What are the most common causes of death in people with pulmonary arterial hypertension?

Right heart failure is the most common cause of death in people with PAH. Studies show that 44 to 73 percent of PAH deaths are due to right heart failure or cardiac arrest (sudden loss of heart function).

This happens because the narrowed blood vessels in the lungs create high blood pressure, forcing the heart's right ventricle to work much harder to pump blood. Over time, the heart muscle weakens from this extra effort, eventually leading to right ventricular failure.

Other common causes of death in end-stage PAH include:
* Sudden death
* Noncardiac causes
* Complications affecting other organs like the kidneys or liver

As PAH progresses, it can affect multiple body systems beyond just the heart and lungs, which is why regular monitoring by your healthcare team is so important for managing the condition.
