Evaluate The Clinical Effectiveness, Safety And Tolerability Of Sildenafil Used In Doses ?20mg TID For The Treatment Of Pulmonary Arterial Hypertension
The objective of this observational study is to gain clinical insight on the actual use of sildenafil citrate (Revatio?) for the treatment of pulmonary arterial hypertension (PAH). The primary objective is to assess effectiveness and safety of sildenafil at doses ?20mg three times daily for the treatment of PAH.
The study design proposed is a retrospective chart review going back five years (01 April 2006 estimate) from the time of study initiation (31 March 2011 estimate). Within this five-year period, study index will occur the first time an adult patient begins sildenafil for the treatment of PAH for a period of at least three months. The patient has to be taking sildenafil at doses ? 20mg tid for the treatment of PAH.
