Few studies report objective accelerometer-measured daily physical activity levels in patients with heart failure (HF).
We examined baseline accelerometer-measured physical activity from the Heart Failure Exercise and Resistance Training Camp trial, a federally funded (R01-HL112979) 18-month intervention study to promote adherence to exercise in patients with HF. Factors associated with physical activity levels were also explored.
Patients with diagnosed HF (stage C chronic HF confirmed by echocardiography and clinical evaluation) were recruited from 2 urban medical centers. Physical activity energy expenditure and the number of minutes of moderate or vigorous physical activity (MVPA) were obtained from 7 full days of measurement with the accelerometer (Actigraph Model GT3X, Pensacola, Florida) for 182 subjects who met minimum valid wear time parameters. Additional measures of health-related factors were included to explore the association with physical activity levels.
Subjects had 10.2 ± 10.5 minutes of MVPA per day. Total physical activity energy expenditure was 304 ± 173 kcal on average per day. There were 23 individuals (12.6%) who met the recommended goal of 150 minutes of MVPA per week. Men, whites, New York Heart Association class II, and subjects with better physical function had significantly higher levels of activity.
Consistent with previous research, patients with HF are not meeting recommended guidelines for 150 minutes of MVPA per week.
很少有研究报告心力衰竭（HF）患者的客观加速度计测量的日常体力活动水平。
我们检查了心力衰竭运动和阻力训练营试验的基线加速度计测量的体力活动，这是一项由联邦政府资助的（R01-HL112979）为期 18 个月的干预研究，旨在促进 HF 患者对运动的依从性。还探讨了与体力活动水平相关的因素。
从 2 个城市医疗中心招募了诊断为 HF（通过超声心动图和临床评估确认的 C 期慢性 HF）的患者。182 名符合最低有效佩戴时间参数的受试者使用加速度计（Actigraph Model GT3X，佛罗里达州彭萨科拉）进行了 7 天的完整测量，获得了体力活动能量消耗和中等或剧烈体力活动（MVPA）的分钟数。还包括了其他健康相关因素的测量，以探讨与体力活动水平的关联。
受试者每天有 10.2 ± 10.5 分钟的 MVPA。平均每天的总体力活动能量消耗为 304 ± 173 卡路里。有 23 名患者（12.6%）达到了每周 150 分钟 MVPA 的推荐目标。男性、白人、纽约心脏协会（NYHA）心功能 II 级和身体功能较好的患者活动水平明显更高。
与之前的研究一致，HF 患者没有达到每周 150 分钟 MVPA 的推荐指南。
