Evidence on the impacts of PM1, PM2.5, and PM10 on the hospital admissions, length of hospital stays (LOS), and hospital expenses among patients with cardiovascular disease (CVD) is still limited in China, especially in rural areas. This study was performed in eight counties of Fuyang from 1 January 2015 to 30 June 2017. We use a three-stage time-series analysis to explore the effects of short-term exposure to PM1, PM2.5, and PM10 on hospital admissions, LOS, and hospital expenses for CVDs. An increment of 10 ug/m3 in PM1, PM2.5, and PM10 corresponded to an increment of 1.82% (95% CI: 1.34, 2.30), 0.96% (95% CI: 0.44, 1.48), and 0.79% (95% CI: 0.63%, 0.95%) in CVD hospital admissions, respectively. We observed that daily concentrations of PMs were associated with an increase in hospital admissions, LOS, and expenses for CVDs. Sustained endeavors are required to reduce air pollution so as to attenuate disease burdens from CVDs.
在中国，关于细颗粒物（PM1）、可入肺颗粒物（PM2.5）和可吸入颗粒物（PM10）对心血管疾病（CVD）患者的住院率、住院时长（LOS）和住院费用影响的证据仍然有限，尤其是在农村地区。本研究于2015年1月1日至2017年6月30日在阜阳的八个县开展。我们采用三阶段时间序列分析，以探究短期暴露于PM1、PM2.5和PM10对心血管疾病的住院率、住院时长和住院费用的影响。PM1、PM2.5和PM10每增加10微克/立方米，心血管疾病住院率分别相应增加1.82%（95%置信区间：1.34，2.30）、0.96%（95%置信区间：0.44，1.48）和0.79%（95%置信区间：0.63%，0.95%）。我们观察到，颗粒物的日浓度与心血管疾病的住院率、住院时长和费用增加有关。需要持续努力减少空气污染，以减轻心血管疾病带来的疾病负担。
