Components of particulate matter as potential risk factors for acute myocardial infarction.

ABSTRACT:

Background

Particulate matter with an aerodynamic diameter of ≤2.5 µm (PM_2.5) is a heterogeneous mixture, and specific substances that affect cardiovascular events remain unknown. We aimed to examine the association of short-term exposure to PM_2.5 and its components with hospital admissions for acute myocardial infarction (AMI).

Methods

The concentrations of total PM_2.5 and its individual components were continuously measured using Aerosol Chemical Speciation Analysers. From a national-scale administrative database collected from 828 facilities in 47 prefectures across Japan from April 2017 to December 2019, we extracted AMI data for seven prefectures where these aerosol analysers were installed. The primary outcome was the relationship of PM
