Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Age ≥ 18 years' old
- Be on the lung transplant waiting list at Duke University Medical Center.
- PH as defined by RHC - mPAP > 20 mmHg, PVR > 3 WU, PCWP < 15 mmHg
Groups defined as:
PAH: Clinical diagnosis of PAH (Group 1 PH) in the absence of severe chronic lung disease, left heart disease, chronic thromboembolism, sarcoidosis, sickle cell disease, or other causes of non-Group 1 PH.
COPD-noPH: Clinical diagnosis of COPD in the absence of precapillary PH.
COPD-PH: Clinical diagnosis of COPD with precapillary PH.
IPF-noPH: Clinical diagnosis of IPF in the absence of precapillary PH.
IPF-PH: Clinical diagnosis of IPF with precapillary PH.
- Willing and able to give informed consent and adhere to visit/protocol schedules (consent must be given before any study procedures are performed).
Exclusion Criteria:
- Moderate to severe heart disease (LVEF < 45% or severe LV Hypertrophy).
- Sarcoidosis.
- Active cancer.
- Sickle cell anemia.
- Liver disease (Childs-Pugh class C).
- Prisoners and pregnant women will not be approached for the study.
- Inability to obtain consent.
- Conditions that will prohibit MRI scanning (metal in eye, claustrophobia, inability to lie supine).
- Medical or psychological conditions which, in the opinion of the investigator, might create undue risk to the subject or interfere with the subject's ability to comply with the protocol requirements

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
a pathology-based 129Xe MRI noninvasive signature of pulmonary vascular remodeling that could be validated in a larger cohort of Group 3 PH patients
Time Frame: 2 yrs
|
Such a signature could then be tested in clinical trials in Group 3 PH.
These studies will have an important positive impact because they lay the foundation for a precision medicine strategy in Group 3 PH through the identification of potential responders and non-responders to PAH-specific therapies
