Background: Exercise training has been shown to modify the sympathovagal control of heart rate toward an increase in parasympathetic tone. At the same time, the improved vagal activity is associated with reduced death risk from cardiac events (Wu S-K, Lin Y-W et al). Although a cardiac rehabilitation exercise program is standard therapy for patients after a cardiac event and especially for those who have received Coronary artery bypass grafting (CABG), the relationship between a cardiac rehabilitation exercise programme and acute hemodynamics and comparison with home based exercise programme has not been clearly demonstrated. Objectives: To find the effect of cardiac rehabilitation and home exercises on blood pressure, Heart rate, Respiratory Rate and Rating of perceived exertion (RPE) and compare the effects of cardiac rehabilitation and home exercises. Method: Thirty consecutive eligible patients undergone Coronary artery bypass grafting (CABG) referred by cardiovascular surgeons had participated in this study. After completion of baseline exercise stress test at discharge or within first week after discharge were randomly assigned to group A (Hospital based Cardiac rehabilitation) and group B (Home based cardiac rehabilitation) for 6 weeks. Materials: Perceived exertion scale, Stop watch, Blood Pressure apparatus, Pulse oxymeter Result: There were significant improvements in hemodynamics (p=0.000) both with hospital based cardiac rehabilitation and home based exercises but there were no significant differences between hospital cardiac rehabilitation and home based exercises. Conclusion: This study had concluded that both hospital based cardiac rehabilitation and home based exercises are effective in improving acute hemodynamics.
