Relationships of Factors Affecting Self-care Compliance in Acute Coronary Syndrome Patients Following Percutaneous Coronary Intervention

Abstract

Purpose: This study was conducted to identify direct and indirect factors influencing self-care compliance in patients with first acute coronary syndrome through examining the relationship among multidimensional factors.Methods: Outpatients who made hospital visits to receive a follow-up care at more than 6 months after percutaneous coronary intervention were recruited at a national university hospital in Korea. Data of 430 participants were collected through self-administered questionnaires and analyzed using AMOS version 7.0. The fitness of the hypothetical model and the degree of significance of direct and indirect paths were analyzed.Results: Three paths were found to have a significant effect on self-care compliance in the modified model. Social support indirectly influenced self-care compliance through enhancing self-efficacy, reducing anxiety and increasing perceived benefit. In addition, social support and body function indirectly influenced self-care compliance through reducing depression which affected self-efficacy. Selfefficacy was the most influential factor and played an important role as a mediating variable. Conclusion: Results of this study suggest that nurses’ counselling and education as a form of social support should be encouraged to enhance self-efficacy and self-care compliance among outpatients during follow-up care after percutaneous coronary intervention.
