In the evaluation method established in this study, the way to control the influence of drug use can provide methodological reference for future research in related fields, and the comprehensive analysis of the protective effects of air purifiers on cardiovascular system from multiple indicators of inflammation, coagulation, plaque stability and blood lipid can also provide scientific basis for screening sensitive indicators of air purification protection for patients with SCAD. In addition, through a randomized crossover intervention study with small sample size, the study found that the use of air purifier had a clear protective effect on patients with SCAD, in the case of daily routine medication management for disease management, and could significantly improve patients' inflammation indicator CRP and blood lipid indicator HDL-C. It shows that using air purifiers is one of the effective measures to protect the health of patients with SCAD in PM
