Investigation of Changes in Hemodynamic Factors Following Cardiac Rehabilitation in Patients Referred to Cardiac Rehabilitation Department of Mazandaran Heart Center

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.
