Abstract

Introduction: Treatment adherence refers to the degree to which an individual’s behavior complies with health or treatment recommendations. Objective: This study aims to determine treatment adherence and the related factors among patients with myocardial infarction (MI) admitted to selected hospitals in Hilla, Iraq. Materials and Methods: In this cross-sectional study, 264 patients over 18 years of age diagnosed with MI for at least six months from three hospitals in Hilla, Iraq, were selected by a convenience sampling method. A demographic form and the coronary artery disease treatment adherence scale (CADTAS) were used to collect data. Pearson correlation test, Independent t-test, analysis of variance, multivariable general linear model (GLM) and Wilk’s lambda statistic was used for data analysis. Results: Most of the participants were male (72.7%), married (72.3%), worker (44.3%) with a middle school education (28%) and a mean age of 60.87±8.25. The mean total CADTAS score was 92.28±8.01( From 35 to 175 possible scores). The CADTAS score had significant and negative relationship with age (r=-0.225, P=0.001) and age at the onset of diagnosis (r=-0.239, P=0.001). The results of the GLM showed the significant and negative association of the history of heart attack (B=-2.645; 95% CI, -5.106, -0.184, P=0.035) and the history of underlying diseases (B=-2.828, 95% CI, -5.463, -0.193, P=0.036) with the CADTAS score. Also, the medication use duration was positively and significantly associated with the CADTAS score (B=1.145; 95%CI, 0.069, 2.222, P=0.037). Also, Wilks’ Lambda values showed a significant difference in the CADTAS score in terms of gender (Wilks’ Lambda =0.933, P=0.002), occupation (Wilks’ Lambda =0.845, P=0.001), history of heart attack (Wilks’ Lambda =0.950, P=0.013), history of underlying diseases (Wilks’ Lambda =0.953, P=0.018), and medication use duration (Wilks’ Lambda =0.938, P=0.003) Conclusion: The results of this study showed that the mean score obtained by the study samples was higher than the mean score of the tool used to determine the level of adherence. Given the MI patients’ treatment adherence scores, more studies are needed to determine the reasons for non-adherence to treatment in Iraqi patients with MI. Planning education for these patients and their families can be helpful to increase their treatment adherence. © 2025 Elsevier B.V., All rights reserved.
