摘要：

Aims The 6-min walk test (6MWT) is a widely accepted tool for evaluating exercise tolerance and physical capacity, and the 6-min walk distance (6MWD) is an established prognostic factor in patients with heart failure (HF). However, the prognostic implications of post-6MWT dyspnoea remain unknown. We aimed to investigate the prognostic value of Borg scores after the 6MWT in patients with HF.Methods and results Patients hospitalized for HF who underwent the 6MWT before discharge were included. Post-test dyspnoea was assessed using the Borg scale. Patients were stratified into low and high Borg score groups based on the median Borg score. The primary outcome was 2-year mortality. Among 1185 patients analysed, the median Borg score was 12. The 6MWD was significantly shorter in the high Borg score group than in the low Borg score group. The 2-year mortality rate was 20.2%. In the Kaplan-Meier analysis, the high Borg score group demonstrated an association with 2-year mortality, which remained significant even after adjustment for conventional risk factors, including the 6MWD. Furthermore, the Borg scale provided significant net reclassification improvement to the conventional risk model incorporating 6MWD.Conclusion In hospitalized patients with HF, post-6MWT Borg scores were associated with 2-year mortality independent of the 6MWD, providing incremental prognostic value to the 6MWD. Even if patients are able to walk long distances for 6 min, it is essential to closely observe dyspnoea immediately thereafter. Our study investigated the significance of breathlessness after a walking test in patients with heart failure and found that this provides important information about their prognosis. The key findings are as follows:Patients with heart failure who felt more breathless after the 6-min walk test (6MWT) were at a higher risk of mortality within 2 years.The level of breathlessness after the 6MWT provided additional information about prognosis beyond just how far patients could walk during the test.
