Clinical symptoms of orthostatic hypertension?

summary

The so-called orthostatic hypertension (OHT) usually refers to the increase of blood pressure in the standing position and the normal blood pressure in the supine position. This disease generally does not have the characteristics of hypertension, most of them are found in physical examination or accidental cases, and their blood pressure is mainly increased diastolic blood pressure, and the fluctuation range is large. Clinical symptoms of orthostatic hypertension? Let's talk about it

Clinical symptoms of orthostatic hypertension?

The human body has veins and sinuses below the heart level. When the human body is affected by the gravity of blood, these veins and sinuses will expand. These veins and sinuses are called "gravity vascular pool". In upright or sitting position, due to excessive blood stagnated in the venous cistern of the lower half of the body, the amount of blood flowing back to the heart is reduced and the cardiac output is reduced,

Lead to sympathetic nerve over excited, systemic small blood vessels, especially small arteries in a state of contraction or spasm for a long time, resulting in increased blood pressure. Some people are particularly sensitive to this reaction, which can lead to OHT. The maintenance of stable blood pressure is affected by neurohumoral factors, including sympathetic nervous system and renin angiotensin aldosterone system (RAAS).

When the aortic arch and carotid sinus baroreceptor feel the change of SBP, they also adjust cardiac output by contracting peripheral blood vessels, and maintain a relatively constant perfusion pressure. The increase of DBP was mediated by the cardiopulmonary baroreceptor. Blood vessels are highly sensitive to norepinephrine, causing baroreflex and OHT. Multiple factors lead to OHT.

matters needing attention

1. Whether it's sitting or squatting for a long time, remember to get up too fast and get up slowly. 2. Normal work and rest, daily continuous sleep time should be maintained at 7-8 hours, prohibit staying up late, all night. 3. Strengthen nutrition, eat more blood Qi food, such as donkey hide gelatin, red dates, peanuts, wolfberry, astragalus, angelica, etc. 4. Take a walk, jog and play Tai Chi every day to improve and strengthen the physique and cardiovascular function. 5. In the process of conditioning, you can detect whether your blood pressure is normal, dizziness, dizziness and other symptoms are improved, if necessary, you can carry out drug conditioning.
