Guidelines recommend exercise training as a component of heart failure management. There are large disparities in access to rehabilitation, and introducing hybrid comprehensive telerehabilitation (HCTR) consisting of remote monitoring of training at patients' homes might be an appealing alternative.
To assess whether potential improvements in quality-of-life outcomes after a 9-week HCTR intervention in patients with heart failure translate into improvement in clinical outcomes during extended 12 to 24 months of follow-up, compared with usual care.
DESIGN, SETTING, AND PARTICIPANTS: The Telerehabilitation in Heart Failure Patients (TELEREH-HF) trial is a multicenter, prospective, open-label, parallel-group randomized clinical trial that enrolled 850 patients with heart failure up to 6 months after a cardiovascular hospitalization with New York Heart Association levels I, II, or III and left ventricular ejection fraction of 40% or less. Patients from 5 centers in Poland were randomized 1:1 to HCTR plus usual care or usual care only and followed up for 14 to 26 months after randomization.
During the first 9 weeks, patients underwent either an HCTR program (1 week in hospital and 8 weeks at home) or usual care with observation. The HCTR intervention encompassed telecare, telerehabilitation, and remote monitoring of implantable devices. No intervention occurred in the remaining study period.
The percentage of days alive and out of the hospital from randomization through the end of follow-up at 14 to 26 months.
A total of 850 patients were enrolled, with 425 randomized to the HCTR group (377 male patients [88.7%]; mean [SD] age, 62.6 [10.8] years) and 425 randomized to usual care (376 male patients [88.5%]; mean [SD] age, 62.2 [10.2] years). The HCTR intervention did not extend the percentage of days alive and out of the hospital. The mean (SD) days were 91.9 (19.3) days in the HCTR group vs 92.8 (18.3) days in the usual-care group, with the probability that HCTR extends days alive and out of the hospital equal to 0.49 (95% CI, 0.46-0.53; P = .74) vs usual care. During follow-up, 54 patients died in the HCTR arm and 52 in the usual-care arm, with mortality rates at 26 months of 12.5% vs 12.4%, respectively (hazard ratio, 1.03 [95% CI, 0.70-1.51]). There were also no differences in hospitalization rates (hazard ratio, 0.94 [95% CI, 0.79-1.13]). The HCTR intervention was effective at 9 weeks, significantly improving peak oxygen consumption (0.95 [95% CI, 0.65-1.26] mL/kg/min vs 0.00 [95% CI, -0.31 to 0.30] mL/kg/min; P < .001) and quality of life (Medical Outcome Survey Short Form-36 questionnaire score, 1.58 [95% CI, 0.74-2.42] vs 0.00 [95% CI, -0.84 to 0.84]; P = .008), and it was well tolerated, with no serious adverse events during exercise.
In this trial, the positive effects of a 9-week program of HCTR in patients with heart failure did not lead to the increase in percentage of days alive and out of the hospital and did not reduce mortality and hospitalization over a follow-up period of 14 to 26 months.

指南建议将运动训练作为心力衰竭管理的组成部分。在康复方面存在着巨大的差异,引入由远程监测患者家庭训练组成的混合综合远程康复(HCTR)可能是一种有吸引力的替代方法。
评估心力衰竭患者接受 9 周 HCTR 干预后的生活质量改善是否会在 12 至 24 个月的随访期间转化为临床结局的改善,与常规护理相比。
设计、地点和参与者:远程心力衰竭患者康复试验(TELEREH-HF)是一项多中心、前瞻性、开放标签、平行组随机临床试验,纳入了 850 例心力衰竭患者,这些患者在心血管住院后 6 个月内,纽约心脏协会(NYHA)分级 I、II 或 III 级,左心室射血分数为 40%或更低。来自波兰的 5 个中心的患者以 1:1 的比例随机分为 HCTR 加常规护理组或仅常规护理组,并在随机分组后随访 14 至 26 个月。
在最初的 9 周内,患者接受了 HCTR 方案(1 周住院和 8 周在家)或仅观察的常规护理。HCTR 干预包括远程护理、远程康复和植入设备的远程监测。在剩余的研究期间没有进行干预。
从随机分组到 14 至 26 个月的随访结束时,存活和出院天数的百分比。
共纳入 850 例患者,其中 425 例随机分为 HCTR 组(377 例男性患者[88.7%];平均[标准差]年龄为 62.6[10.8]岁),425 例随机分为常规护理组(376 例男性患者[88.5%];平均[标准差]年龄为 62.2[10.2]岁)。HCTR 干预并未延长存活和出院天数的百分比。HCTR 组的平均(标准差)天数为 91.9(19.3)天,常规护理组为 92.8(18.3)天,HCTR 延长存活和出院天数的概率等于 0.49(95%CI,0.46-0.53;P = .74),与常规护理相比。随访期间,HCTR 组有 54 例患者死亡,常规护理组有 52 例患者死亡,26 个月时的死亡率分别为 12.5%和 12.4%(危险比,1.03[95%CI,0.70-1.51])。住院率也没有差异(危险比,0.94[95%CI,0.79-1.13])。HCTR 干预在 9 周时有效,显著改善峰值摄氧量(0.95[95%CI,0.65-1.26]mL/kg/min 比 0.00[95%CI,-0.31 至 0.30]mL/kg/min;P < .001)和生活质量(医疗结果调查短格式 36 问卷评分,1.58[95%CI,0.74-2.42]比 0.00[95%CI,-0.84 至 0.84];P = .008),且耐受性良好,运动过程中无严重不良事件。
在这项试验中,心力衰竭患者 9 周的 HCTR 方案的积极影响并未导致存活和出院天数百分比的增加,也没有降低 14 至 26 个月随访期间的死亡率和住院率。
