If the left ventricle undergoes failure, the blood will eventually back up into the pulmonary circulation; this raises pulmonary vascular pressure. Since blood from the right side of the heart (right ventricle) cannot flow into the left side of the heart (left ventricle), it will also back up into the systemic circulation. This leads to congestion and fluid accumulation in various parts of the body. What is the consequence of left ventricle failure?
1) Increased pulmonary vascular pressure
2) Decreased pulmonary vascular pressure
3) Increased systemic vascular pressure
4) Decreased systemic vascular pressure
