Heart disease and stroke are the first and fifth leading causes of death in the United States, respectively. Employers have a unique opportunity to promote cardiovascular health, because >60% of US adults are employed, and most spend half of their waking hours at work. Despite the scope of the opportunity, <1 in 5 businesses implement evidence-based, comprehensive workplace health programs, policies, and practices. Integrated, systems-based workplace health approaches that harness data science and technology may have the potential to reach more employees and be cost-effective for employers. To evaluate the role of the workplace in promoting cardiovascular health across the lifespan, the National Heart, Lung, and Blood Institute, the National Institute for Occupational Safety and Health, and the American Heart Association convened a workshop on March 7, 2019, to share best practices, and to discuss current evidence and knowledge gaps, practical application, and dissemination of the evidence, and the need for innovation in workplace health research and practice. This report presents the broad themes discussed at the workshop and considerations for promoting worker cardiovascular health, including opportunities for future research.
