Study population: Adults aged 40 to 80 years with no known history of chronic heart failure (CHF), referred for an outpatient cardiology consultation at participating centers for reasons other than suspected CHF or any of the four EPOF signs. Participants underwent NT-proBNP or BNP measurement as part of routine clinical care, either before or during the cardiology consultation if considered clinically indicated by the treating cardiologist. The study is observational and does not require any additional diagnostic procedures or biomarker testing beyond routine clinical practice.

About this study
This observational study aims to evaluate whether measuring NT-proBNP (or BNP), either on its own or alongside the EPOF questionnaire, can improve the early detection of chronic heart failure (CHF) in adults aged 40 years or over who are referred for an outpatient cardiology evaluation and have no known or suspected CHF.
The study will address the following questions:
Read more
Does systematic NT-proBNP (or BNP) testing help to identify previously unrecognised CHF? Does combining NT-proBNP (or BNP) with the EPOF questionnaire enhance diagnostic accuracy compared with using each tool alone? Participants will attend their routine cardiology consultation, complete the EPOF questionnaire and undergo NT-proBNP (or BNP) testing as part of the clinical assessment. They will also allow the collection of relevant medical data. The diagnostic performance of these tools will then be compared with the final diagnosis made by the outpatient cardiologist.
The study focuses on a population referred from primary care with increased cardiovascular risk. The early use of simple, accessible tools could reduce diagnostic delays, improve referral appropriateness and facilitate the earlier detection of CHF in general practice.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Adults ≥40 years referred for cardiology consultation without suspected chronic heart failure | Adults aged 40 years and older with no history of chronic heart failure (CHF), referred for a cardiology consultation at participating centers for reasons other than suspected CHF, and who underwent NT-proBNP or BNP measurement as part of routine clinical care. The biomarker measurement may have been performed before the consultation or ordered by the treating cardiologist during the consultation if considered clinically indicated, independently of study participation. The study does not require or mandate any additional NT-proBNP or BNP testing; participants are included only if a routine-care biomarker result is available. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sensitivity of the combined EPOF questionnaire and natriuretic peptide strategy for detecting chronic heart failure
Sensitivity (with 95% confidence interval) of the combined screening strategy defined as a positive EPOF questionnaire (EPOF score ≥1) and/or a positive natriuretic peptide result (NT-proBNP ≥125 ng/L or BNP ≥35 ng/L), using the final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up as the reference standard.
Measured: Baseline
Secondary outcomes (6)
Diagnostic performance of the EPOF questionnaire
Diagnostic performance of the EPOF questionnaire and each of its individual components, including sensitivity, specificity, positive predictive value, and negative predictive value with corresponding 95% confidence intervals, using the final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up as the reference standard.
Measured: Baseline
Diagnostic performance of natriuretic peptide measurement
Diagnostic performance of a positive natriuretic peptide result (NT-proBNP ≥125 ng/L or BNP ≥35 ng/L), including sensitivity, specificity, positive predictive value, and negative predictive value with corresponding 95% confidence intervals, using the final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up as the reference standard.
Measured: Baseline
Diagnostic performance of the combined EPOF + NT-proBNP strategy
Diagnostic performance of the combined screening strategy defined as a positive EPOF questionnaire (EPOF score ≥1) and/or a positive NT-proBNP result (≥125 ng/L), including sensitivity, specificity, positive predictive value, and negative predictive value with corresponding 95% confidence intervals, using the final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up as the reference standard.
Measured: Baseline
Diagnostic performance of the combined EPOF + BNP strategy
Diagnostic performance of the combined screening strategy defined as a positive EPOF questionnaire (EPOF score ≥1) and/or a positive BNP result (≥35 ng/L), including sensitivity, specificity, positive predictive value, and negative predictive value with corresponding 95% confidence intervals, using the final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up as the reference standard.
Measured: Baseline
Diagnostic performance in prespecified subgroups
Diagnostic performance of the EPOF questionnaire, natriuretic peptide measurement, and the combined screening strategies in prespecified exploratory subgroups defined by sex (men and women), age (40-59 years and ≥60 years), and body mass index (<30 kg/m² and ≥30 kg/m²). Diagnostic performance measures include sensitivity, specificity, positive predictive value, and negative predictive value with corresponding 95% confidence intervals.
Measured: Baseline
Prevalence of chronic heart failure
Prevalence of chronic heart failure, defined as the proportion of participants with a final diagnosis of chronic heart failure established by the treating cardiologist after completion of the routine diagnostic work-up, reported with the corresponding 95% confidence interval.
Measured: Baseline

Questions about this trial
What is this clinical trial studying?
An observational study of NT-pro-BNP and NT-proBNP, run by French Cardiology Society at 2 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 23 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Barnabas GELLEN, MD (01 44 90 70 28 ext. +33, declic@sfcardio.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sensitivity of the combined EPOF questionnaire and natriuretic peptide strategy for detecting chronic heart failure (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2026.
