Weakness and failure of the left ventricle

Weakness and failure of the left ventricular lead to stagnation of blood pressure increases 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 fills hard. Moreover, if his performance is not much reduced, it can increase your cardiac output to normal, so that balance is restored to the normal circulation to the systemic circulation, but high blood pressure in the small. When the left ventricle and the evils of this first stage of hypertension 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 faster than exhausted the reserve forces and compensatory factors of the right heart, the greater 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 right ventricular failure, liver, blood vessels and other organs that are closer to the heart, the first overflow venous blood. They have deposited some of the blood. Especially crowded blood liver depositing about 1.5 liters of blood (the 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.
