The Effectiveness of Telehealth for Cardiac Symptom Distress, Self-care and Quality of Life of Patients With Coronary Artery Disease After Coronary Artery Bypass Surgery: A Randomized Study

The investigators scheduled telephone interviews every three days to encourage and monitor the development of good self-health care behaviors by: (1) asking about daily blood pressure, weight, and lower extremity edema; (2) providing medication counseling, as well as exercise and dietary hygiene recommendations; (3) offering wound care guidance; (4) advising on the proper use of wounds; (5) advising on avoiding cardiac risk factors such as smoking and secondhand smoke; and (6) following up on physical status at outpatient clinics and assisting with referrals to relevant clinics, such as nutrition or rehabilitation, based on the patient's condition. A QOCA portable electrocardiogram (ECG) measurement device will be provided for patients to use at home. In the event of abnormal physiological values, the investigator will contact the patient to assess his or her medical status and provide 24-hour online counseling.

Provide post-operative education on the day of discharge and follow up with a phone call one week after discharge to check on the patient.
