[Treatment of pulmonary artery hypertensions]

The pulmonary hypertension (PAH) in chronic obstructive lung disease include therapy of the respiratory disease i.e. bronchodilator, kinesitherapy. Long-term oxygen therapy (more than 15 h/day) reverse the course of PAH and increase survey. Long-term efficiency of vasodilators is not well demonstrated. Primary PAH could benefit from vasodilators, especially waiting lung or heart-lung transplantation. Patients with PAH secondary to respiratory insufficiency could also be successfully transplanted. In post embolic PAH, antithrombotic agents are useful. Thrombectomy or transplantation are sometimes proposed.
