The Six-Minute Walk Test (6MWT) traditionally assesses exercise capacity in cardiac patients but requires a large space. The Six-Minute Stepper Test (6MST) has been validated as an alternative in various populations. This study evaluates the reproducibility, sensitivity, and validity of the 6MST in 60 cardiac patients (15 women, 45 men, 58 ± 11.2 years). Participants underwent cardiopulmonary exercise tests (CPET), two 6MSTs, and one 6MWT at the start and end of cardiac rehabilitation (CR). Performance in the 6MST improved significantly after CR (343 ± 89.0 vs. 451 ± 105.6 steps, p < 0.0001). The 6MST showed moderate correlation with the 6MWT and CPET (r = 0.54, p < 0.0001). Dyspnoea and leg fatigue were higher in the 6MST than in the 6MWT (p < 0.0001). Conclusion: The 6MST is a safe, valid, sensitive, and reproducible tool for evaluating exercise capacity in cardiac patients, comparable to the 6MWT.
六分钟步行试验（6MWT）传统上用于评估心脏病患者的运动能力，但需要较大空间。六分钟踏阶试验（6MST）已被验证可作为适用于各类人群的替代方法。本研究评估了6MST在60例心脏病患者（15名女性，45名男性，年龄58±11.2岁）中的可重复性、敏感性和有效性。参与者在心脏康复（CR）开始和结束时接受了心肺运动试验（CPET）、两次6MST和一次6MWT。CR后6MST的表现显著改善（343±89.0步对451±105.6步，p<0.0001）。6MST与6MWT和CPET呈中度相关（r=0.54，p<0.0001）。6MST中的呼吸困难和腿部疲劳高于6MWT（p<0.0001）。结论：6MST是一种用于评估心脏病患者运动能力的安全、有效、敏感且可重复的工具，与6MWT相当。
