Association Between Sleep Duration and Angina Characteristics in United States Adults

Our findings suggest that sleeping over 8 hours increases the likelihood of Grade 2 angina, while under 7 hours is linked to atypical presentations, complicating diagnosis. Clinicians could incorporate brief sleep assessments-asking about duration and quality-alongside angina tools like the ROSE questionnaire to identify potential sleep-related factors. While promising, these associations require further research before being translated into definitive clinical guidelines for angina management.
