We read with interest the paper by Sofianopoulou et al. [1]. The authors have significantly contributed to highlighting the potential link between air pollution and health outcomes among pulmonary arterial hypertension (PAH) patients, by showing that exposure to particulate matter with an aerodynamic diameter smaller than 2.5 µm (PM_2.5) was significantly associated with transplant-free survival, and that traffic-related air pollution was correlated with the European Society of Cardiology (ESC)/European Respiratory Society (ERS) risk categories and haemodynamics at baseline.

暴露于住宅空气污染对肺动脉高压患者的健康影响：比利时的一项队列研究

我们感兴趣地阅读了 S 的论文奥亚诺普卢 等人。[1]。作者通过表明暴露于空气动力学直径小于 2.5 µm (PM _2.5 ) 的颗粒物与移植显着相关，为突出肺动脉高压 (PAH) 患者的空气污染与健康结果之间的潜在联系做出了重大贡献。自由生存，交通相关的空气污染与欧洲心脏病学会（ESC）/欧洲呼吸学会（ERS）的风险类别和基线血流动力学相关。
