Study On The Effect Of Rehabilitation On Depression Anxiety Conditions And Heart Function In Coronary Artery Bypass Grafting Patients

ObjectiveTo observe the improved effect of rehabilitation on depression anxiety conditions and heart function in coronary artery bypass grafting patients.MethodsFifty-two patients who had to wait for coronary artery bypass grafting (CABG) in-hospital were randomly assigned to a cardiac rehabilitation (Rehab;n=27) or to usual care (Control; n=25). In the Rehab group, intervention was gradually increased movements and psychological intervention. Measurements:6 min walk test, Self-Rating Anxiety Scale(SAS), Self-Rating Depress Scale(SDS), Hmilton Anxiety Scale(HAMA), Self-Rating Depress Scale(HAMD), tumor necrosis factor-a (TNF-a), left ventricular ejection fraction(LVEF),length of ventilation with breathing machine, length of intensive care and post-operative length of stay (PLOS).ResultsCompared with control group, the postoperative scores of Self-Rating Anxiety Scale(SAS), Self-Rating Depress Scale(SDS), Hmilton Anxiety Scale(HAMA), Self-Rating Depress Scale(HAMD) were significantly dropped (P<0.01). Rehab patient's 6-min walk distance was significantly higher than control group (P<0.01). TNF-a level in rehabilitation group was decreased (P<0.01). The length of ventilation with breathing machine and length of intensive care after surgery was also reduced in the Rehab group (P<0.01). Rehab patient's postoperative left ventricular ejection fraction was improved compared with preoperative (P<0.01).Furthermore, the rehabilitation group showed respectively a positive correlation between SAS(r=0.46, P SDS(r=0.48,P<0.01),HAMA(r=0.53, P<0.01), HAMD(r=0.60, P<0.01) level and 6-min walk distance.ConclusionPsychological intervention combined with exercise training in patients after coronary artery bypass grafting may drop levels of anxiety and depression, improve exercise capacity, reduce risk factors of coronary heart disease, improve heart function.
