a hospital making early system inspection, early diagnosis would be better High systolic blood pressure: + + old peoples blood pressure is increased by simple systolic blood pressure, which is a characteristic of high blood pressure, so it is also called simple systolic hypertension or old systolic hypertension. The major factors affecting blood pressure were related to the size of myocardial contractile force and the amount of cardiac output and the elastic size of the arterial wall. The systolic pressure increases when the myocardial contractions increase, the blood flow increases, and the walls of the blood vessels are less elastic. The reasons for diastolic pressure mainly depend on the elasticity of the peripheral blood tube resistance and the arterial wall. When the vascular resistance decreases and the elasticity decreases, the diastolic blood pressure decreases. Due to the decreased elasticity of the aorta, the vascular conformance decreased, so the systolic blood pressure increased, while the diastolic pressure decreased and the pulse pressure increased. Through 24-hour dynamic blood pressure monitoring, systolic blood pressure increased with age, while diastolic blood pressure decreased gradually and decrease
