Association of Life’s Essential 8 and incident cardiac conduction disorder: a prospective cohort study
Main finding · Incident CCDResult — go to the resultHazard ratio 0.48 95% CI 0.40–0.56Authors' conclusion
Higher LE8 scores were associated with a lower risk of CCD, including severe conduction block requiring pacemaker implantation and left bundle branch or fascicular block.

Individual LE8 metrics (WQS analysis)
- BMI and sleep health were the major contributors to reduced CCD risk
