RESUMEN
To investigate the effect of education on the stress levels associated with Coronary Artery Bypass Graft [CABG] surgery in the week after CABG surgery. The study used a quasi-experimental design. Patients were selected through convenience sampling at a university hospital in Turkey. There were 60 patients in the study; 30 in the experimental group and another 30 in the control group. Data were collected using the Stressors Scale associated with CABG on the third day of the post-operative period. Cronbach's alpha of the scale was 0.89. Alpha coefficients ranged from 0.82 to 0.79.The difference between the score averages of the experimental and control group was p=0.002 for the illness-related subscale, p=0.031 for the hospital related subscale, and p=0.006 in total. Education was effective for reduction of stress associated with CABG surgery
