Introduction: Coronary heart disease (CHD) is the leading cause of death globally, and e-health educational programs have been
proved to be an effective support to patients. Considering the advantages of e-health programs, as well as the growing number of
young patients with CHD in Hong Kong, we plan to conduct a randomized controlled trial (RCT) to investigate the effectiveness
of a home-based interactive e-health educational intervention for patients with CHD in terms of improvements in total physical
exercise, exercise adherence and self-efficacy, risk factor profile, psychological outcomes, and quality of life.
Methods & Analysis: The RCT will be conducted in two government cardiac clinics in Hong Kong. Using a block randomization
method, 438 eligible CHD clients will be randomly categorized to either the control group or the intervention group. All participants
will receive usual care, but those in the intervention group will additionally receive the e-health educational intervention program.
This program will consist of a one-hour educational session, one telephone follow up, and an e-health link on self-monitoring,
which includes the recording of health measures and physical exercise across six months. Data will be collected at baseline, three-,
and six-month intervals. The primary outcomes will be total physical exercise, which will be measured by the Godin–Shephard
Leisure-Time Physical Activity Questionnaire. The secondary outcomes will consist of exercise efficacy and adherence rate, CVD
risk profile, physical and psychological health outcomes (as measured by the Chinese version of the Health Survey Questionnaire
and Hospital Anxiety and Depression Scale), and biological parameter. The data will be analyzed using mixed effect models and
confirmatory factor analysis.
Ethics & Dissemination: The study complies with the Declaration of Helsinki and was approved by the University and Hospital
Ethics Committee. The findings will be disseminated in international conferences and publications.
