The aim of this study was to evaluate the effects of a mobile health (mHealth) intervention, HerBeat, compared with educational usual care (E-UC) for improving exercise capacity (EC) and other patient-reported outcomes at 3 mo among women with coronary heart disease.
Women were randomized to the HerBeat group (n = 23), a behavior change mHealth intervention with a smartphone, smartwatch, and health coach or to the E-UC group (n = 24) who received a standardized cardiac rehabilitation workbook. The primary endpoint was EC measured with the 6-min walk test (6MWT). Secondary outcomes included cardiovascular disease risk factors and psychosocial well-being.
A total of 47 women (age 61.2 ± 9.1 yr) underwent randomization. The HerBeat group significantly improved on the 6MWT from baseline to 3 mo ( P = .016, d = .558) while the E-UC group did not ( P = .894, d =-0.030). The between-group difference of 38 m at 3 mo was not statistically significant. From baseline to 3 mo, the HerBeat group improved in anxiety ( P = .021), eating habits confidence ( P = .028), self-efficacy for managing chronic disease ( P = .001), diastolic blood pressure ( P = .03), general health perceptions ( P = .047), perceived bodily pain ( P = .02), and waist circumference ( P = .008) while the E-UC group showed no improvement on any outcomes.
The mHealth intervention led to improvements in EC and several secondary outcomes from baseline to 3 mo while the E-UC intervention did not. A larger study is required to detect small differences between groups. The implementation and outcomes evaluation of the HerBeat intervention was feasible and acceptable with minimal attrition.
本研究旨在评估移动健康（mHealth）干预措施 HerBeat 与教育常规护理（E-UC）相比，在 3 个月时对改善冠心病女性的运动能力（EC）和其他患者报告结果的效果。
将女性随机分为 HerBeat 组（n=23），即使用智能手机、智能手表和健康教练的行为改变 mHealth 干预组，或 E-UC 组（n=24），他们接受标准化的心脏康复手册。主要终点是使用 6 分钟步行试验（6MWT）测量的 EC。次要结果包括心血管疾病风险因素和心理社会健康。
共有 47 名女性（年龄 61.2±9.1 岁）接受了随机分组。HerBeat 组从基线到 3 个月时在 6MWT 上显著改善（P=0.016，d=0.558），而 E-UC 组没有（P=0.894，d=-0.030）。3 个月时组间差异为 38m，但无统计学意义。从基线到 3 个月，HerBeat 组在焦虑方面有所改善（P=0.021）、饮食习惯信心（P=0.028）、管理慢性病的自我效能（P=0.001）、舒张压（P=0.03）、一般健康感知（P=0.047）、身体疼痛感知（P=0.02）和腰围（P=0.008），而 E-UC 组在任何结果上均无改善。
与 E-UC 干预相比，mHealth 干预在 3 个月时导致 EC 和一些次要结果的改善，而 E-UC 干预则没有。需要更大的研究来检测两组之间的微小差异。HerBeat 干预的实施和结果评估是可行和可接受的，仅出现少量脱落。
