通常以6min步行距离(6-min walk distance,6MWD)作为观察指标来评估肺动脉高压(pulmonaryarterialhypertension,PAH)的治疗效果。然而,6MWD的变化与临床预后之间的关系尚未知晓。该研究旨在探讨6MWD和PAH患者临床预后之间的关系。方法 :对评估PAH患者6MWD,并报告临床转
6-minute walk distance (6MWD) is usually used as an index to evaluate the therapeutic effect of pulmonary arterial hypertension (PAH). However, the relationship between changes in 6MWD and clinical outcomes is unknown. The aim of this study was to investigate the relationship between clinical outcomes in 6MWD and PAH patients. Methods: To assess 6MWD PAH patients, and report the clinical turn
