A recent study led by Harvard T.H. Chan School of Public Health suggests that prolonged exposure to fine particulate air pollutants (PM2.5) could heighten the likelihood of seniors being hospitalized for various cardiovascular ailments.
Objective To estimate exposure-response associations between chronic exposure to fine particulate matter (PM2.5) and risks of the first hospital admission for major cardiovascular disease (CVD) subtypes. Design Population based cohort study. Setting Contiguous US. Participants 59 761 494 Medicare fee-for-service beneficiaries aged ≥65 years during 2000-16. Calibrated PM2.5 predictions were linked to each participant’s residential zip code as proxy exposure measurements. Main outcome measures Risk of the first hospital admission during follow-up for ischemic heart disease, cerebrovascul...
Chronic exposure to fine particulate air pollutants (PM2.5) may increase seniors' risk of hospitalization for a variety of cardiovascular conditions, according to a new study led by Harvard T.H. Chan School of Public Health.
<ul> <li>Chronic exposure to fine particulate air pollutants (PM2.5) may increase seniors’ risk of cardiovascular hospitalization, with disproportionate impacts on residents of socioeconomically deprived neighborhoods.</li> <li>The findings suggest that to protect heart health, there is no safe threshold for chronic PM2.5 exposure, and that the EPA’s newly updated standard for the U.S.’s annual average PM2.5 level isn’t low enough to reduce the burden of cardiovascular disease or protect public health overall.</li> </ul...
