Higher County-Level Radon Concentrations Linked to Heart Failure in Postmenopausal Women
In a prospective cohort of 43,188 postmenopausal women, county-level indoor radon concentrations above 4 pCi/L were associated with higher incidence of heart failure than concentrations below 2 pCi/L. The observational findings do not establish that radon exposure caused heart failure.
- Cohort included 43,188 postmenopausal women
- Mean follow-up was 16.2 years
- Radon above 4 pCi/L was associated with higher heart failure risk
- Exposure was assigned at the county level
Researchers analyzed data from 43,188 postmenopausal women in the Women’s Health Initiative observational study and clinical trials. Participants were aged 50 to 79 years and had no self-reported heart failure at enrollment or randomization. County-level radon concentrations were assigned using geocoded addresses and categorized as below 2, 2 to 4, or above 4 pCi/L. Incident hospitalization for acute decompensated heart failure was physician-adjudicated during follow-up.
