摘要: Background: Dust storm is a meteorological phenomenon and dust particles have been suspected as harmful to heart lungs. The aim of this study was investigate the association between coarse emergency hospital admissions for cardiovascular diseases (CVD) in Hong Kong. Methods Results: Data on mean daily CVD major hospitals Kong, concentrations air pollutants variables from January 1998 December 2002 were obtained several government departments. We identified 5 days during period. Independent t-tests used compare number non-dust days. Case-crossover analysis, using Poisson regression, examine effects particles' concentration CVD. A marginally significant increase ischemic disease (IHD) found with RR=1.04 (95% confidence interval: 1.00, 1.08) per 10μg/m3 particles. Conclusions: This demonstrated IHD day events when levels very high. Further studies are required assess role cardiac health. (Circ J 2012; 76: 655-660)
