    Article - En anglais

    Fulltext.

    Objectives

    Preexisting data sets were used to investigate the association between hospital admissions for congestive heart failure and air pollutants.

    Methods

    Medicare hospital admissions data, ambient air pollution monitoring data, and meteorological data were used to create daily values of hospital admissions for congestive heart failure, maximum hourly temperature, and maximum hourly levels of carbon monoxide, nitrogen dioxide, sulfur dioxide, and ozone.

    Data were compiled for each of seven cities (Chicago, Detroit, Houston, Los Angeles, Milwaukee, New York, and Philadelphia) for 1986 through 1989.

    Single-pollutant and multipollutant models with adjustments for temperature, seasonal effects, and weekly cycles were used in conducting negative binomial regression analyses.

    Results

    Ambient carbon monoxide levels were positively associated with hospital admissions for congestive heart failure in the single-pollutant and multipollutant models for each of the seven cities.

    The relative risk of hospital admission for congestive heart failure associated with an increase of 10 ppm in carbon monoxide ranged from 1.10 in New York to 1.37 in Los Angeles.

    Conclusions

    Hospital admissions for congestive heart failure exhibited a consistent association with daily variations in ambient carbon monoxide.

    This association was independent of season, temperature, and other major gaseous pollutants.
