NCT04101630

Brief Summary

This is a prospective, longitudinal, observational study of free-living activity trackers and patient reported outcomes to test the hypothesis that daily activity will have stronger prognostic value than 6MWD in patients with pulmonary hypertension after 12 weeks.

Study Arms (2)

Participants with Pulmonary Hypertension

Participants will undergo activity monitoring for 12 weeks, at baseline and once a year for 3 years. Patient reported outcomes will be collected including Quality of Life questionnaires \[emphasis-10, Minnesota Living with Heart Failure (MLHF), and SF-36 surveys\], medication changes, hospitalization, and death.

Behavioral: Activity Monitoring

Healthy Volunteers

Participants will undergo activity monitoring for 12 weeks, at baseline and once a year for 3 years. Patient reported outcomes will be collected including Quality of Life questionnaires \[emphasis-10, Minnesota Living with Heart Failure (MLHF), and SF-36 surveys\], medication changes, hospitalization, and death.

Study Population

Participants will be those enrolled in the Longitudinal Pulmonary Vascular Disease Phenomics Program (L-PVDOMICS) and any patient with pulmonary hypertension.

You may qualify if:

  • Enrolled in L-PVDOMICS or
  • Any patient in the United States with pulmonary hypertension confirmed by hemodynamics and expert clinical diagnosis

You may not qualify if:

  • Pregnancy
  • Hospitalization within the prior 3 months

Data Sharing

IPD Sharing
Will share

Use of study data and biospecimens, and resulting findings, during the PVDOMICS study are subject to approval of the PVDOMICS Steering Committee and follow guidelines of the Publications and Ancillary Study Committee. The data and biospecimens from subjects at a clinical center are the property of the PVDOMICS study and are under the custody of that center. At the end of the PVDOMICS study and this proposal, the data and remaining biospecimens will be transferred to PVDOMICS and/or to the National Heart, Lung and Blood Institute (NHLBI) Biological Specimen and Data Repository Information Coordinating Center (BioLINCC) biobank and become the property of one of these organizations. Future researchers may request data or biospecimens from a biobank with approval following the guidelines of the biobank. Protocols for data sharing after the conclusion of PVDOMICS have not been established, but will be created in accordance with the NIH Data Sharing Policy.
