Abstract

Background

Cardiovascular diseases (CVDs) account for 17.9 million deaths annually. Behavioral risk factors increase the risk of dying from CVD. Air pollution is not included in this risk calculation since the appreciation of air pollution as a modifiable risk factor is still limited. The purpose of this study was to analyze CVD mortality attributed to air pollution in all World Health Organization WHO member states and demonstrate the association of CVD mortality with air pollution depending on countries' income level.

Methods

The CVD death rate was calculated by dividing the number of deaths by the total population. The proportion of the population with primary reliance on clean fuels and technologies for cooking was calculated as an indicator of household air pollution. The annual mean concentration of fine particulate matter ≤2.5 µg/m³ and ≤10.0 µg/m³ to which the population is exposed was used as an indicator of ambient air pollution.

Results

There is a gradual increase in CVD mortality attributed to air pollution from high-income countries (HICs) to low-income countries (LICs). Household air pollution is the major cause of CVD mortality in LICs. Ischemic heart disease mortality attributed to ambient air pollution in all countries is higher than stroke mortality attributed to ambient air pollution. In LIC, mortality from stroke is attributed to household air pollution of 39.27 ± 14.47, which is more than twice the stroke mortality attributed to ambient air pollution at 18.60 ± 5.64, t = 7.17, p < 0.01.

Conclusion

Air pollution control should be an essential component of the CVD preventive strategy, along with lifestyle modifications and effective disease management.

不同社会经济地位国家的心血管疾病死亡率与空气污染

心血管疾病（CVD）每年造成 1790 万人死亡。行为风险因素会增加死于心血管疾病的风险。由于对空气污染作为可改变风险因素的认识仍然有限，因此空气污染未被纳入风险计算。本研究的目的是分析世界卫生组织所有成员国因空气污染导致的心血管疾病死亡率，并根据各国的收入水平证明心血管疾病死亡率与空气污染的关系。计算主要依靠清洁燃料和技术做饭的人口比例，作为家庭空气污染的指标。人口所接触的细颗粒物年均浓度≤2.5 µg/m3 和≤10.0 µg/m3 被用作环境空气污染指标。家庭空气污染是导致低收入国家心血管疾病死亡的主要原因。在所有国家，环境空气污染导致的缺血性心脏病死亡率高于环境空气污染导致的中风死亡率。在低收入国家，家庭空气污染导致的中风死亡率为 39.27 ± 14.47，是环境空气污染导致的中风死亡率（18.60 ± 5.64）的两倍多，t = 7.17，p < 0.01。
