Dynamic nature of pulmonary artery systolic pressure in decompensated heart failure with preserved ejection fraction: role of functional mitral regurgitation.

BACKGROUND 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). METHODS AND RESULTS Two-dimensional Doppler echocardiography was prospectively… CONTINUE READING
