Frontal Chest X-Ray images from 2 Study Population subjects represent the PVPs of both forms of cardiopulmonary-derived Pre-Capillary PH, including: CpcPH: Main and central pulmonary artery dilatation superimposed on PVH (Stage 2-Late in this case) (A). Group 1 PH: Main and central pulmonary artery dilatation without PVH, lung disease, etc. (B). CpcPH : Combined pre-/post-capillary Pulmonary hypertension PH: Pulmonary Hypertension, PVH: Pulmonary Venous Hypertension, PVP: Pulmonary Vasculature Pattern.
