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.
