Part in elderly patients with hypertension are adult hypertension continues, another part is due to atherosclerosis, elastic minus late systolic blood pressure to rise. Elderly hypertensive has the following characteristics:
1. the blood pressure in elderly hypertensive fluctuate greatly, especially the systolic pressure. This is mainly because the elderly patients with vascular Baroreceptor sensitivity impairment. Result in antihypertensive drug therapy should be regularly measuring blood pressure, at any time adjust the dosage.
2. the elderly hypertensive vulnerable to the effects of changes in posture, postural hypotension of high incidence. Therefore should be used with extreme caution can cause hypotension drugs such as guanethidine, α 1 receptor blocker, furosemide, etc.
3. older persons as a result of atherosclerosis prone to the phenomenon of false hypertension, hypertensive patients against hypertension drug tolerance poor. more easily lead to serious adverse reactions and serious complications. At the same time reducing speed in elderly hypertensive patients should not be too fast, you should drop too low.
4. elderly hypertensive to elevated systolic blood pressure, heart damage larger, more prone to heart failure, but also more prone to stroke.
5. old β receptor responsiveness, β receptor blockers tolerance better, but still have caused bradycardia and the risk of congestive heart failure.
6. reduce the blood volume in the elderly and sympathetic suppression sensitive, this may be and elderly cardiovascular reflex injury.
7. elderly hypertensive of antihypertensive drugs in the treatment of the initial dose and increase doses than younger patients with hypertension, interval should also long than younger patients with hypertension.
8. nervous system function in the elderly is lower, more prone to drug treatment of depression, so you should avoid using role in central nervous system of antihypertensive drugs such as clonidine, methyldopa, etc.
