Association between PM2.5 and risk of hospitalization for myocardial infarction: a systematic review and a meta-analysis.

ABSTRACT: BACKGROUND:It is generally assumed that there have been mixed results in the literature regarding the association between ambient particulate matter (PM) and myocardial infarction (MI). The aim of this meta-analysis was to explore the rate of short-term exposure PM with aerodynamic diameters ?2.5??m (PM2.5) and examine its potential effect(s) on the risk of MI. METHODS:A systematic search was conducted on databases like PubMed, Scopus, Web of Science, and Embase with components: "air pollution" and "myocardial infarction". The summary relative risk (RR) and 95% confidence intervals (95%CI) were also calculated to assess the association between the PM2.5 and MI. RESULTS:Twenty-six published studies were ultimately identified as eligible candidates for the meta-analysis of MI until Jun 1, 2018. The results illustrated that a 10-?g/m 3 increase in PM2.5 was associated with the risk of MI (RR?=?1.02; 95% CI 1.01-1.03; P???0.0001). The heterogeneity of the studies was assessed through a random-effects model with p?
