Blood pressure in various diseases

Since blood pressure is determined by many factors, it is subject to change at various diseases. Pathological reduction in blood pressure is called arterial hypotension, increase of arterial hypertension. Arterial hypotension observed with intoksikatziah (poisoning, infectious diseases), severe heart disease (myocardial infarction), primary violation of the nervous regulation of vascular tone (hypotonic option neuro-circulatory dystonia), some endocrine diseases (e.g., Addison's disease). Causes of hypertension more diverse. Most often it is a manifestation of a kind of vasomotor neurosis - hypertensive disease (see). Unlike hypertension, all other forms of high blood pressure is called symptomatic hypertension syndrome. The so-called hemodynamic hypertension caused by the loss of elasticity of the arterial walls (for example, due to atherosclerosis) or congenital narrowing of the aorta below the place of discharge of large arteries of the head and shoulder girdle (coarctation of the aorta). In the latter case, the blood pressure in the brachial artery high, and in the arteries of the legs sharply reduced. Hypertension is observed in many endocrine diseases (disease Itsenko-Cushing syndrome, pheochromocytoma, pathological menopause and others). Often hypertension caused kidney damage in nephritis, pyelonephritis or the narrowing of the renal artery. Hypertension, developing at the primary defeat of renal tissue, called renal or kidney, hypertension, caused by the narrowing of the renal artery - renovaskulyarnoy.
Given the diversity of causes of hypertension, should in all cases to try to identify the disease, the underlying increase blood pressure. It is the underlying disease (jade, feohromotsytoma, coarctation of aorta, and so on) and determines the peculiarities of each patient. If a radical treatment of the cause of hypertension is impossible (for example, surgical removal of pheochromocytoma or the excision of pyelonephritis, kidney), a therapy as well as in hypertensive disease (see).
