Abstract
INTRODUCTION: Coronary artery bypass graft surgery is one of the most frequently performed surgical procedure. Supervised exercise programme have been recommended to facilitate recovery immediately after surgery. Cardiac rehabilitation is a widely accepted form of management for patient with cardiac disease. Cardiac rehabilitation is a process of restoring psychological, physical and social functions in people with manifestations of a coronary artery disease. In past 40 years there has been a profound shift from the conservative approach that discouraged physical activity in cardiac patients to one which encourage as much activity as the patients symptoms and medical status allow. In patients who have undergone a coronary artery bypass graft surgery, activities can decrease post surgical stiffness and prevent complications and decrease the incidence of severity of depression and anxiety and also improve self esteem. AIM OF THE STUDY: To assess the exercise heart rate & the level of rate of perceived exertion responses to aerobic exercise in post CABG individuals. NEED FOR THE STUDY: Coronary artery disease is the most common problem being faced by the people in the modern materialistic world. Exercise training increases cardio vascular functional capacity and decreases myocardial oxygen demand at any level of physical activity in apparently healthy persons and in most individuals with cardiovascular with cardiovascular disease. Regular aerobic exercise is required to maintain these training effects. The main aim of the study is to assess the exercise heart rate & the level of rate of perceived exertion responses to aerobic exercise training in post CABG individuals. METHODOLOGY: STUDY SETTING: The study was conducted in the out patient physical therapy department of Government Rajaji Hospital, Madurai. STUDY SAMPLE: Fifteen male CABG patients were selected by purposeful sampling method from Government Rajaji Hospital, Madurai. RESEARCH APPROACH: This study is a prospective study with an experimental same subject research design. CRITERIA FOR SELECTION: Inclusion Criteria: Asymptomatic low risk, uncomplicated male CABG individuals between age groups of 55 -70 years were included who are medically stable, uncomplicated and should have undergone traditional aerobic training for twelve weeks. Exclusion Criteria: Women and patients with the recent symptoms of angina or ischemia are excluded. Smokers and alcoholic patients, and patients with uncontrolled hypertension, dysrythrmias, congestive heart failure, moderate and high risk patients and with other complications are also excluded. RESULTS: Table 1 shows the comparison of exercise heart rate in the first training session to the last training session after 8 weeks. The mean value for exercise heart rate during first training session is noted 86.4, the standard deviation 3.807. The mean value for exercise heart rate during the last training session is noted 83.46, the standard deviation 3.544. The ‘t’ value was calculated to be at highly significant level 11 (P < 0.05). This suggests there is significant difference in exercise heart rate while comparing the first and the last training session. The Bar graph I shows the mean value for the exercise heart rate in the first training session and the mean value in the last training session. The mean value has a significant reduction from 86.4 in the first training session to 83.46 in the last training session. Table II shows the comparison of RPE level in the first training session to the RPE level in last training session after 8 weeks. The mean value for RPE level during the first training session is 12.06 and the standard deviation is noted to be 1.077. The mean value for RPE level during last training session is 9.93 and the standard deviation noted to be 1.06. CONCLUSION AND RECOMMENDATION: To conclude, the study showed that there was significant reduction in exercise heart rate and RPE levels responses when aerobic exercise training was given to post CABG individuals under going cardiac rehabilitation. There are various evidences that support the effectiveness of aerobic exercise training to post CABG patients. But the efficiency and safety benefits to women, older patients with low aerobic fitness, severe left ventricular dysfunction remain still unclear. Owing to lack of data unavailable, routine application of aerobic exercise training in moderate to high risk cardiac patients cannot be recommended at this time and requires additional study. Further studies can be done to analyse their effects also. This study was done by giving aerobic exercise training 8 weeks initially to produce moderate fatigue and further studies can be done with progressive time & speed used to train patients to volitional fatigue. The period of study is 8 weeks. It can also be aimed to increase the weeks also walking only prescribed other exercise are also included.
