RESUMEN
BACKGROUND: Effective medication adherence is vital for managing acute myocardial infarction (AMI) and enhancing patient well-being. This study aimed to evaluate medication adherence levels and associated factors among AMI patients using standardized assessment tools. METHODS: Employing a cross-sectional descriptive design, the study involved 210 patients diagnosed with acute myocardial infarction. Participants completed the General Medication Adherence Scale (GMAS), Hospital Anxiety and Depression Scale (HADS), and provided socio-demographic details. RESULTS: The study revealed partial adherence to medications among AMI patients, with mean scores of 24.89 (± 3.64) out of 33. Notably, good adherence was observed in non-adherence due to patient behavior (mean ± SD = 11.8 ± 2.3 out of 15) and additional disease burden (mean ± SD = 8.65 ± 2.21 out of 12), while partial adherence was noted in non-adherence due to financial constraints (mean ± SD = 4.44 ± 1.34 out of 6). Patients reported mild anxiety (mean ± SD = 8.38 ± 2.81) and no depressive symptoms (mean ± SD = 7.43 ± 2.42). Multiple linear regression analysis indicated that employed status, younger age, shorter duration of MI, lower anxiety, and depression levels were associated with higher medication adherence. However, factors such as monthly income, gender, educational level, and marital status did not predict medication adherence. CONCLUSION: The study highlights the significance of addressing anxiety and depression levels and considering socio-demographic factors when designing interventions to enhance medication adherence among AMI patients. Further research is needed to explore additional determinants of medication adherence and develop tailored interventions to improve patient outcomes post-AMI.
