DESCRIPTION: (Adapted from the Applicant's Abstract): The study of morbidity and mortality associated with air pollution historically has focused on respiratory disease. Preliminary studies by the investigators using air monitoring data together with Medicare administrative data demonstrate an association of daily levels of both carbon monoxide (CO) and airborne particulates less than 10 microns in diameter (PM10) with daily hospital admissions among Medicare recipients for cardiovascular disease. The proposed study will extend these analyses to explore the association between air pollution and cardiovascular disease and the investigate factors that may affect that association. Four specific hypotheses will be addressed. First, we propose to look at the independent and interactive effects of these pollutants on a broader range of cardiovascular conditions in eight different cities than considered in preliminary studies to determine the consistency of these relationships. Second, we will examine the modulating effect of temperature and humidity on the cardiovascular effects of these pollutants. Third, we will examine the influence of particle characteristics on the link between particulates and cardiovascular disease using detailed sampling data from Philadelphia. Finally, we will study a sub-population of Medicare beneficiaries comprised of persons with a history of hospital admissions for chronic respiratory disease to evaluate degree to which the association between cardiovascular disease and air pollution is driven by respiratory effects. Given the tremendous impact of cardiovascular disease on public health, the possibility that air pollution plays a significant role in the exacerbation of these conditions has major ramifications. The proposed research seeks to extend our knowledge concerning the health effects of air pollution in this important new direction.

描述：（改编自申请人的摘要）： 与空气污染相关的发病率和死亡率历来 专注于呼吸系统疾病。 调查人员的初步研究 使用空气监测数据和医疗保险管理数据 证明了一氧化碳（CO）和 空气中直径小于10微米的颗粒物（PM10）， 因心血管疾病住院的医疗保险接受者。 拟议的研究将扩展这些分析，以探讨 大气污染与心血管疾病的关系及其影响因素 这可能会影响这种联系。 四个具体的假设将是 处理。 首先，我们建议研究独立和互动 这些污染物对更广泛的心血管疾病的影响 在八个不同的城市比在初步研究中考虑， 确定这些关系的一致性。 第二，我们将研究 温湿度对心血管系统的调节作用 这些污染物的影响。 第三，我们将研究 微粒与心血管疾病之间联系的微粒特性 使用费城的详细抽样数据。 最后我们将 研究了一个医疗保险受益人的亚人群， 慢性呼吸道疾病住院史，以评估 心血管疾病和空气之间的关联程度 污染是由呼吸作用造成的。 考虑到 心血管疾病对公众健康的影响，空气污染 在这些疾病的恶化中发挥着重要作用 后果 这项拟议中的研究旨在扩展我们的知识 关于空气污染对健康的影响， 方向
