She has studied Applied Biology at Universidade do Minho and was a postdoctoral research fellow at Instituto de Medicina Molecular in Lisbon, Portugal. Primary pulmonary hypertension is also characterized by endothelial cell proliferation. Due to this capacity, pulmonary hypertension gets worse, which is exacerbated by a decrease in tissue plasminogen activator activity that occurs as consequence of platelet dysfunction, plasminogen activator inhibitor type 1 and fibrinopeptide A high activity and thrombotic coagulopathy. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Despite these targeted therapies, PAH is still associated with significant morbidity and mortality. This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries. Ter Arkh.
