Extreme Temperature Events, Fine Particulate Matter, and Myocardial Infarction Mortality

Abstract

This study provides consistent evidence that exposure to both ETEs and PM_2.5 is significantly associated with an increased odds of MI mortality, especially for women and older adults, and that heat wave interacts synergistically with PM_2.5 to trigger MI deaths but cold spell does not. Our findings suggest that mitigating both ETE and PM_2.5 exposures may bring health cobenefits in preventing premature deaths from MI.
