[Pulmonary arterial hypertension--experience of Centro Hospitalar de Vila Nova de Gaia].
BACKGROUND
Pulmonary arterial hypertension (PAH) is a serious and progressive disease, potentially fatal in a few years. Until the 1990s the only effective treatment for this disease was pulmonary/cardiopulmonary transplant. Over the last few years several drugs have emerged that have modified the course of the disease.


OBJECTIVE
To characterise patients with PAH followed at Centro Hospitalar de V.N.Gaia between 2000 and 2006. To raise awareness of this entity.


METHODS
Retrospective analysis of all patients with PAH or chronic thromboembolic pulmonary hypertension (CTEPH) followed at our Hospital.


RESULTS
In this period 11 patients were observed, 7 women and 4 men, with a mean age of 43 y. Five patients had idiopathic PAH, three had CTEPH, two had PAH associated with interauricular communication and one had PAH associated with CREST Syndrome. At the time of diagnosis most patients were in NYHA/ /WHO Functional Class III/IV, mean systolic pulmonary artery pressure was 98+/-32 mm Hg and mean distance walked in the 6-minute walk test was 401 m. Initial treatment: Three patients had inhaled iloprost, two subcutaneous treprostinil, three oral bosentan, one oral sildenafil and two patients under- went surgery. Mean follow-up time was 28.1 months. Five patients recovered, three are stable, one worsened and two died.


CONCLUSIONS
PAH is a serious illness which requires a multidisciplinary approach with the need for complex and expensive therapies. Diagnosis in initial sta- ges is essential for an effective treatment.
