Experimental: Patients in the experimental group will be given animation-based video training with a laptop one day before the surgery. The animation-based video training lasts 8 minutes and 35 seconds in total.

Patient Information Form, Self-Care Management in Chronic Diseases Scale, Visual Analog Scale, Hospital Anxiety Depression Scale, Surgical Fear Scale (Turkish Version) will be applied.

Control: In the preoperative period, no training will be given by the researcher to the patients constituting the control group. Patients in this group will receive the routine training of the clinic before surgery. Patient Information Form, Self-Care Management in Chronic Diseases Scale, Visual Analog Scale, Hospital Anxiety Depression Scale, Surgical Fear Scale (Turkish Version) will be applied.

animation-based education for elderly patients before coronary artery bypass graft surgery Before coronary artery bypass graft surgery, the scenario prepared based on the literature information including introduction of the service, preparation for surgery, monitoring, drug treatment and applications, deep breathing and cough exercise, spirometer use, operation time, postoperative period and care, patient pain management and intubation process will be given as animation-based video training. The effects of this on postoperative pain, fear, anxiety and self-care management will be evaluated.

The personal information form used for data collection consists of demographic characteristics of the individuals such as age, gender, marital status, occupation, educational status, employment status, as well as questions including health-related conditions of the patients such as chronic diseases, whether they have had surgery before or not.

Self-Care Management-Protection (SCMP-G) After Jones and Preuett defined the concept of self-care management process (SCMP), the validity of SCMP was tested and the characteristics of the protection concept were explained and added.While developing the SCMP-G scale, two types of protection concepts were defined.These concepts were determined as self-protection and social protection and formed two sub-dimensions of the scale. The self-protection sub-dimension consists of items numbered 2, 6, 8, 11, 15, 18, 19, 20, 22, 23 and 25-34, while the social protection sub-dimension consists of items numbered 1, 3-5, 7, 9, 10, 12-14, 16, 17, 21, 24 and 35.The scale has a format that is evaluated between 5 (Strongly Agree) and 1 (Strongly Disagree).The higher the score, the higher the level of self-care management.The Cronbach's Alpha of the self-care management scale in chronic patients is 0.85. The Cronbach's Alpha for this study was 0.89.

The Hospital Anxiety and Depression Scale is a scale consisting of a total of 14 items. Odd numbered items assess anxiety and even numbered items assess depression. The scale has a four-point Likert-type structure and the score range of the items is between 0 and 3. The total scores of the subscales are calculated by summing the scores of the related items. To calculate the anxiety subscale score, the scores of the 1st, 3rd, 5th, 7th, 7th, 9th, 11th and 13th items should be summed, while the scores of the 2nd, 4th, 6th, 8th, 10th, 12th and 14th items should be summed for the depression subscale score. Individuals who score above these cut-off points should be considered in the risk group. The Cronbach's Alpha of the scale is 0.81. The Cronbach's Alpha of this study was 0.89.
