(A,B) Kaplan–Meier survival curves demonstrate prognostic relevance of both invasive and non-invasive pulmonary capillary wedge pressure. (C) Cardiac magnetic resonance-derived pulmonary capillary wedge pressure was non-inferior to an invasively measured pulmonary capillary wedge pressure. (D) After adjusting for all cardiac magnetic resonance variables associated with mortality, cardiac magnetic resonance-modelled pulmonary capillary wedge pressure independently predicted outcomes. (E,F) In the validation cohort, the transthoracic echocardiography and cardiac magnetic resonance models both independently predicted outcomes. Early outcomes were better predicted with the cardiac magnetic resonance model.
