Brief summary
Objective: This study aimed to retrospectively evaluate the impact of cardiac rehabilitation (CR) on functional capacity, depressive symptoms, and the quality of life and sleep in patients with heart disease. Methods: A retrospective analysis was conducted on patients who participated in a structured CR program. Clinical records were reviewed to compare pre- and post-rehabilitation outcomes. Functional capacity was assessed using the 6-Minute Walk Test (6MWT), while depressive symptoms, health-related quality of life, and sleep quality were evaluated using the Beck Depression Inventory (BDI), the Short Form-36 (SF-36), and the Pittsburgh Sleep Quality Index (PSQI), respectively.
Interventions
The intervention consists of a structured, exercise-based cardiac rehabilitation (CR) program. The exercise protocol was tailored to each patient's clinical status and typically included aerobic endurance training complemented by resistance training for major muscle groups. Each session lasted approximately 40-60 minutes, consisting of a 10-minute warm-up, 20-40 minutes of moderate-intensity aerobic activity or high-intensity interval training (1:1 ratio), and a 10-minute cool-down period.

Inclusion criteria
* Patients diagnosed with coronary artery disease (CAD), status post-myocardial infarction (MI), stable angina, or those who have undergone cardiac surgery * Availability of complete pre- and post-rehabilitation clinical records, including 6-Minute Walk Test (6MWT), BDI, SF-36, and PSQI scores. * Patients classified as stable by a cardiologist prior to the initiation of the exercise program.
Exclusion criteria
* Presence of severe orthopedic, neurological, or musculoskeletal disorders that prevent the performance of the 6-Minute Walk Test or exercise training. * Patients with severe cognitive impairment * Unstable angina pectoris, uncontrolled arrhythmias, or advanced heart failure (NYHA Class IV) that contraindicates aerobic exercise. * Patients who dropped out of the rehabilitation program before completion or had more than a 20% absence rate in sessions. * Patients who underwent major non-cardiac surgery within the last 3 months.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional Capacity | Baseline and and post-intervention (6 week later) | unctional capacity is assessed using the 6-Minute Walk Test (6MWT). The distance walked in 6 minutes is recorded in meters. An increase in distance indicates improved functional exercise capacity. |
| Change in Depressive Symptom | Baseline and and post-intervention (6 week later) | Assessed using the Beck Depression Inventory (BDI). The BDI is a 21-item self-report scale. Scores range from 0 to 63, where higher scores indicate more severe depressive symptoms. |
| Change in Quality of Life | Baseline and and post-intervention (6 week later) | Assessed using the Short Form-36 (SF-36) Health Survey. It consists of 36 items covering 8 dimensions of health. Scores range from 0 to 100 for each subscale, with higher scores representing better health status. |
| Change in Sleep Quality | Baseline and and post-intervention (6 week later) | Assessed using the Pittsburgh Sleep Quality Index (PSQI). The PSQI consists of 19 individual items generating 7 component scores. The global score ranges from 0 to 21; higher scores indicate poorer sleep quality (scores \>5 suggest significant sleep disturbance). |
