This randomized controlled trial evaluates a "Hospital-to-Home" self-management support model for Acute Coronary Syndrome (ACS) patients, which is based on the integrated COM-B and HAPA theories. Participants are randomly assigned to either an intervention group receiving a structured self-management program or a control group receiving standard education. The study compares self-management behaviors and health outcomes between the two groups to assess the model's effectiveness.

This intervention is based on the integrated HAPA and COM-B models. Using HAPA, patients are categorized into three phases: pre-action (contemplation), action initiation (early post-discharge), and behavior maintenance (≥1 month post-discharge). Prior to discharge, a COM-B assessment identifies individual barriers and facilitators across capability, opportunity, and motivation. Tailored self-management support is then delivered according to the patient's phase and COM-B profile. The core intervention consists of one in-depth inpatient interview and three outpatient sessions for self-management planning, execution, and confirmation.
Participants receive routine health education and standard care according to the hospital's standard clinical pathway for ACS patients. This includes basic discharge instructions, brochures on heart-healthy lifestyles, and routine outpatient follow-up appointments. No additional structured self-management support or extra telephone follow-ups are provided beyond standard care.

Heart Health Self-Efficacy and Self-Management Scale (HHSES) score
The Heart Health Self-Efficacy and Self-Management Scale (HHSES) is a 12-item instrument assessing participants' self-efficacy and self-management behaviors. Total scores range from 12 (minimum) to 48 (maximum), with higher scores indicating better self-efficacy and self-management. Scores ≥36 indicate high self-efficacy and self-management; 25-35 indicate a moderate level; and ≤24 indicate a low level. Administered at baseline and at 13, 36, and 60 weeks of follow-up.
Time frame: At baseline and at 13, 36, and 60 weeks of follow-up.
Incidence of major adverse cardiovascular events (MACE) including heart failure, angina, arrhythmia, and recurrent myocardial infarction
Major adverse cardiovascular events (MACE) is a composite outcome defined as the occurrence of heart failure, angina, arrhythmia, or recurrent myocardial infarction. Reported as number and proportion of participants experiencing any component event and/or the composite MACE. Assessed from the end of treatment through 60 weeks of follow-up.
Time frame: From the end of treatment through 60 weeks of follow-up
Emergency department visit rate for cardiac-related reasons
Proportion of participants with emergency department visits for cardiac-related reasons during the follow-up period. Calculated as (number of participants with cardiac-related emergency department visits ÷ total number of eligible participants at start of follow-up) × 100%. Assessed from the end of treatment through 60 weeks of follow-up.
Time frame: From the end of treatment through 60 weeks of follow-up
Social Support Rating Scale (SSRS) score
The Social Support Rating Scale (SSRS) is a 10-item instrument assessing social support along three dimensions: objective support, subjective support, and utilization of social support. Total scores range from 13 to 70. Scores \< 33 indicate low social support; 33-45 indicate moderate social support; and \> 45 indicate high social support. Assessed at baseline and at 13, 36, and 60 weeks of follow-up.

Chinese Version of the Brief Illness Perception Questionnaire (BIPQ) score
The Chinese Version of the Brief Illness Perception Questionnaire (BIPQ) is a 9-item instrument measuring illness perception. Total scores range from 0 (minimum) to 80 (maximum), with higher scores indicating worse/more negative illness perception (stronger perceived threat or more negative views toward the illness). Assessed at baseline and at 13, 36, and 60 weeks of follow-up.
Time frame: At baseline and at 13, 36, and 60 weeks of follow-up
Cardiovascular re-hospitalization rate
Proportion of participants re-hospitalized for cardiovascular reasons (e.g., heart failure, angina, arrhythmia, recurrent myocardial infarction) during the 12-month period after the end of treatment. Calculated as (number of participants re-hospitalized for ACS-related cardiovascular reasons during the follow-up period ÷ total number of eligible patients at the start of the follow-up period) × 100%. Assessed from the end of treatment through 60 weeks of follow-up.
Time frame: Assessed from the end of treatment through 60 weeks of follow-up.
Medication Adherence Report Scale (MARS-10) score
The Medication Adherence Report Scale (MARS-10) is a 10-item self-report questionnaire using a dichotomous yes/no response format. It evaluates medication adherence across three dimensions: medication adherence behavior, attitude toward taking medication, and negative side effects and attitudes toward medication. Total scores range from 0 to 10. A score ≤ 5 indicates medication non-adherence, and a score ≥ 6 indicates medication adherence. Assessed at 13, 36, and 60 weeks of follow-up.
Time frame: Assessed at 13, 36, and 60 weeks of follow-up.
