ABSTRACT
Objective: To find out and Compare the Combined effect of Aerobic interval training with Conventional cardiac rehabilitation over Conventional cardiac rehabilitation alone on endurance capacity and quality of life after Coronary Revascularization.
Background: Coronary artery disease commonly affects the coronary arteries of the heart. Various studies revealed that there is change in quality of life in CABG patients. Physiotherapy intervention needs to be targeted according to the postoperative complications like airway clearance techniques or strengthening the respiratory muscles, etc. Apart from conventional physiotherapy treatment, aiming to re-establish endurance capacity and quality of life, some strategies such as aerobic interval training should be used which will improve endurance capacity. This Present study is focused to determine whether the combined administration of Aerobic exercise training with conventional cardiac rehabilitation has more benefits in comparison with conventional cardiac rehabilitation
Methodology: A Pretest Posttest Experimental Design was used to conduct a 4 week duration interventional study. A total of 30 patients were selected based on the selection criteria and divided into two groups. Each group consisted of (n=15) members. The sample selection was done using random sampling method after due consideration of inclusion and exclusion criteria. Group A received both Aerobic exercise training and conventional cardiac rehabilitation and Group B receives only Conventional cardiac rehabilitation. Six minute walk test and Macnew Questionnaire were used as outcome measure for endurance capacity and quality of life respectively. The Effective training method is identified with appropriate statistical method.
Results: The comparison of post-test values of Six Minute Walk Test between Group – A and Group - B showed that the calculated‘t’ value 9.84 which is greater than the tabulated t value 2.048 at 5% level of significance. This shows that there is a significant improvement on Endurance Capacity in Group A than Group B following treatment. The comparison of post-test values of MacNew questionnaire between Group - A and Group - B showed that the calculated‘t’ value 15.89 which is greater than the tabulated ‘t’ value 2.048 at 5% level of significance. This shows that there is a significant improvement on Quality of Life in Group A than Group B following treatment.
Conclusion: This study concluded that aerobic interval training when added to conventional physiotherapy program proved to be significantly effective in improving endurance capacity and quality of life as compared to conventional cardiac rehabilitation alone after Coronary Revascularization.
