Comparisons of rest and exercise echocardiographic and expired gas parameters between participants with and without exercise lung water. Participants with exercise EVLW from rest to the recovery period showed (A) lower LA reservoir strain at rest, (B and C) a higher E/e′ ratio and estimated pulmonary artery systolic pressure (ePASP), (D) lower systolic tissue velocities at the lateral tricuspid annulus (TV s′), (E) a TAPSE to PASP ratio, and (F) an elevated minute ventilation to carbon dioxide production (V_E vs. VCO₂) slope during peak exercise compared with those without.
