In patients with PAH, chronic elevation of pulmonary arterial pressure and vascular resistance result in right ventricular enlargement causing right heart strain. Right ventricular overload leads to progressive remodeling and contractile dysfunction of the right ventricle eventually resulting in the most common and feared complication of PAH, right-sided heart failure.

Other complications of PAH include:

  • Pulmonary artery dissection

  • Massive hemoptysis

  • Left main compression syndrome
