Main characteristic _ symptom of the senile hypertension
Over age 60, the blood pressure value exceeds the diagnostic standard of hypertension 3 or more times on the same day continuously or, systolic pressure is greater than 140 millimetres of mercury columns and persons who greater thans 90 millimetres of mercury columns of the diastolic pressure, called senile hypertension. According to the investigation, the elderly about 43 over 60. 75% have hypertension, about half the among them are simple systolic phase hypertension.
Old hypertension has the following characteristics in clinical manifestation and physiological respect of the pathology:
( 1) Blood pressure fluctuation is great: Systolic pressure, diastolic pressure and difference of pulse pressure of the elderly's hypertension have greater fluctuations than the young one, especially systolic pressure. But the fluctuation by a relatively large margin of blood pressure often influences the appraisal on the overall level and therapeutic effect of patient's blood pressure, and the blood pressure fluctuation of the elderly's hypertension is not merely relatively obvious over a long time, the fluctuation in 24 hours on the 1st is greater than the young ones too. So, continuous blood pressure monitors the true level reflecting patient's blood pressure better in 24 hours.
( 2) The difference of pulse pressure is greater: Because of the elderly being obvious in arteriosclerosis, elasticity subside, the aorta can't totally swell at the cardiac ejection, the blood capacity sharply increased in the artery can not be buffered, lead to the fact systolic phase blood pressure obviously increases, and the diastolic pressure is relatively low, the difference of pulse pressure increases.
( 3) Body posture hypotension is seen more: Because the regulating function of the pressures of the elderly receptor is weakened, so, hypertension patients of the elderly see more in body posture hypotension, especially in the course of stepping down and treating. Determine patient's flat blood pressure value when lies in 10 minutes and stands for one minute and 5 minutes passively, find about 1/3 patient take place the intersection of body posture and the intersection of and hypotension, follow symptom such as being dizzy.
( 4) Malignant hypertension is rare: Most of the elderly's hypertension is light, malignant or the radical type one is rare. Shown as that the disease is slow to get up, it is slow to develop, symptom is not typical or does not has obvious subjective symptoms, often found while or erupts cerebrovascular diseases simultaneously in the physical examination.
( 5) Examine and press the law and overestimate the blood pressure value indirectly: It is difficult for the limb artery that because the elderly hardened to be oppressed, blocked the blood flow by the gasbag of the mercury type sphygmomanometer, so can obtain higher indirectness and examine and press reading. The elderly's direct and indirect blood pressure reading can differ by more than of 30 millimetres of mercury columns.
