本研究的目的是使用加速度计测量慢性心力衰竭（CHF）患者的日常步行表现，以研究该参数是否是纽约心脏协会分级的决定因素，并指示最大和功能运动能力。方法50例慢性心力衰竭患者在进行日常工作时连续7天佩戴加速度计。最大运动能力和功能运动能力分别通过心肺（VO(2peak)）和6分钟步行测试进行评估。结果纽约心脏协会I、II和III组患者的平均总步行时间（TWT）分别为160.6 +/- 35.8分钟、133.9 +/- 59.0分钟和76.1 +/- 22.5分钟/天，其中19%、19%和9%为快速步行模式（> 83 m/分钟）。TWT与VO（2peak）呈显著相关(r = 0.72
Purpose The purpose of this study was to use an accelerometer to measure daily walking performance in patients with chronic heart failure (CHF) to investigate if this parameter is a determinant of New York Heart Association class and indicative of maximal and functional exercise capacity.Methods Fifty patients with CHF were instructed to wear an accelerometer for 7 consecutive days while going about their daily business. Maximal and functional exercise capacity was assessed by cardiopulmonary (VO(2peak)) and 6-minute walk testing, respectively.Results Patients in New York Heart Association I, II, and III reached an average total walking time (TWT) of 160.6 +/- 35.8 minutes, 133.9 +/- 59.0 minutes, and 76.1 +/- 22.5 minutes per day of which 19%, 19%, and 9% where spent in the fast walking mode (> 83 m/minute), respectively. The TWT correlated strongly with VO(2peak) (r = 0.72; P
