Historically the prognosis for patients with untreated<unk>  was poor, with a 5-year survival of 40 mmHg at presentation. More contemporary data from the European<unk>  registry have demonstrated a 70% 3-year survival in patients with<unk>  who do not undergo the surgical procedure of pulmonary endarterectomy (PEA). Recent data from an international<unk>  registry demonstrate that mortality in<unk>  is associated with New York Heart Association (NYHA) functional class IV, increased right atrial pressure, and a history of cancer. Furthermore, comorbidities such as coronary disease, left heart failure, and<unk>  obstructive pulmonary disease (COPD) are risk factors for mortality.
