Objective: Coronary Artery Disease is a chronic and complex disease requiring continuous medical care. The current study was conducted to for predicting Health-Related Quality of Life based on Emotion Regulation with mediating to Self-Care in Patients with Coronary Artery Disease (CAD). Methods: The research method was a descriptive study and correlation type. The statistical population comprised all patients with CAD (N=350) referring to Shohadaye Tajrish Hospital in Tehran, Iran, in the second half of 2020. Based on the Tabachnick Fidell formula, 184 subjects were selected using a convenient sampling method. Research instruments were the Self-Care Scale (Jaarsma, Halfens, Tan & et al, 2003), Emotion Regulation Questionnaire of Garnefski & Graich, 2001), and HRQol Survey (Ware, Kosinski, Keller, 1996). Data analysis was done using Structural Equation Modeling (SEM) and path analysis. Results: The data indicated a positive and significant mediating role of self-care in the relationship between emotion regulation (β= 0.175, p<0.01) and HRQoL of patients with CAD. Moreover, self-care and emotion regulation had a positive impact on HRQoL. Conclusion: According to findings, a part of the mutual effect of self-efficacy and emotion regulation on HRQoL is explained by self-care. On the other hand, high emotion regulation, and self-care led to better HLQoL of CAD patients.
