Weakness and failure of the left ventricle leads to stagnation of blood pressure increases in the left atrium and the pulmonary circulation. Under the influence of high pressure in the pulmonary and left atrium during diastole the left ventricle fills hard. Moreover, if his performance is not much reduced, it can increase your minute volume to normal, so that a balance is reached with normal blood circulation in the systemic circulation, but high blood pressure in the small. When the evils of the left ventricle and hypertension, this first stage of heart failure, and at the same time and compensation can be kept for a long time and lead to hypertrophy and tonogennomu expansion of the right ventricle. The further held that state faster exhausted the reserve forces and compensatory factors right heart, the more noticeable developing venous hypertension in the systemic circulation, liver congestion, abdominal organs, edema in the lower extremities, ascites and all the other consequences.
When it comes right ventricular failure, liver, blood vessels and other organs that are closer to the heart, the first overflow of venous blood. They shall be part of the blood. Especially liver blood overflow, deposited about 1.5 liters of blood (hepatic veins have no valves, and thus do not impede venous backflow of blood to the liver). Rev. these phenomena are of great importance in compensatory heart failure.
- Venous blood of the left ventricle
According to new data in the literature, the venous blood of the left ventricle flows mainly through the coronary sinus, really - on the smallest veins. There is every reason to believe that the different functional states, primarily under the influence of pressure changes in different chambers of the heart, and in the different segments of the coronary circulation, blood flow in the vessels Vessena-Tebeziya can [...]
- Effective treatment of patients with essential hypertension resort factors Turshsu
We set out to study the effectiveness of the treatment of patients suffering from hypertension, various complexes of therapeutic factors Turshsu. To do this, studied the effectiveness of: 1) a medical complex - Climate + mineral water "Turshsu" inside and 2) a separate bath and turshsuinskoy medical complex - Climate + mineral water "Turshsu" inside + course turshsuinskih baths. Certainly, the elucidation of these issues has [...]
- Communication between authorities
It should be noted that among all the bodies that release certain hormones, there is a mutual relationship. Because of this connection, some cancer have an impact on other products of these glands are allocated in proportion to the need of the organism and are actively involved in regulatory mechanisms. Thus, there is no doubt impact on pituitary adrenal and other glands, and is not excluded [...]
- Definition of peripheral vascular tone
Peripheral vascular tone is determined ostsillografichsskim and plethysmographic methods. As is known, blood pressure is the pressure that blood tests, located in the arterial network. Hence it is clear that the state of the arterial network, its filled with blood, the impact of various external and internal factors on the walls of blood vessels and blood allow at any given period of time to maintain optimal blood pressure, that is. [...]
- Disruption of the neurohumoral
Disruption of the neurohumoral regulating mechanisms of blood pressure can lead to hypotension or hypertension, and ultimately - to hypertension. If under the influence of nervous factors primarily arise increase vascular tone, for the further development of hypertension requires a number of additional factors. For the development of hypertension are needed, along with impaired cortical dynamics changes in the [...]
