The effect of cardiac rehabilitation on hemodynamic parameters in patients undergoing coronary artery bypass surgery

The aim of this study was to evaluate the impact of cardiac rehabilitation on hemodynamic parameters in patients undergoing coronary artery bypass graft surgery (CABG). Nowadays، CABG is common to treat complications of cardiovascular disease in many patients. This clinical trial study was conducted on 50 patients after CABG. The patients were selected based on objective and with regard to the inclusion criteria. Rehabilitation program was conducted for 24 sessions. Data were collected by demographic questionnaire and hemodynamic parameters checklist at the beginning of rehabilitation، 12th session and 24th session of cardiac rehabilitation. The data were analyzed by using Chi-square، RMANOVA tests and SPSS software. The groups in terms of demographic variables were not significantly different with each other. The findings showed statistically significant differences in variables such as systolic blood pressure، pulse rate and arterial hemoglobin saturation. There were significant differences in these variables between the first and the last sessions (session 24)، also between the first session and during the rehabilitation (session 12). There was a significant difference between the 12th and the end of rehabilitation (session 24) in the diastolic blood pressure (p=0. 045)، but no significant differences in other hemodynamic parameters were seen. The results indicate a relative improvement in some hemodynamic parameters with cardiac rehabilitation intervention; therefore، it is necessary to pay more attention to the cardiacrehabilitation.
