What does pulmonary hypertension lead to in the right ventricle?

Pulmonary hypertension results in increased pressure in the pulmonary arteries, which in turn creates a higher workload for the right ventricle as it struggles to pump blood through the narrowed vessels. This augmented workload can lead to hypertrophy (thickening) of the right ventricle muscle as it adapts to the increased demands. Over time, the right ventricle may become efficient in managing this higher pressure but can eventually lead to right-sided heart failure if the underlying condition is not addressed.

Additionally, the increased pressure in the pulmonary circulation can lead to pulmonary edema, a condition where excess fluid accumulates in the lungs. This is a direct consequence of the increased pressure in the pulmonary vasculature, affecting gas exchange and potentially leading to further complications like decreased oxygenation throughout the body.

Thus, the association of pulmonary hypertension with both increased workload on the right ventricle and the potential for creating fluid build-up in the lungs makes the response regarding increased workload and pulmonary edema the most accurate.
