            This predictive research was conducted to study cardiac rehabilitation adherence and its influencing factors among coronary artery disease patients who underwent coronary artery bypass graft surgery for 3 - 12 months. One hundred eight participants were recruited using simple random sampling from the outpatient department of hospitals under the Ministry of Defense in Bangkok. Data were collected from August to November 2021. Research instruments consisted of the demographic data record form, the Charlson comorbidity index, 12-item short form health survey, perceived barriers to cardiac rehabilitation questionnaire, family support questionnaires, and adherence to cardiac rehabilitation questionnaires. Data were analyzed using descriptive statistics and multiple regression analysis.
            The results showed that the participants had a relatively high mean of adherence to cardiac rehabilitation (Mean = 42.35, SD = 4.75). Perceptions of health together with perceived barriers to cardiac rehabilitation and family support could explain total variance of 31 % (Adjusted R2 = .31, p < .001) for adherence to cardiac rehabilitation. Meanwhile, co-morbidities had no significant influence on adherence to cardiac rehabilitation. The findings suggest that nurses should develop a program or guideline to promote adherence to cardiac rehabilitation on patients undergoing coronary artery bypass graft surgery by promoting their appropriate health perceptions and the care from family support depending on their cardiac rehabilitation barriers for preventing recurrent coronary artery disease.
