研究目的-估计空气污染水平和心血管疾病的急诊入院率之间的短期关联在瓦伦西亚，在1994-1996 period. Design-每日水平的空气污染和心血管疾病的急诊入院率与使用生态时间序列设计。入院人数来自医院记录数据库。选定的原因组都是心血管疾病，心脏病入院，脑血管疾病入院。以消化系统疾病住院人数为对照。污染物为黑烟、二氧化硫（SO2）、二氧化氮（NO2）、一氧化碳（CO）和臭氧（O-3）。关联程度通过Poisson自回归估计。估计是根据最热的（5月至10月）和最冷（11月至4月）期间。设置城市的瓦伦西亚，西班牙，约750 000居民。内裤-人们被接纳到两个主要医院在城市，与一个集水区的近400 000居民。主要结果-对于整个期间，发现SO2-24 h与心血管疾病的预期入院人数显著相关，因此其水平升高10 mug/m3与增加3%（95%CI 0.4 - 5.7%）相关。一个显着的关联黑烟，SO2-24小时，SO2-1小时，CO-1小时被发现在最热的学期。所有这些关联都在两天后得到验证。颗粒物、二氧化硫和一氧化碳的关联估计受到模型中其他污染物的影响。NO2与脑血管入院独立相关。有没有显着的空气污染和入院消化diseases. Conclusions，目前的空气污染水平和紧急心血管入院率显着相关的瓦伦西亚。
Study objective-To estimate the shortterm association between air pollution levels and emergency hospital admissions for cardiovascular diseases in Valencia, within 1994-1996 period.Design-Daily levels of air pollution and emergency admissions for cardiovascular diseases were related to using an ecological time series design. The number of admissions was obtained from the hospital records database. Selected groups of causes were all cardiovascular diseases, heart admissions, and admissions for cerebrovascular diseases. The number of admissions for digestive diseases was used as control. Pollutants were black smoke, sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O-3). Magnitude of association was estimated by Poisson autoregresive regression. Estimations were calculated according the hottest (May to October) and the coldest (November to April) periods.Setting-City of Valencia, Spain, about 750 000 inhabitants.Participants-People being admitted to the two major hospitals in the city, with a catchment area of nearly 400 000 inhabitants.Main results-For the whole period, a significant association for SO2-24 h was found so a rise in its levels of 10 mug/m(3) was associated with an increment of 3% (95%CI 0.4 to 5.7%) in the expected number of cardiovascular admissions. A significant association for black smoke, SO2-24 h, SO2-1 h, and CO-1 h was found in the hottest semester. All these associations were verified with a lag of two days. The estimates of the associations for particles, SO2, and CO were affected by the inclusion of the other pollutants in their models. NO2 was independently associated with cerebrovascular admissions. There were no significant associations between air pollution and admissions for digestive diseases.Conclusions-Current levels of air pollution and emergency cardiovascular admissions are significantly related in Valencia.
