Primary outcomePrimary: Change in Mean Pulmonary Artery Pressure (MPAP) — 6.5; 4.3 mmHg
Summary
The purpose of the present pilot study is to test the hypothesis that in patients with group 1 pulmonary arterial hypertension (PAH) who are on regular oral pulmonary vasodilator therapy, inhaled albuterol causes transient pulmonary vasodilation.
