Weakness and failure of the left ventricle

Weakness and failure of the left ventricular lead to stagnation of blood with increasing pressure in the left atrium and the pulmonary circulation. Under the influence of high pressure in a small circle and the left atrium during diastole the left ventricle is filled with hard. Moreover, if it is reduced performance is not strong, it can increase your cardiac output to normal, so that a balance is reached with the 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 heart failure, and at the same time and payment can be kept for a long time and lead to hypertrophy and tonogennomu expansion of the right ventricle. The further held that state sooner exhausted the reserve forces and compensatory factors of the right heart, the more noticeable develop venous hypertension in the systemic circulation, congestion of the liver, abdominal organs, swelling of the lower extremities, ascites, and all other consequences.

When it is failure of the right ventricle, 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 crowded blood liver deposited about 1.5 liters of blood (hepatic veins have no valves, and thus they do not prevent backflow of venous blood into the liver). Ver these phenomena are of great importance in compensatory heart failure.
