Introduction and objectives: There are no data on outcome of patients with pulmonary hypertension (PH) in Argentina. The objective of this registry was to assess the characteristics of patients with PH belonging to the Group I Dana Point's 2008 classification, pulmonary arterial hypertension (PAH), and to identify variables associated with outcomes. Methods: One hundred and thirty four patients were analyzed in a consecutive sequence. After excluding nine patients, 125 patients were analyzed. Results: The patients mean age was 34 years (SD±15,7) and the female/male ratio was 3.8/1. The most prevalent aetiologies were: idiopathic PAH (IHAP) (61, 48.8%), PH associated to congenital heart disease (35, 28%) and PH associated to connective tissue disease (18, 14.4%). Overall survival, excluding transplantation, was 63.2%; at 12, 24 and 36 months survival was 94% (CI 95% 88-97), 90% (CI 95% 83-94) and 83% (CI 75-89), respectively. Baseline variables associated to increased mortality or need for transplantation were functional class III/IV (NYHA) (OR 3.6 CI 95% 1.5-8.9, p <0.01), 6 minute-walk test distance shorter than 380 m (OR 2.7 CI 95% 1.1-6.5 p = 0.023) and pericardial effusion (OR 4.2 CI 95% 1.3-14.6 p = 0.021). Conclusion: This series shows characteristics and survival of patients with pulmonary arterial hypertension at a reference centre in Argentina. Some readily available variables allowed us to stratify subgroups at a higher risk of death and/or transplantation during the follow up.
