Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Determine whether the WTT app on the Apple Watch can accurately collect information on distance traveled and heart rate (HR) during in-clinic 6MWT run by American Thoracic Society (ATS) guidelines
* Determine whether participants can operate the WTT app and Apple Watch effectively to gather accurate data in a monitored and home-based setting
* Prospectively monitor for changes in WTT app recorded 6MWT results following initiation of therapy in a treatment naïve cohort of PAH participants
* Evaluate whether changes from baseline in 6 minute walk distance (6MWD) and heart rate recovery at one minute (HRR1) as well as other variables that have been associated with disease severity in PAH and left-sided heart disease (resting HR, heart rate variability \[HRV\], chronotropic index \[CI\]) can be identified before the 12-week follow up when comparing the treatment arm and the control arm
* Evaluate whether changes from baseline in the HRR1, resting HR, HRV and/or CI are more evident in treatment responders when compared to treatment non-responders.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Initiating a new PAH medication
Participants will start a new PAH medication
Home-based 6 minute walk test
Participants will receive a loaner Apple Watch with the Walk.Talk.Track. (WTT, produced by PHaware) app downloaded. Participants will perform a daily 6MWT at home using the Apple Watch and WTT app. They will undergo a history and physical, blood draw, echocardiogram and in-clinic 6MWT at the baseline and 12-week follow up visit.
Continuing previous PAH medication regimen
Participants will continue the medication regimen that they were on prior to enrollment
Home-based 6 minute walk test
Participants will receive a loaner Apple Watch with the Walk.Talk.Track. (WTT, produced by PHaware) app downloaded. Participants will perform a daily 6MWT at home using the Apple Watch and WTT app. They will undergo a history and physical, blood draw, echocardiogram and in-clinic 6MWT at the baseline and 12-week follow up visit.
