Abstract

Background: Homed-based exercise training via telehealth is an effective method for cardiac rehabilitation in patients with heart failure (HF). However, little is known about the effects of telehealth exercise training among patients with HF in China.

Design: A randomized controlled design with repeated measures was adopted in this study.

Objective: To examine the effect of our telehealth exercise training program on health outcomes in patients with HF in China.

Methods: A total of 98 participants were randomly allocated to an experimental group (n = 49) and control group (n = 49) from January 2014 to February 2015 in a teaching hospital in Chengdu, People's Republic of China. Participants in the experimental group underwent an 8-week home-based telehealth exercise training program, including 32 exercise training sessions, with regular telephone or instant messaging follow-ups and consultations. Participants in the control group received usual care. The outcome variables used in this study were the Minnesota Living with Heart Failure Questionnaire, 6-minute walking distance (6MWD), resting heart rate (HR), Hospital Anxiety and Depression Scale, left ventricular ejection fraction (LVEF), and the New York Heart Association (NYHA) classification. Data were collected at baseline, post-test (2 months after discharge), and 4 months post-test (6 months after discharge). Repeated measures ANOVA was used to examine the effects of groups, changes over time, and interaction of time and group with the above variables.

Results: Statistically significant improvements were observed in the experimental group regarding quality of life (QOL) and 6MWD compared to the control group post-test. Significant improvements in QOL, 6MWD, and resting HR were sustained for 4 months post-test. However, no significant improvements were observed regarding the NYHA classification, LVEF, anxiety, and depression at either the post-test or 4-month post-test follow-ups. No patients experienced any significant complications or adverse outcomes during the program.

Conclusions: The results reveal that telehealth exercise training is an effective alternative method for cardiac rehabilitation, especially under the conditions in China.

Participant flow chat in this study. Simple randomization was used in this study. The 98 eligible patients were randomly assigned to either the experimental group (n = 49) or the control group (n = 49) prior to discharge by the researchers using a computer-generated random sequence. The patients in the control group received usual care without any type of instruction regarding exercise, while the patients in the experimental group received usual care plus telehealth exercise training. All patients in both the experimental and control group received a 4-month follow-up. A total of 83 participants completed the follow-up (42 in the experimental group and 41 in the control group).
