Little is known about the impacts of specific chemical components on cardiovascular hospitalizations. We examined the relationships of PM chemical composition and daily hospitalizations for cardiovascular disease in 184 Chinese cities. Acute PM chemical composition exposures were linked to higher cardiovascular disease hospitalizations on the same day and the percentage change of cardiovascular admission was the highest at 1.76% (95% CI, 1.36-2.16%) per interquartile range increase in BC, followed by 1.07% (0.72-1.43%) for SO, 1.04% (0.63-1.46%) for NH, 0.99% (0.55-1.43%) for NO, 0.83% (0.50-1.17%) for OM, and 0.80% (0.34%-1.26%) for Cl. Similar findings were observed for all cause-specific major cardiovascular diseases, except for heart rhythm disturbances. Short-term exposures to PM chemical composition were related to higher admissions and showed diverse impacts on major cardiovascular diseases.
关于特定化学物质成分对心血管疾病住院的影响知之甚少。我们研究了 PM 化学成分与 184 个中国城市心血管疾病日住院人数之间的关系。急性 PM 化学成分暴露与当天更高的心血管疾病住院人数有关，每增加一个四分位距，心血管病入院率的百分比变化最高，为 1.76%（95%置信区间：1.36-2.16%），其次是 BC（1.07%，0.72-1.43%）、SO（1.04%，0.63-1.46%）、NH（0.99%，0.55-1.43%）、NO（0.83%，0.50-1.17%）、OM（0.80%，0.34%-1.26%）和 Cl（0.80%，0.34%-1.26%）。除心律失常外，所有特定原因的主要心血管疾病都观察到了类似的发现。短期暴露于 PM 化学成分与更高的住院率有关，并且对主要心血管疾病有不同的影响。
