Whether or not inhalation of airborne desert dust has adverse health effects is unknown. The present study, based on a systematic review and meta-analysis, was carried out to assess the influence desert dust on cardiovascular mortality, acute coronary syndrome, and heart failure.
A systematic search was made in PubMed and Embase databases for studies published before March 2020. Studies based on daily measurements of desert dust were identified. The meta-analysis evaluated the impact of desert dust on cardiovascular events the same day (lag 0) of the exposure and during several days after the exposure (lags 1 to 5). The combined impact of several days of exposure was also evaluated. The incidence rate ratio (IRR) with 95% confidence intervals (CI) was calculated using the inverse variance random effects method.
Of the 589 identified titles, a total of 15 studies were selected. The impact of desert dust on the incidence of cardiovascular mortality was statistically significant (IRR = 1.018 (95%CI 1.008-1.027); < 0.001) in lag 0 of the dust episode, in the following day (lag 1) (IRR = 1.005 (95%CI 1.001-1.009); = 0.022), and during both days combined (lag 0-1) (IRR = 1.015 (95%CI 1.003-1.028); = 0.014).
The inhalation to desert dust results in a 2% increase (for every 10 µg/m) in cardiovascular mortality risk.
吸入空气中的沙漠尘土是否会对健康产生不良影响尚不清楚。本研究基于系统评价和荟萃分析，旨在评估沙漠尘土对心血管疾病死亡率、急性冠状动脉综合征和心力衰竭的影响。
在PubMed和Embase数据库中进行系统检索，查找2020年3月之前发表的研究。确定基于每日沙漠尘土测量的研究。荟萃分析评估了沙漠尘土在暴露当天（滞后0天）以及暴露后几天（滞后1至5天）对心血管事件的影响。还评估了连续几天暴露的综合影响。采用逆方差随机效应方法计算95%置信区间（CI）的发病率比（IRR）。
在589篇已识别的标题中，共选择了15项研究。沙漠尘土对心血管疾病死亡率发病率的影响在沙尘事件的滞后0天（IRR = 1.018（95%CI 1.008 - 1.027）；P < 0.001）、次日（滞后1天）（IRR = 1.005（95%CI 1.001 - 1.009）；P = 0.022）以及两天综合（滞后0 - 1天）（IRR = 1.015（95%CI 1.003 - 1.028）；P = 0.014）时具有统计学意义。
吸入沙漠尘土会使心血管疾病死亡风险增加2%（每10微克/立方米）。
