Primary purpose: TREATMENT

Brief summary: This study is looking to see if giving ranolazine to subjects on stable pulmonary hypertension specific therapies but with right ventricular dysfunction (RVEF \<45%) would improve their outcome. This study is accompanied by a baseline comparison of the metabolic profiling/microRNA/iPS cells of subjects with and without right ventricular dysfunction.


Eligibility criteria: Inclusion Criteria:

* Symptomatic pulmonary hypertension based on one of the following criteria: Idiopathic pulmonary arterial hypertension, Familial pulmonary arterial hypertension, pulmonary hypertension associated with connective tissue disease, chronic thromboembolic pulmonary hypertension-nonsurgical/distal vessel disease or patients who are reluctant to go to surgery within a 6-month period and are willing to participate, simple congenital such as repaired atrial septal defect or ventricular septal defect or unrepaired small atrial septal defect or ventricular septal defect with persistent and out of proportion pulmonary arterial hypertension, group 3 patients who have a component of pulmonary arterial hypertension, pulmonary arterial hypertension caused by conditions affect the veins and small vessels of the lungs, sickle cell disease, group 5 pulmonary hypertension such as polycythemia vera, essential thrombocythemia, sarcoidosis, or vasculitis, or metabolic disorder.
