The goal of this clinical trial is to examine in patients with acute coronary syndrome. The main questions it aims to answer are:

• Does nurse counseling affect quality of life?
• Does nurse counseling affect functional capacity?
• Does nurse counseling affect knowledge, attitudes and beliefs about syndromes?

Participants will be trained using the training booklet, and nursing counseling will then be provided for six months.

If there is a comparison group: Researchers will compare with the control group to see if the nurse counseling has had an effect.

After obtaining verbal and written consent from the participants, they are required to answer the questions on the Diagnosis Form, Acute Coronary Syndrome Response Index, and Multiple Quality of Life Scale. Then, preliminary measurements will be made and a 6-minute corridor walking test will be applied. While the control group will be followed up routinely, the training booklet prepared for the intervention group will be explained orally. Participants will then be informed that they will be called monthly. They will be told that they can reach these monthly calls and consult the nurse when they need it. After this stage, interviews with patients will begin. The standard way of communication with the participants by the researchers is by telephone, and a total of 6 interviews will be provided, the first of which is in the 1st month after the application of the tests. In each call, all the information in the training booklet will be repeated, additional information will be given in line with the needs and demands of the person, their questions will be answered and the interview will be ended. Although it varies according to the individual interviewed, it is predicted that these telephone interviews will last for 30 minutes on average. Apart from these standard calls, individuals in need will be able to reach the researcher face-to-face during phone calls, text messages, instant messaging methods or hospital visits, and in this way, the counseling process will continue actively for 6 months. After six months, the final tests will be done.
