A Study for the Identification of Biomarker Signatures for Diagnosis of Pulmonary Hypertension (PH) in Participants at Low or Intermediate Probability of PH Undergoing Cardiac Magnetic Resonance Imaging

Inclusion Criteria

• •Referred for diagnostic work-up for pulmonary hypertension (PH)
• •With low or intermediate (but not high) probability of PH by transthoracic echocardiography (TTE) according to European Society of Cardiology (ESC)/ European Respiratory Society (ERS) Guidelines if at the time of enrollment Right Heart Catheterization (RHC) is not deemed to be clinically indicated
• •Medically stable on the basis of physical examination, medical history and vital signs performed at screening. Any abnormalities must be consistent with the underlying illness in the study population and this determination must be recorded in the participant's source documents and initialed by the investigator
• •Must sign an Informed consent (ICF) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to participate in the study
• •Must sign a separate approval in the ICF if he or she agrees to provide an optional (DNA) sample for research. Refusal to give consent for the optional (DNA) research sample does not exclude a participant from participation in the study
