Abstract:
Objective To understand the acute effect of the air pollution on daily mortality of cardiovascular diseases in the old people aged over 65 years in Taiyuan, Shanxi, China. Methods Case-crossover design was used to assess the association between air pollution and daily cardiovascular disease mortality. Pollutants considered were nitrogen dioxide (NO2), carbon monoxide (CO), inhalable particles (PM10) and sulfur dioxide (SO2). Results CO exposure was significantly associated with the mortality of five kinds of cardiovascular diseases. No association was found for arrhythmia. As CO concentration increased by 100 ?g/m3, the corresponding OR of cardiovascular disease mortality were as follows, total cardiovascular disease mortality were1.000-1.013, cardiac mortality were1.000-1.024, ischemic heart disease were 1.005-1.032, cardiac failure were 1.006-1.112, myocardial infarction were 1.009-1.050 respectively. The higher OR value was found in unidirectional control design than that in the bidirectional design. Considering the lag effect of air pollution, the 24 hr and 48 hr average of air pollution levels were analyzed in the present study respectively. Conclusion The current air pollution level (PM10, CO) in Taiyuan City has a acute effect on the cardiovascular disease mortality in the local old people aged over 65 years.
