Design outcomes

Primary

Measure	Time frame
1. CAB values relating to S2 characteristics measured at the 3L position, and PAP values (peak value during exercise) measured at each of the following points in provocative testing during right heart catheterization: baseline (at rest), exercise (provocation), cool-down (at rest). 2. CAB values measured at the Apex and 3L positions, and PAP values and hemodynamic indicators other than PAP (PCWP, CO, etc.) measured at each of the following points in provocative testing during right heart catheterization: baseline (at rest), exercise (provocation), cool-down (at rest).	—
