Values are mean±SD or median (IQR). p Values reflect comparison of change between ODD+ and ODD− groups.
DAO, descending aorta; EDP, end-diastolic pressure; ODD, occult diastolic dysfunction; PCWP, pulmonary capillary wedge pressure; PVRi, pulmonary vascular resistance indexed to body surface area; SaO2, oxygen saturation; SVC, superior vena cava; TPG, transpulmonary gradient.
