About

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.
