Coronary artery bypass graft surgery [CABG] improves the quality of life, increases survival, and influences the patient’s mental and emotional aspects. Little information is available on the lived experience of Iranian patients after this surgery. Understanding the lived experiences of patients will help health professionals with better provision of high quality care. This hermeneutic phenomenological study aimed to understand the lived experience of patients after CABG. Van Manen’s method was used to conduct the study. A semi-structured, face-to-face interview technique was employed to explore the experiences of the patients following surgery. Seven men and 4 women between 49 and 80 years old were interviewed. Passion for life was the main theme extracted from the participants’ interviews. This theme comprised the three sub-themes of receiving attention from family, being hopeful, and being spiritually oriented. The results showed that the participants experienced passion for life after their surgery. This finding reveals that patients tend to find a new perspective on life and their health after surgery
