Abstract

This descriptive study aimed to investigate the relationship between cardiac rehabilitation behaviors and quality of life among patients post coronary artery bypass graft (CABG). The purposive sample consisted of 40 patients with CABG surgery of a tertiary Hospital in southern of Thailand, during 4 - 6 months post-operative. The data were collected by (1) the Demographic Data and Illness History Sheet, (2) the Cardiac Rehabilitation Behaviors for Patients Post-CABG Questionnaire, and (3) the Quality of Life for Patients Post-CABG Questionnaire, which were validated by three experts. The reliability of the cardiac rehabilitation behaviors questionnaire, andthe quality of life questionnaire were examined and yielded the Cronbach's alpha coefficient of .77 and 93 respectively. The data were analyzed using descriptive statistics, Pearson Product Moment Correlation, and Spearman Rank Correlation. The results showed that the mean score of total cardiac rehabilitation behaviors of the subjects was at a high level (M= 2.19, SD = 0.41). The mean score of cardiac rehabilitation behaviors related to life modification behaviors was highest (M = 2.57, SD = 0.29) following by, stress management (Mdn =2.38, IQR = 0.94), and exercise behaviors (M = 1.75, SD = 0.83). The mean score of the quality of life of the subjects was at a high level (M = 24.00, SD = 3.30). There were significantly positive correlation between the cardiac rehabilitation behaviors and the quality of life (r = .53, p< .001), and between exercise behaviors and the quality of life (r = .37, p< .05). These findings showed that the cardiac rehabilitation behaviors, particularly exercise had significant correlation with the quality of life. Therefore the cardiac rehabilitation behaviors should focus on continuing exercise, in addition symptom management should be promote for decreasing obstacle to perform cardiac rehabilitation behaviors in order to enhance quality of life of the coronary artery disease patients.
