Preexisting data sets were used to investigate the association between hospital admissions for congestive heart failure and air pollutants.
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.
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.
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.
利用现有的数据集研究充血性心力衰竭住院与空气污染物之间的关联。
使用医疗保险住院数据、环境空气污染监测数据和气象数据来创建充血性心力衰竭住院、最高小时温度以及一氧化碳、二氧化氮、二氧化硫和臭氧的最高小时浓度的每日数值。收集了1986年至1989年七个城市（芝加哥、底特律、休斯顿、洛杉矶、密尔沃基、纽约和费城）中每个城市的数据。在进行负二项回归分析时，使用了针对温度、季节效应和每周周期进行调整的单污染物和多污染物模型。
在七个城市各自的单污染物和多污染物模型中，环境一氧化碳浓度与充血性心力衰竭住院呈正相关。一氧化碳浓度每增加10 ppm，充血性心力衰竭住院的相对风险在纽约为1.10，在洛杉矶为1.37。
充血性心力衰竭住院与环境一氧化碳的每日变化呈现出一致的关联。这种关联独立于季节、温度和其他主要气态污染物。
