Abstract
Phase one cardiac rehabilitation is important for patients with acute myocardial infarction .Critical care nurses play an important role on relieving pain, improving respiratory distress , maintaining adequate tissue perfusion by decreasing the heart work load, and early recognition of complications. Aim: to evaluate the effect of phase one cardiac rehabilitation on occurrence of early complications among acute myocardial infarction patients with ST segment- elevation. Patient and methods. Design: a quasi-experimental research design is used in this study. Setting: this study is conducted in the coronary care unit, Assiut University Hospital. Sample: a convenience sample of 60 patients (control and study) 30 each .Tools: Three tools are used for data collection. I –Acute myocardial infarction patient assessment, II- modified Borg's rating perceived exertion Scale , III -Hospital anxiety and depression scale . Methods: training the patient up to a heart rate of 120 beats / minute or peak heart rate, guided by symptoms of chest pain and dyspnea (Borg's rating of perceived exertion < 10 ) for the study group were performed for 5-days during phase one cardiac rehabilitation, Hospital anxiety and depression scale was applied tool for both groups. Results: findings of the present study show significant difference recurrence of chest pain was between both groups in 4th day .Also the duration of chest pain per hr in the 2 nd day & 3 rd day between both groups indicates highly statistical significant difference ( p < 0.05) ,and improve Heart rate, respiratory rate & decrease anxiety from 3 rd to 5 th day in the study group than control group, also shows Borg's (RPE) scale shows highly significant increased in study group during exercise from admission to 5th day. Conclusion: phase one cardiac rehabilitation is associated with significant improvement of the study group versus control group regarding for dyspnea, heart rate, chest pain, anxiety and depression.
