简要总结
Objective: This study aimed to retrospectively evaluate the impact of cardiac rehabilitation (CR) on functional capacity, depressive symptoms, health-related quality of life, and sleep quality 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.
详细描述
Background and Rationale:Cardiovascular diseases remain a leading cause of morbidity and mortality worldwide. Comprehensive cardiac rehabilitation (CR) programs are widely recognized as a cornerstone of secondary prevention, aiming to improve physical fitness, psychological well-being, and overall health status in cardiac patients. However, real-world retrospective data assessing the multi-dimensional impact of structured CR-encompassing functional capacity, psychological distress (depressive symptoms), health-related quality of life, and sleep quality-simultaneously remain crucial for optimizing patient care protocols.
Study Objectives:The primary objective of this retrospective study is to evaluate the changes in clinical, functional, and psychosocial outcomes following participation in a structured cardiac rehabilitation program. Specifically, the study aims to compare pre- and post-rehabilitation measures regarding: Functional exercise capacity, depressive symptom severity, health-related quality of life (HRQoL), sleep quality.
Study Design and Patient Population:This study utilizes a retrospective observational design. Clinical records and institutional databases will be systematically reviewed to identify patients with heart disease who were admitted to and completed a structured cardiac rehabilitation program.
Data Collection and Outcome Measures: All patient data regarding baseline characteristics, clinical history, and pre- and post-rehabilitation assessments are routinely collected as part of standard clinical care. The primary and secondary outcome measures to be extracted and analyzed include:
- Functional Capacity: Assessed using the 6-Minute Walk Test (6MWT), measuring the distance walked in 6 minutes as an indicator of submaximal aerobic capacity.
- Depressive Symptoms: Evaluated via the Beck Depression Inventory (BDI), a self-report questionnaire measuring the severity of depression.
- Health-Related Quality of Life (HRQoL): Evaluated using the Short Form-36 (SF-36) health survey, covering both physical and mental component summaries.
- Sleep Quality: Assessed using the Pittsburgh Sleep Quality Index (PSQI), measuring sleep habits and disturbances over a 1-month time interval.

研究组 & 干预措施
Cardiac Rehabilitation Group
Patients in this group participated in a structured, multidisciplinary cardiac rehabilitation program. The intervention included individualized aerobic exercise training, resistance exercises, patient education, and psychosocial counseling.
干预措施: Exercise Based Cardiac Rehabilitation (Other)
结局指标
主要结局
Functional Capacity
时间窗: Baseline 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
时间窗: Baseline 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
时间窗: Baseline 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
时间窗: Baseline 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).
