Background and purpose: Cardiovascular disease is the main cause of death in the world, including Iran. Cardiac rehabilitation is associated with improving patients' performance and reducing mortality from all causes of death. This study aimed to investigate the changes in exercise capacity and hemodynamic factors following cardiac rehabilitation in patients referred to the cardiac rehabilitation department of Mazandaran Heart Center. Materials and methods: This cross-sectional study was carried out by examining the medical records of 262 patients referred between February 2018 to February 2020. Each of the three groups of patients with coronary artery disease, valvular heart disease, and chronic heart failure were separately examined in terms of values before and after cardiac rehabilitation related to systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and resting heart rate (HR). Data were analyzed with SPSS-22, STAT-15 software. Results: In each of the three mentioned groups of cardiac patients, the mean SBP, DBP, and MAP variables had a significant decrease (P0.2). Conclusion: Cardiac rehabilitation may improve exercise capacity and hemodynamic factors, including SBP, DBP, and MAP in patients with various heart diseases and is recommended as a class І suggestion in eligible patients.

Introduction: COVID19 is an acute respiratory syndrome that affects the immune system. Obesity can increase the risk of developing this disease. The aim of this study was to evaluate the prevalence of COVID-19 in female students based on their body mass index (BMI) and waist-hip ratio (WHR). Methods: 700 girl students aged 15-18 years in Neyshabur City, Iran were selected by simple random sampling and divided into two groups: the healthy (n=519) and Corona (n=181). The results were analyzed using non-parametric statistical tests of Mann-Whitney U Test, Spearman correlation coefficient and two-point string test at a significance level of p≥0.05. Results: In the healthy group, the mean of BMI was 21.09±3.4, WHR 0.77±0.07, and age 16.53±1 years and in the Corona group, the mean of BMI was 22.32±4.11, WHR 0.77±0.06 and age was 16.80±0.89 years, respectively. The results of the Mann-Whitney U test in the BMI of the two groups were significantly different (P = 0.001). Abdominal obesity was not significant in both groups (P = 0.469). There was a significant positive relationship between BMI and WHR (P = 0.00094). There was a significant relationship between BMI and Corona using the agreement coefficient with the two-point string test (P = 0.001). Also, the results of the Mann-Whitney U test showed that the resting heart rate of the two groups was significantly different (P = 0.026). Conclusion: The results of the present study showed that in adolescents, increasing BMI and resting heart rate increases the prevalence of Corona disease and abdominal obesity has no effect on corona virus infection. Therefore, due to the effect of exercise activities on losing weight and resting heart rate, the need to do these activities during quarantine is considered.

Background and Objectives Menopause is associated with cardiovascular complications. The present study aimed to determine the effect of eight weeks of aerobic exercise and soybean consumption on cardiovascular function in postmenopausal women. Subjects and Methods In this semi-experimental research, 60 postmenopausal women living in Andimshek City, Khuzestan province, Iran, were selected by purposeful sampling and then randomly divided into four groups: 1) soy (n=15), 2) exercise (n=15), 3) combined (exercise+soy, n=15), and 4) control (n=15 people). The exercise intervention consisted of eight weeks of exercises, three sessions per week with an intensity of 50-70% of heart rate reserve. Soy consumption was 80 g of soybeans daily. Paired sample t-tests and covariance analysis were used for statistical analysis, and the significance level was considered p ≥ 0.05. Results A significant decrease in systolic blood pressure, diastolic blood pressure, and resting heart rate was observed in the aerobic and combined exercise groups compared to the control group (P<0.01). A significant decrease in systolic blood pressure was also observed in the soy group compared to the control group (P<0.001). Moreover, the decrease in resting heart rate was significantly higher in the aerobic and combined exercise groups than in the soy group (P<0.001). Conclusion According to the results, it can be said that aerobic exercises and the consumption of nuts have positive effects on improving cardiovascular function in postmenopausal women, and the use of both boosts effectiveness in cardiovascular protection.

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.
