    Recently, a research article was published in JAHA, an authoritative journal in the field of cardiovascular disease.
    This retrospective cohort study included 96,582 adults from Kaiser Permanente in Northern California who had a
    history of
    stroke or acute myocardial infarction.
    The researchers obtained the subject's outcome, covariate, and address data from the electronic health record, and correlated it with a 1-year average PM2.
    5 exposure estimate based on changes in residential location over time.

    Stroke

    The Cox proportional hazards model estimated the risks of stroke, acute myocardial infarction, and cardiovascular death associated with PM2.
    5 exposure, and adjusted for multiple covariates.
    The secondary analysis estimates that the risk is lower than the federal and state regulations (average PM2.
    5 for a year is 12 µg/m3).

    Every 10 µg/m3 increase in average 1-year PM2.
    5 exposure was associated with an increased risk of cardiovascular death (hazard ratio [HR] 1.
    20; 95% CI 1.
    11–1.
    30), but did not increase the risk of stroke or acute myocardial infarction .
    Analysis for PM2.
    5<12 µg/m3 showed that for every 10 µg/m3 increase in the average 1-year PM2.
    5, CVD mortality (HR: 2.
    31; 95% CI: 1.
    96-2.
    71), stroke (HR: 1.
    41; The risk of 95% CI is 1.

    83) and acute
    myocardial infarction (HR is 1.
    51; 95% CI is 1.
    21–1.
    89).


    It can be seen that adults with a history of CVD are susceptible to PM2.
    5 exposure, especially the impact on CVD mortality.
    The increased risk is observed at exposure levels of PM2.
