Orthostatic hypotension, older people have to guard against

Along with the growth of the age, the body of the aging process is associated with the presence of the baroreflex response decreased, vascular compliance is reduced, vestibular reflex sympathetic attenuation, so orthostatic hypotension incidence increased significantly, caused the widespread concern of scholars home and abroad, has become a hot topic. Therefore, orthostatic hypotension, older people have to guard against!

Old friends, when you stand up giddy, micturition syncope when collapsed, activities, headache, dizziness, weakness, standing instability, difficulty urinating, might think about whether hypertension or diabetes, but never think of is orthostatic hypotension caused by. Medical treatment when most doctors are measured in patients sitting blood pressure or supine blood pressure, if only measured supine blood pressure, may also measure is that hypertension, hypotension of long term misdiagnosis.

Along with the growth of the age, the body of the aging process is associated with the presence of the baroreflex response decreased, vascular compliance is reduced, vestibular reflex sympathetic attenuation, so orthostatic hypotension incidence increased significantly, caused the widespread concern of scholars home and abroad, has now become a hot topic.

Researchers at Harvard Medical School in the United States in 2007 and 2008 published an article on this problem, relevant epidemiological survey, in more than 65 in a population of orthostatic hypotension in the prevalence rate of 20%, more than 75 years in the population prevalence of 30%, in a nursing home in the probability is greater than 50% or higher.

Orthostatic hypotension and the elderly in falls, fractures, ischemia, myocardial infarction, syncope, and increased mortality. In the research of this problem, must take into account the possible etiologies, including neurodegenerative diseases, amyloidosis, diabetes, anemia, vitamin deficiency.

Although our country has entered the aging society, but related to orthostatic hypotension in the elderly subject related information is little, this problem should be paid more attention to.

When it comes to orthostatic hypotension, we must first understand the lying and standing blood pressure, lying and standing blood pressure should be in the patient supine after 2 minutes, as well as from a lying position quickly stood up after 1～ 3 minutes should be recorded heart rate measurement, at the same time. If from the supine position to stand up after 1 to 3 minutes at least decreased systolic blood pressure within 20 mm Hg ( or a diastolic blood pressure decrease of 10 mm Hg ), can be defined as orthostatic hypotension, which is sympathetic vasoconstrictor nerve failure typical performance. Conditional person can also do the head-up tilt test.

Patients with orthostatic hypotension can be divided into two groups, symptomatic patients and asymptomatic group. Symptomatic patients often change in body position, such as a sudden from a lying position, squatting, sitting stand up when symptoms, including dizziness, fatigue, nausea, syncope, cognitive disorders, headaches, may also appear blurred vision, neck pain, shoulder pain ( called the clothes rack headache ), some patients may appear angina pectoris ( decreased myocardial perfusion ). Especially, the asymptomatic group of patients also falls and syncope.
