Pulmonary hypertension (PH) is prevalent in decompensated heart failure with preserved ejection fraction (HFpEF). We investigated the effect of a return to a compensated state on pulmonary artery systolic pressure (PASP) and functional mitral regurgitation (FMR). ⋯ Noninvasive monitoring of PASP and FMR during an episode of HFpEF decompensation reveals that the return to a compensated state is associated with a significant reduction in PASP and FMR.
