What is elderly hypertension? Elderly hypertension refers to those who are older than 65 years old, whose blood pressure value continuously or more than three times in different days exceeds the standard blood pressure diagnosis standard, that is, systolic blood pressure & Ge; 21.3kpa (160mmhg) and / or diastolic blood pressure & Ge; 12.6kpa (95mmhg).
In recent years, great progress has been made in the study of hypertension in the elderly. It is believed that it has the following characteristics:
1. Complications and complications of the elderly due to physiological dysfunction, therefore, high blood pressure is easy to cause heart, brain, kidney complications, such as angina, myocardial infarction, stroke, renal dysfunction, etc., at this time, special attention should be paid to, do not use the drugs that aggravate the disease at the same time.
2. The blood pressure fluctuation is high in activity and low in quiet; it is high in winter and low in summer, and the higher the blood pressure is, the more obvious the seasonal fluctuation is. Within 24 hours, as well as in a long period, there are large fluctuations, prone to postural hypotension. This is related to the decreased sensitivity of the pressure sensing organs in the elderly to regulate blood pressure.
3. There is a large difference between systolic and diastolic blood pressure. The organs of the elderly show degenerative changes, especially in the cardiovascular system. Arteriosclerosis is obvious and almost becomes an inelastic pipe. During the cardiac ejection, the aorta could not fully expand, and the blood volume in the artery could not be buffered, resulting in the increase of systolic blood pressure, while the diastolic blood pressure was relatively low, resulting in the increase of pulse pressure difference.
