Key Finding

We aimed to assess long working hours as a risk factor for incident coronary heart disease and stroke. Cumulative random-effects meta-analysis was used to combine effect estimates from published and unpublished data.

We found that employees who work long hours have a higher risk of stroke than those working standard hours; the association with coronary heart disease is weaker. These findings suggest that more attention should be paid to the management of vascular risk factors in individuals who work long hours.
