Plain language summary

In this case series study, pulmonary artery systolic, diastolic, and mean pressures of 2 participants with obesity and heart failure with preserved ejection fraction were measured at zero gravity during parabolic flight to assess the effect of external constraint on left ventricular filling pressures.
