CONTEXT: Short-term exposure to high levels of air pollution may trigger myocardial infarction (MI), but this association remains unclear.


OBJECTIVE: To assess and quantify the association between short-term exposure to major air pollutants (ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter ≤10 μm [PM(10)] and ≤2.5 μm [PM(2.5)] in diameter) on MI risk.


DATA SOURCES: EMBASE, Ovid MEDLINE in-process and other nonindexed citations, and Ovid MEDLINE (between 1948 and November 28, 2011), and EBM Reviews-Cochrane Central Register of Controlled Trials and EBM Reviews-Cochrane Database of Systematic Reviews (between 2005 and November 28, 2011) were searched for a combination of keywords related to the type of exposure (air pollution, ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, PM(10), and PM(2.5)) and to the type of outcome (MI, heart attack, acute coronary syndrome).


STUDY SELECTION: Two independent reviewers selected studies of any study design and in any language, using original data and investigating the association between short-term exposure (for up to 7 days) to 1 or more air pollutants and subsequent MI risk. Selection was performed from abstracts and titles and pursued by reviewing the full text of potentially eligible studies.


DATA EXTRACTION: Descriptive and quantitative information was extracted from each selected study. Using a random effects model, relative risks (RRs) and 95% CIs were calculated for each increment of 10 μg/m(3) in pollutant concentration, with the exception of carbon monoxide, for which an increase of 1 mg/m(3) was considered.


DATA SYNTHESIS: After a detailed screening of 117 studies, 34 studies were identified. All the main air pollutants, with the exception of ozone, were significantly associated with an increase in MI risk (carbon monoxide: 1.048; 95% CI, 1.026-1.070; nitrogen dioxide: 1.011; 95% CI, 1.006-1.016; sulfur dioxide: 1.010; 95% CI, 1.003-1.017; PM(10): 1.006; 95% CI, 1.002-1.009; and PM(2.5): 1.025; 95% CI, 1.015-1.036). For ozone, the RR was 1.003 (95% CI, 0.997-1.010; P = .36). Subgroup analyses provided results comparable with those of the overall analyses. Population attributable fractions ranged between 0.6% and 4.5%, depending on the air pollutant.


CONCLUSION: All the main air pollutants, with the exception of ozone, were significantly associated with a near-term increase in MI risk.


データ・ソース:EMBASE、オービットMEDLINE製造過程の、そして、他は引用とオービットMEDLINE(1948と2011年11月28日の間に)に非インデックスを付けた、そして、Controlled TrialsのEBM Reviews-コクラン本部RegisterとSystematic Reviews(2005と2011年11月28日の間に)のEBM Reviews-コクランDatabaseは暴露(大気汚染、オゾン、一酸化炭素、二酸化窒素、二酸化硫黄、PM(10)とPM(2.5))の型に関連したキーワードの組合せのために、そして、結果(MI、心発作、急性冠症候群)の型に検索された。
オゾンのために、RRは1.003であった(95%CI、0.997-1.010;P = .36)。
