BackgroundSelf-care refers to the conscious actions and behaviors that patients engage in to maintain and promote their own health and to the decisions that they make about managing signs or symptoms. Despite the importance of self-care in improving the health status of patients with cardiovascular disease, such as those undergoing angioplasty, these patients do not implement self-care optimally. This study aimed to identify factors affecting self-care behaviors in cardiac patients undergoing angioplasty based on a health-promotion model.MethodsA cross-sectional study was conducted among 200 cardiovascular patients undergoing angioplasty referred to the Bushehr Health Center. Health-promotion-model constructs and self-care behaviors were assessed by a researcher-made questionnaire. Data were analyzed by SPSS version 22 using multiple linear regression analyses.ResultsStepwise regression revealed that three variables - perceived barriers, perceived self-efficacy, and social support - were significant predictors of self-care behaviors among patients undergoing angioplasty. These factors accounted for 43.1% (R 2=0.431) of variance in self-care. Among the health-promotion-model constructs, self-efficacy (β =0.237, P<0.001) was the strongest predictor of self-care behaviors, followed by perceived barriers (β =-0.195, P<0.001) and perceived social support (β =0.13, P<0.001). Perceived benefits did not significantly predict self-care behaviors.ConclusionAccording to the results of this study, it is suggested that designing and implementing training programs to improve self-efficacy and perceived social support of cardiovascular patients and also decreasing barriers to self-care may improve self-care behaviors among patients undergoing angioplasty.
