Nationwide potential causal long-term effects of PM2.5 component mixture on ischemic heart disease mortality in the United States, 2000–2019

Key Points

The research aims to explore the causal relationships between PM2.5 component mixtures and ischemic heart disease mortality.
National-level assessment from 2000 to 2019
Analysis of PM2.5 components and their impact on mortality
Focus on vulnerable subpopulations
Identified stronger associations between PM2.5 components and IHD mortality in vulnerable groups.
Highlighted sulfate and nitrate as critical components influencing mortality.

Abstract

This study provides potential causal links for the joint effects of PM2.5 component mixtures on IHD mortality, with stronger associations among vulnerable subpopulations, and identifies sulfate and nitrate as critical components. These findings underscore the necessity of emission controls targeting toxic constituents alongside public health strategies designed to protect susceptible populations.
