Abstract:Objective To explore the effect of fine particulate matter exposure on reducing the detection rate of EF slope of mitral valve. Methods Workers with health examination in Kailuan Group were selected during the same period. Workers with first-stage pneumoconiosis served as the exposure group, while workers without dust exposure history were considered as the control group. SPSS 17.0 software was used to statistically analyze the cardiac ultrasound Results of the two groups. Results Mitral valve EF slope rate was significantly lower in the exposure group than in the control group ((73.20±20.53) mm/s vs. (78.74±24.11)mm/s, t=14.521, P<0.001). The detection rate of mitral valve EF slope reduction was higher in the exposure group than in the control group (52.4% vs. 40.5%, χ2=22.874, P<0.001). Exposure to fine particulate matters was second only to age and systolic pressure in terms of the risk factors affecting the decrease of mitral valve EF slope, and the OR value was 1.744 (95%CI:1.395-2.180) after the factors such as body mass index (BMI ) were excluded. Conclusion Fine particulate matter exposure is an independent risk factor for the decrease of mitral valve EF slope.
