Could a simple blood test catch lung hypertension early?
NCT ID NCT04193046
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study looked for specific molecules in the blood (called microRNAs) that could help detect pulmonary hypertension (PH) early. Researchers analyzed blood samples from 907 participants who had or were scheduled for a right heart catheterization, the standard diagnostic test. The goal was to see if a blood test could identify PH as accurately as current methods like echocardiograms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple blood test for early detection of pulmonary hypertension, allowing for earlier treatment.
- What could go wrong
- This is an early-phase study focused on identifying biomarkers, not testing a treatment. The biomarkers may not prove accurate enough for widespread use.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Having undergone an right heart catheterization (RHC) within 18 months (prevalent PH participants) or 6 months (prevalent non-PH participants) or have undergone or planned RHC within 6 weeks (incident participants). The results of the incident RHC (incident participants) or the most recent RHC (prevalent participants) will be used to classify the participant in one of the above study population categories * 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 provide an Informed Consent Form (ICF) (or their legally acceptable representative must sign) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to participate in the study * Must provide a separate informed consent (or their legally-acceptable representative must sign) if he or she agrees to provide an optional (deoxyribonucleic acid \[DNA\]) sample for research (where local regulations permit). Refusal to give consent for the optional (DNA) research sample does not exclude a participant from participation in the study Exclusion Criteria: * Participants requiring renal dialysis * History of lung or heart transplant (waiting list status or consideration of enlisting is allowed) * Severe left ventricular dysfunction: Left ventricular ejection function less then (\<) 35 percent (%)
