What Postural hypertension is

Definition of postural hypertension

Postural hypertension refers to a systolic blood pressure increase of at least 20mmHg after standing.The incidence of postural hypertension in various studies ranged from 8.7% to 16.3%.

Characteristics of postural hypertension

The characteristic of this disease is that it does not have the characteristic of hypertension generally, most are found in physical examination or accidental situation, its blood pressure is given priority to with diastolic blood pressure rise more, and fluctuation range is larger. 

The individual severe person may accompany palpitation, easily tired, fall asleep to wait quickly. Blood test plasma renin activity is higher than normal people, even more than the general hypertensive patients.

Causes of postural hypertension

The mechanism of postural hypertension is generally believed to be related to the excessive filling of the "gravitational vascular pool" of veins and sinus veins.

The veins and sinuses below the horizontal level of the human heart swell when they are affected by the gravity of the blood. Medically, these veins or sinuses are called gravitational vascular pools. When people lie low is not affected by what these vessels pool, but when standing or sitting position, as a result of clogged in droop too vein in the pool of blood vessels, reduce reflux flow of blood, decreased cardiac output, resulting in excessive sympathetic nervous excitement, systemic small blood vessels, especially small artery prolonged contraction or spasticity, causing increased blood pressure. Some people are particularly sensitive to this reaction, so can produce postural hypertension.

Treatment of postural hypertension

• For postural hypertension, generally do not use antihypertensive drug treatment. If the use of antihypertensive drugs, such as diuretics, not only can not reduce blood pressure but will stimulate blood pressure to further increase, therefore, the main treatment is to strengthen physical exercise, improve muscle fullness, individual symptoms are obvious, can be appropriate to take brain rehabilitation, inosine, vitamin B, glutamate, etc., to regulate the nerve can be.

• Postural hypertension also has an outstanding problem because its pathogenesis is different from that of general hypertension, so it can not be used to treat general hypertension to treat postural hypertension. Experiments have shown that the use of diuretics does not lower blood pressure, but encourages it to rise further. Position, therefore, main is to strengthen physical exercise for the treatment of high blood pressure, increase the degree of muscle fullness, generally do not need medication treatment, individual symptoms, appropriate neural function regulating drugs (such as oryzanol, etc.), the central and peripheral nerve nutrition preparation, stability and calm.

Postural hypertension generally has a good prognosis, without long-term adverse consequences, but in the diagnosis, it should be clear whether it is postural hypertension, so as not to use unnecessary or wrong treatment measures, affecting the physical and mental health of patients.
