Six-minute walk distance (6MWD) of 300 and 400 m are important targets of functional capacity. The present study was performed to determine cutoff values of physical function associated with 6MWD   65 years (median age, 75: interquartile range, 71–80, 607 men) with HF. 6MWD &lt; 300 and &lt; 400 m were seen in 323 patients (32.3%) and 658 patients (65.7%), respectively. Handgrip strength, QIS, OLST, and 5STS were associated with 6MWD &lt; 300 and &lt; 400 m, respectively ( P  &lt; 0.001). The cutoff values of handgrip strength, QIS, OLST, and 5STS were 18.9 kg, 35.0% body mass (BM), 9.1 s, and 9.5 s for 6MWD &lt; 300 m, and 21.9 kg, 40.0% BM, 12.0 s, and 8.8 s for &lt; 400 m, respectively. The cutoff values of physical function could be used to set cardiac rehabilitation goals and limiting determinants of reduced functional capacity in a clinical setting in elderly patients with HF.
