Why does right heart failure cause systemic circulation congestion

Right heart failure refers to right heart failure. The causes of systemic congestion caused by right heart failure include weakened cardiac pumping function, physiological structure and increased local pressure. The specific analysis is as follows:

1. Physiological structure

Because the right atrium belongs to the end point of systemic venous blood return, if heart failure occurs, it will lead to venous blood return disorder of the body, which is easy to cause systemic congestion.

2. Weak cardiac pumping function

Because right heart failure leads to weakened cardiac pumping function, resulting in delayed blood supply of the body, resulting in systemic congestion.

3. Increased local pressure

Due to right heart failure, a large amount of cardiac blood is deposited in the right atrium, resulting in increased pressure in the right atrium, resulting in reduced return blood volume, inducing systemic congestion.
