Identification of Pulmonary Arterial Hypertension Patients with Venous or Capillary Involvement

The authors aimed to develop a likelihood score to distinguish patients with pulmonary arterial hypertension (PAH) who have features of venous or capillary involvement (PVOD/PCH) from those with other forms of PAH. By analyzing clinical variables from existing literature, they created a score that demonstrated high accuracy in identifying PVOD/PCH, which could improve early diagnosis, management, and expedite lung transplant referrals for affected patients.
