Causes

• obstructive sleep apnea does not cause sufficiently elevated pulmonary pressures to cause PAH

Diagnosis

• In primary pulmonary hypertension the pulmonary artery diastolic pressure is much higher than the pulmonary capillary wedge pressure.
• If the pulmonary hypertension is due to left-sided heart failure, and the pulmonary artery diastolic pressure in the pulmonary capillary wedge pressure will be similar.
