Therefore, it is essential to describe the clinical characteristics and outcomes associated with prostanoid treatment in this population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study involved patients with PH\u20101. Hemodynamic and clinical variables were compared before the initiation of prostanoids and during clinical follow\u2010up. Overall survival was analyzed using Kaplan\u2013Meier estimation, with survival rates calculated at 3 and 5 years.

Idiopathic pulmonary arterial hypertension was present in 62%, and 60% were classified as intermediate risk at baseline. Median time from PH\u20101 diagnosis to prostacyclin initiation was 8.96 months (IQR 1.88\u201341.42). At 1 year, complete follow\u2010up data were available for 49 patients.
