The Comparing of brain/behavioral systems in patients before and after open heart surgery

The aim of this study is to compare the brain-behavioral systems in people before and after open-heart surgery.The present research is a descriptive study with a comparative and retrospective causal method with purposeful sampling. The statistical population of the study includes 210 people, encompassing 70 people who underwent open-heart surgery, 70 volunteered for open-heart surgery and 70 other with a history of heart diseases. the information was collected in addition to the demographic questionnaire through the Gray-Wilson personality questionnaire. Then, in order to analyze the collected data, statistical models of multivariate and univariate analysis of variance were used. The results showed that, patients candidate for open-heart surgery scored higher than patients who underwent surgery and the control group in behavioral activation measure. According to the findings in the behavioral inhibition component, there is a significant difference between the three groups. Patients who underwent surgery received the minimum scores in active avoidance, further people who underwent open-heart surgery received lower scores than patients who were candidate for surgery and the control group in extinction measurement.Therefore, due to the decrease in the performance of the behavioral activation system and the increase in the performance of the behavioral inhibition system, behavioral-activation-based interventions under the supervision of psychologists should be planned and implemented for these patients.
