EVALUATION OF COMPLEX STROOP PERFORMANCE OF PATIENTS (CABG), WITHIN THE FIRST YEAR AFTER SURGERY

Previous studies have provided contradictory results about attention performance after the coronary artery bypass graft (CABG). With regard to the importance and direct effects of attention strength on the quality of life, this research was designed and conducted to study the complex stroop performance of young patients who underwent CABG one year after surgery.

This causal-comparative study was conducted from February 2017 to October 2018. Two groups of individuals, 40 (CABG) male patients within the age range of 30 to 55 years old who were admitted to the ICU in Tehran Heart Center and 64 healthy menparticipated in the study. Both groups were tested with scale complex Stroop.

The results showed that two groups were significantly different(p<0/01) in the power of attention test, the congruent experiment time, incongruent experiment time, congruent reaction time, and incongruent reaction time. Also the two groups were significantly different (p<0/05), in the scores of incongruent non-responses, incongruent correct number, and interference score. The results showed that patients who underwent CABG have overall poorer results for all the scales of stroop test than healthy subjects.

According to the findings of this study, CABG can disturb cognitive functions of the prefrontal lobes in brain after one year. Hence, it is suggested to consider this issue in clinical evaluations of the patients.
