Which condition could possibly be present in a patient with elevated CVP and normal PAP?

In the scenario of elevated central venous pressure (CVP) with normal pulmonary artery pressure (PAP), the most appropriate condition to consider is cor pulmonale, which refers to right heart failure due to increased pressure in the pulmonary circulation stemming from pulmonary issues.

Elevated CVP indicates that there is increased pressure in the right atrium and might suggest volume overload, right ventricular dysfunction, or venous obstruction. However, normal PAP suggests that the pulmonary arteries themselves are not experiencing elevated pressure, which is typically expected in various pulmonary conditions affecting pressure.

In cor pulmonale, the right ventricle becomes compromised due to the increased workload from issues like chronic lung disease, which can cause pulmonary vasoconstriction and ultimately lead to right ventricular failure without necessarily elevating the PAP if the overload is primarily volume-related or due to intrinsic right ventricular issues.

The other options, while pertaining to heart and lung conditions, do not fully align with the specific clinical profile of elevated CVP and normal PAP. For instance, pulmonary embolism generally leads to increased PAP due to obstruction in the pulmonary circulation. Fluid overload might elevate CVP, but typically, it would also cause elevated PAP if severe. Mitral valve stenosis typically affects the left side of the heart,
