What hemodynamic change is typically seen in patients with right heart failure?

In patients with right heart failure, an important hemodynamic change observed is an increased central venous pressure (CVP). Right heart failure occurs when the right ventricle is unable to effectively pump blood into the pulmonary circulation, often leading to congestion in the systemic venous circulation. This increased pressure in the venous system is reflected by a higher CVP, as it indicates that blood is backing up into the veins leading to the right atrium.

This state of elevated CVP can result in symptoms such as peripheral edema, ascites, and jugular venous distension due to the fluid overload in the venous system. Monitoring CVP is valuable in assessing the hemodynamic status of patients, particularly in those with right heart dysfunction, as it provides insight into the filling pressures of the heart and the effectiveness of venous return.

While factors such as decreased cardiac output (CO) might also be present in right heart failure, the key indicator specifically tied to the dysfunction of the right heart is the increased CVP. This aspect highlights the interplay between right ventricular function and systemic venous return.
