Plain English Summary

Background and study aims
Rehabilitation using the internet (telerehabilitation) has been proposed as an addition or alternative to standard cardiac rehabilitation (CR) to address the low use of standard CR programmes. The aim of this study is to test whether the addition of an internet cardiac telerehabilitation program to standard care improves long-term physical fitness in patients with heart disease.

Who can participate?
Men and women aged between 18 and 80 with heart disease (heart failure and diseases of the blood vessels supplying the heart muscle)

What does the study involve?
Half the patients receive standard CR and half receive standard CR and an internet telerehabilitation program (composed of physical activity monitoring and dietary, smoking cessation and activity coaching).

What are the possible benefits and risks of participating?
The possible benefits are an increase in physical fitness, improvements in risk factors that cause heart disease and reduction in the number of rehospitalisations. There are almost no risks.

Where is the study run from?
Three hospitals in Belgium: Jessa Hospital, Ziekenhuis Oost-Limburg and St Fransiscus Hospital

When is the study starting and how long is it expected to run for?
February 2013 to February 2015

Who is funding the study?
Flanders Care (Belgium) and Fonds Wetenschappelijk Onderzoek (Belgium)

Who is the main contact?
Prof. Paul Dendale

Coronary artery disease and heart failure


1. Patients in the intervention group were provided with an internet-based telerehabilitation program in addition to conventional centre-based cardiac rehabilitation. The telerehabilitation program was composed of physical activity telemonitoring (Yorbody accelerometer) and dietary, smoking cessation and activity telecoaching.
2. Study nurse led training was given to patients within 7 days after randomisation. They were provided with some background and general information about the study design, content and main hypotheses of Telerehab III. Patients were taught how to install the telerehabilitation program on their computer and use the motion sensor. This presentation was followed by a 1 hour practical training session in which patients were familiarised with the accelerometer and associated webpage. They were instructed on how to install the program at home; if they had questions and/or technical difficulties, they were provided with technical support.
3. Patients receiving the intervention were prescribed literature on patient-specific exercise training protocols, based on maximal cardiopulmonary exercise test and calculated body-mass index (BMI) at the start of the study. Patients with a high aerobic capacity (defined as peak oxygen consumption [VO2] of at least 80% predicted) were prescribed with exercise training at an intensity of at least 100 steps per minute, for at least three times per week and a minimum session of 30 minutes. The instructed volume of steps was set at 10000–12000 per day for patients with a BMI greater than 30 kg/m2 and 8000–10000 per day for patients with a BMI of less 30 kg/m2. Patients with a low aerobic capacity (defined as VO2 peak of less than 80% predicted) were allowed to choose the intensity of exercise sessions. The instructed volume of steps was again set at 10000–12000 steps per day for patients with a BMI of greater than 30 kg/m2 and 8000–10000 steps per day for patients with a BMI of less than 30 kg/m2.
4. Patients were instructed to wear the motion sensor during the whole study, except while bathing or sleeping. They uploaded data at least every 2 weeks to a secure webpage with an USB-connection because of the accelerometer’s storage capacity of 14 days. The webpage displayed uploaded physical activities, enabling patients to self-monitor these data. Based on the uploaded data, a semi-automatic telecoaching system provided patients with weekly feedback through e-mail or short message service (SMS) or both. The feedback was intended to encourage patients to achieve the goals as predefined in the patient-specific exercise training protocols.
5. Intervention patients were provided with weekly dietary advice, sent by email or SMS or both, according to the patients’ preferences. The dietary telecoaching program included a module for diabetes mellitus, arterial hypertension, obesity and healthy diet. Cardiovascular risk factor profiling at the start of the study determined which module(s) were prescribed for each patient. Key to the diabetes mellitus module was the restriction of fast carbohydrates, energy rich nutrition and ethanol containing beverages. The arterial hypertension and obesity modules focused on salt restriction and energy intake reduction, respectively. Healthy diet included recommendations based on the food triangle.
6. Patients in the control group received the conventional centre-based cardiac rehabilitation program; including 45 pluridisciplinary rehabilitation sessions focusing on healthy diet, psychosocial wellbeing, behavioural change, risk factor modification and exercise training. They were instructed to wear the accelerometer at the start of the study, after 6 weeks and at the end of the study for comparison purposes only. The sensors were taped, making it impossible to see the registered physical activity data. The study nurses at the respective hospitals uploaded the data; patients were not given any access to the webpage with uploaded data. The control patients did not receive any physical activity, smoking cessation or dietary telecoaching by email or SMS.
