Link between sleep problems found with a brief questionnaire and heart disease

Assessment of the Association Between Sleep Disorders Detected by a Simplified Questionnaire and Cardiovascular Diseases: a Prospective Study in Cardiology Consultations

Observational French Cardiology Society · NCT07432828

This project tests whether a short questionnaire used during cardiology visits can quickly find sleep problems related to cardiovascular disease in adult cardiology patients.

What this trial studies

This is a prospective, multicenter, national observational registry that uses a patient-facing online questionnaire to detect sleep disorders during cardiology consultations and a separate survey for participating cardiologists to document practice change. Adult cardiology patients who can complete the questionnaire and are not on active treatment for severe sleep disorders are enrolled at participating French cardiology centers. The study collects responses centrally to validate the simplified screening tool and to describe associations between identified sleep problems and cardiovascular conditions. Cardiologists also complete a brief impact survey to record whether the tool changes screening or referral behavior in routine practice.

Who should consider this trial

Good fit: Adults (≥18 years) seen in cardiology who can complete an online questionnaire and who are not currently receiving active treatment for a severe sleep disorder are ideal candidates.

Not a fit: Patients already on active treatment for severe sleep disorders (for example CPAP, oral appliance, treated narcolepsy, or pharmacologically treated chronic insomnia) or those unable to complete the questionnaire are unlikely to benefit from this screening tool.

Why it matters

Potential benefit: If successful, the tool could help cardiologists quickly spot untreated sleep disorders that contribute to heart disease and lead to earlier referrals or treatment.

How similar studies have performed: Other screening tools like STOP‑Bang and the Epworth Sleepiness Scale have shown moderate success detecting sleep apnea, but simplified questionnaires specifically validated for routine cardiology visits are less well established.
