Background & Aims: Cardiovascular diseases are the main cause of death worldwide. Globally, 30% of deaths (approximately 17 million deaths per year) are attributable to cardiovascular diseases. In 2006 alone, the estimated total direct and indirect costs associated with the treatment of cardiovascular diseases exceeded 400 billion dollars. Currently, in Iran, insurance organizations only bear a limited part of cardiac rehabilitation costs, while taking into account the impact of these programs in secondary prevention and reducing the incidence of cardiovascular events and as a result reducing the treatment costs imposed on this Organizations will focus on covering cardiac rehabilitation programs both for the benefit of the patient and for the benefit of the insurance organizations. According to the mentioned studies and many other studies and the high and increasing prevalence of cardiovascular diseases in Iran, and on the other hand, the clinical advantages of cardiac rehabilitation in coronary artery transplant patients, including secondary prevention and preventing disease recurrence and improving the quality of life, are necessary and The importance of this research is clear. Cardiovascular diseases are the main cause of death all over the world, so the purpose of this study is to investigate the effect of eight weeks of cardiac rehabilitation on the functional indices of systolic and diastolic blood pressure, resting heart rate, vo2max and MEt functional capacity in male patients 55 Coronary artery transplant surgery up to 70 years old.
Methods: The research method is semi-experimental with a pre-test and post-test design. The statistical population of this research consisted of 120 male coronary artery transplant patients aged 55 to 70 years who referred to the Sari Heart Center. The statistical sample included 40 people who lived in Sari city and underwent coronary artery transplant surgery for at least 2 months and at most 4 months. Then they were randomly and equally divided into 2 groups of 20 people, control and therapeutic intervention of cardio sports rehabilitation. In this research, in order to measure the resting heart rate HR H before the test of two control and cardio exercise rehabilitation groups, therefore the best time to determine the heart rate in the morning after waking up is one hour after breakfast and without intense physical activity in a state of rest. For 20 minutes, the subjects of the two groups sat on a chair and were measured. All the subjects were advised to sleep early the night before and avoid any kind of stress. The systolic and diastolic blood pressures of the two groups were measured before the test using a dial sphygmomanometer. The time of assessment was two hours after breakfast, and the subjects were advised to refrain from smoking, vigorous physical activity, and drinking for one hour before any use of cigarettes. Avoid coffee and caffeinated drinks and sit quietly for 20 minutes and wear comfortable clothes. 12 hours before the test, blood lipid profile was taken from the subjects of both the control and cardiac rehabilitation groups fasting. The sample required for the test was 10 cc from the brachial vein immediately without delay for the actual values ​​after lying on the bed. 24 hours. Before the test, in consultation with a cardiologist, reduce the dose of heart and blood pressure medications such as Inderal and Atenolol. Also, asthmatic patients should carry a special spray and wear comfortable clothes and shoes for the test, and avoid caffeinated drinks and cigarettes 24 hours before. Cardio sports rehabilitation program consisted of 24 sessions 3 days a week for 2 months, which included 15 minutes of warm-up, 30 minutes of treadmill and 20 minutes of stationary bike, and 20 minutes of stationary bike and 15 minutes of cooling down. To investigate and compare pre-test and post-test variables between two groups, independent parametric t-test was used. Data analysis was done using spss software. The significance level was p<0.5.
Results: The results showed that eight weeks of cardiac rehabilitation has an effect on the improvement of systolic blood pressure (SBP), diastolic blood pressure (DBP), improvement of heart rate and improvement of vo2max and MEt functional capacity in male patients aged 55 to 70 undergoing coronary artery bypass surgery.
Conclusion: The findings of the current research have shown the effect of a cardiac rehabilitation course on the improvement of hemodynamic indicators and functional capacity, considering the high prevalence of cardiovascular diseases in the country, and on the other hand, the high per capita consumption of drugs and their high costs, and the high importance of cardiac sports rehabilitation in improving The quality of life of heart patients, including coronary artery transplantation, is necessary and necessary to pay more attention to the category of cardiac rehabilitation and to build clinics and centers for it. The findings showed that cardio sports rehabilitation reduces the risk of coronary atherosclerosis by improving heart rate and as a result of heart attack and ischemic diseases. In order to control the risk factors of systolic and diastolic blood pressure in patients who have undergone coronary artery bypass graft surgery (CABG), it is suggested to periodically use cardiac rehabilitation programs for their treatment.
