The goal of this observational study is to validate a simplified questionnaire, adapted for routine clinical use, to quickly detect sleep disorders in patient during a cardiology consultation.

Two questionnaires were developed for this project. The first is patient-oriented: a prospective, multicentre, national observational registry based on a patient questionnaire designed to quickly detect sleep disorders during a cardiology consultation.

The second is aimed at treating cardiologists: this is a simple impact survey designed to assess changes in the practices of cardiologists who participated in CARDIOSOM.

Inclusion Criteria - Patient :

• Adult patients (≥18 years old) consulting in cardiology.
• Ability to complete the questionnaire.
• No objection

Inclusion Criteria - Cardiologist:

Cardiologists who participated in CARDIOSOM and who conduct cardiology consultations that include a systematic or non-systematic assessment of their patients' sleep quality (duration, regularity, insomnia, sleepiness, suspected obstructive sleep apnea (OSA)) and whether or not suspected sleep disorders in patients are treated.

Exclusion Criteria - Patient :

• Active treatment for a severe sleep disorder (severe sleep apnea under CPAP (Continuous Positive Airway Pressure) or orthotic device, narcolepsy, chronic insomnia being treated)
• Refusal to participate
