Effectiveness of hybrid comprehensive telerehabilitation in women with heart failure - subanalysis of the TELEREH-HF RCT

Abstract

Abstract Background Despite the known benefits of cardiac rehabilitation, it remains underutilized among women. In particular, little is known about the effectiveness of hybrid comprehensive telerehabilitation (HCTR) in women with heart failure (HF). Purpose: The purpose of this study was to assess effectiveness and safety of HCTR in women with HF. Methods: The present analysis formed part of TELEREH-HF multicenter, randomized trial that enrolled 850 HF patients (NYHA I-III, LVEF ≤ 40%). Patients were randomized 1:1 to HCTR plus usual care (UC) or UC alone. Patients underwent either an HCTR (1 week in hospital and 8 weeks at home, five times weekly) or UC with observation. The effectiveness of HCTR was assessed by changes in peak oxygen consumption (VO2 peak), workload duration (t) in cardiopulmonary exercise test and quality of life (QoL) based on Medical Outcome Survey Short Form 36 Questionnaire (SF-36). Measurements were made before and after intervention/observation. Results: Women constituted 11.5 % of population in the TELEREH-HF study. Forty women in HCTR group and 44 women in UC group completed HCTR and observation respectively. HCTR resulted in significant improvement in VO2peak, workload duration and QoL. We did not observe these favorable results in the UC group except for an increase workload duration. In the HCTR group, there was a significantly greater improvement in physical component of QoL than in the UC group. All results are presented in Table 1. In neither group were there deaths nor major adverse events related to exercise training. Conclusion In women with HF, hybrid comprehensive telerehabilitation is safe and resulted in a significant improvement in physical capacity and QoL.
