What this trial studies

This study aims to evaluate the combined effects of the 4-7-8 breathing technique and stationary cycling on physical performance, quality of life, and dyspnea in patients recovering from coronary artery bypass grafting (CABG). A total of 58 post-CABG patients will be randomly assigned to two groups: one receiving both the breathing technique and cycling, and the other receiving only cycling. The intervention will consist of 18 exercise sessions per month, and outcomes will be measured using the 6-minute walk test, SF-36 questionnaire, and modified Borg scale. Data analysis will be conducted using SPSS to assess the effectiveness of the interventions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 to 70 who have successfully undergone CABG and are in stable condition.

Not a fit: Patients with severe comorbidities or those unable to perform physical activities will likely not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance recovery and quality of life for patients after CABG surgery.

How similar studies have performed: While similar approaches have been explored, this specific combination of interventions is relatively novel and has not been extensively tested.
