Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will engage in aerobic and resistance exercises tailored to accommodate sternal precautions. Each session begins with warm-up checks and personalized training tailored to the individual's baseline condition. The conditioning phase includes prolonged aerobic activity and progressive resistance training.

Each session is approximately 60 minutes in duration.

The exercise sessions are conducted in groups, with a staffing ratio of one instructor to every five participants.

Exercise intensity is individualized, beginning at low to moderate levels and progressing according to participant tolerance. The intensity is assessed using the Borg Category Scale, ranging from 'fairly light' (a perceived exertion level of about 13, 'somewhat hard') to 'hard' (15 on the Borg Scale) for those who can tolerate more vigorous activity. This assessment is complemented by monitoring heart rate responses and symptoms during exercise, conducted by exercise physiologists and physiotherapists specialized in cardiac rehabilitation.

Adherence to the intervention is monitored through documented attendance at each session, recorded in the hospital's electronic medical records.

Rehabilitation
Comparator / control treatment
The control group consists of patients who will receive usual care but choose not to participate in a structured cardiac rehabilitation (CR) program but agree to participate in the study. They will be given standard post-operative care instructions, which include general advice on gradual physical activity resumption and lifestyle modifications, but without the structured support and tailored interventions provided to the intervention group.

Efficacy
Statistical methods / analysis
The primary statistical approach for this trial will involve using descriptive statistics to summarise baseline characteristics and other demographic data. This will clearly understand the participant population and ensure valid comparisons between groups.
We will employ inferential statistics to analyse the primary efficacy parameters, such as DASI scores and QOLS changes. Comparative analyses between the intervention and control groups will be conducted using t-tests or ANOVA for continuous data, depending on the distribution of the data, and chi-square tests for categorical data. Additionally, we will utilise regression analysis to adjust for potential confounding variables and assess cardiac rehabilitation's independent effects on the outcomes. This will allow us to control for variables that could influence the results, such as age, baseline health status, and severity of cardiac disease.

For the intention-to-treat analysis, which includes all randomised participants regardless of protocol adherence, we will use techniques appropriate for dealing with missing data, such as multiple imputation. This analysis will ensure that our findings are robust and generalise to a broader patient population.

Summary
Brief summary
We are conducting a pilot study to see how well a cardiac rehabilitation program helps patients recover after open heart surgery. We will use the Duke Activity Status Index (DASI) tool to measure how much the program improves your ability to perform daily activities. This study aims to gather early information to understand how cardiac rehabilitation might help patients get better after their surgery.

We are also interested in learning about the recovery of patients who choose not to participate in a cardiac rehabilitation program. This will help us compare the outcomes of those who do and do not participate in the rehabilitation program.
