However, the prognostic significance of 6MWT interruption remains unclear. Therefore, this study investigated the prognostic implications of 6MWT interruption in patients with heart failure (HF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients hospitalized with HF who underwent 6MWT before discharge were included.

During the 2\u2010year follow\u2010up period, 238 patients (20.2%) died. In the Kaplan\u2013Meier analysis, 6MWT interruption due to dyspnea\/leg fatigue was associated with a significantly higher 2\u2010year mortality rate, which remained significant even after adjustment for conventional risk factors, including the 6MWD and the Borg score measured after the 6MWT. However, 6MWT interruption for other reasons was not significantly associated with mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      In hospitalized patients with HF, 6MWT interruption due to dyspnea or leg fatigue was independently associated with higher 2\u2010year mortality, regardless of the 6MWD.
