Association of healthy sleep patterns with incident sudden cardiac arrest: a prospective study of 414,625 UK biobank participants

Over a median follow-up of 13.93 years, 2545 incident sudden cardiac arrest cases were identified among 414,625 participants.

• Participants with sleep scores of 4 or 5 had a 19% lower risk of sudden cardiac arrest compared to those with scores of 0-1.
• Each one-point increase in sleep score was associated with a 5% reduction in the risk of sudden cardiac arrest.
• A dose-response relationship was observed between sleep scores and sudden cardiac arrest risk, with no evidence of nonlinearity.
• If all individuals achieved an optimal sleep score of 5, the incidence of sudden cardiac arrest may potentially be reduced by 17.11%.
• The association between sleep scores and sudden cardiac arrest risk was more pronounced in individuals younger than 60 years and those without chronic conditions.
