Abstract

background and aim:Cardiovascular disease is leading cause of mortality and morbidity in the world, there is lack of scientific evidence in high risk cardiac patients. The aim of present study was to investigate the effects of CR program on high risk cardiac patients in Iran.Materials and Methods: 40 high risk cardiac patients (mean age 61.40± 6.09) who had coronary artery bypass grafting (CABG) participated in phase III exercise cardiac rehabilitation. Participants were randomly divided in two groups which one group completed 4 weeks CR while other group participated in 8 weeks CR program. All patients underwent exercise testing before and after CR program. Completed Quality of Life (QLMI) questionnaire, Anxiety and Depression scale (HADs) at baseline and end of CR program. Results:Statistical analysis indicated that the exercise capacity, quality of life, anxiety and depression in both groups significantly improved after 4 and 8 weeks CR program. there were significant differences between two groups in exercise capacity (p<0/001), quality of life (p<0/001) anxiety and (p<0/008) depression (p<0/029), as patients who completed 8 weeks CR get more benefits than patients who completed 4 weeks CR program. It is concluded that the CR program is a safe and beneficial effects in all high risk CABG patients (both groups). Conclusion:Based on findings of presents study as patients who completed 8 weeks program get more benefits than other group it is recommend that the 8 weeks CR program is more beneficial for high risk cardiac patients. Therefore, it is suggested to refer all high risk patients to 8 CR program.
