For each patient with Heart Failure and Pulmonary Hypertension (with preserved (HFpEF) or reduced (HFrEF) ejection fraction), the median (center dot) and interquartile range (vertical line) for the percent medial thickness (% MT, arteries) and % intimal thickness (%IT, arteries, veins and indeterminate vessels (IV)) in all vessels analyzed in each patient are shown. Similar data are shown in comparator groups (Controls and Pulmonary Veno-occlusive Disease, PVOD).
