Surveillance of the short-term impact of fine particle air pollution on cardiovascular disease hospitalizations in New York State

Abstract

BackgroundStudies have shown that the effects of particulate matter on health vary based on factors including the vulnerability of the population, health care practices, exposure factors, and the pollutant mix.MethodsWe used time-stratified case-crossover to estimate differences in the short-term impacts of PM2.5 on cardiovascular disease hospital admissions in New York State by geographic area, year, age, gender, co-morbid conditions, and area poverty rates.ResultsPM2.5 had a stronger impact on heart failure than other cardiovascular diagnoses, with 3.1% of heart failure admissions attributable to short-term PM2.5 exposure over background levels of 5 ug/m3. Older adults were significantly more susceptible to heart failure after short-term ambient PM2.5 exposure than younger adults.ConclusionThe short-term impact of PM2.5 on cardiovascular disease admissions, and modifications of that impact, are small and difficult to measure with precision. Multi-state collaborations will be necessary to attain more precision to describe spatiotemporal differences in health impacts.

Spatiotemporal Analysis of Ambient Air Pollution Exposure and Respiratory Infections Cases in Beijing

“…Zhang et al has reported the population exposure to these particles in high-exposure areas of Beijing (4) during the autumn of 2012. Air pollution has been shown to contribute to patient morbidity and mortality (5)(6)(7)(8). The risk associated with different duration of exposure and amount of exposure has not been well defined.…”

Short-Term Effects of Fine Particulate Air Pollution on Ischemic Heart Disease Hospitalizations in Taipei: A Case-Crossover Study

“…Haley et al (2009) conducted a study in New York State, and found no evidence of an association between IHD admissions and exposure to fine particles. A study in Helsinki by Halonen et al (2009) also reported no evidence of positive associations between IHD admissions and PM 2.5 .…”

“…Relatively few epidemiologic studies have been undertaken which address specifically the health effects of PM 2.5 because only few cities have monitored PM 2.5 recently (Host et al, 2008). Several studies have investigated the relationship between fine particles and hospital admissions (or ER visits) for ischemic heart disease (IHD) (Dominici et al, 2006;Host et al, 2008;Haley et al, 2009;Halonen et al, 2009;Zanobetti et al, 2009). Because these studies were conducted primarily in America and some European cities, the findings may not be applicable to Taiwan, which possibly has different air pollutant mixtures.…”

Polución por material particulado fino (PM 2,5) incrementa las hospitalizaciones por insuficiencia cardiaca

“…Probablemente, varios de estos mecanismos participan en forma simultánea en pacientes de los grupos más suceptibles. La aparente paradoja del incremento de riesgo en individuos con antecedentes de hipertensión y edad menor a 74 años puede depender de factores no evaluados en este estudio, como diferencias geográficas y socioculturales que influyen en el patrón de exposición a polutantes 35,36 . Limitación: Con respecto a la magnitud de los intervalos de riesgo observados en Santiago, si bien los resultados son robustos, pensamos que tiene que ver con la cantidad de pacientes que estamos integrando.…”
