Abstract
BACKGROUND: Stroke remains one of the leading causes of mortality and disability worldwide. Despite the proven effectiveness of antiplatelet therapy as secondary prevention of ischemic stroke, patients’ adherence to long-term medication regimens remains low. This issue is particularly pronounced in patients with recurrent non-cardioembolic stroke. Investigating the factors that influence adherence to therapeutic recommendations is essential for developing individualized follow-up strategies and enhancing treatment effectiveness in outpatient practice.
AIM: This study aimed to evaluate the association between adherence to antiplatelet therapy and the development of recurrent non-cardioembolic ischemic stroke, and to analyze factors associated with high and low adherence.
METHODS: A total of 1971 patients with ischemic stroke and transient ischemic attack were examined. The study included 831 patients with recurrent non-cardioembolic stroke. The MoCA, HADS, and ESRS scales were used. Analyses were performed using logistic regression.
RESULTS: Regular medication intake was reported by 48.9% of patients; 16.6% demonstrated inconsistent adherence, whereas 34.5% discontinued their therapy. High adherence was associated with higher educational level, urban residence, family support, better cognitive function, and greater patient awareness (according to the survey) of the recurrence risk. Depression showed an association with low adherence in univariate analysis but did not remain significant in logistic regression. More than 60% of patients who did not take their medications experienced recurrent stroke within the first three months, whereas highly adherent patients remained recurrence-free for two years or longer.
CONCLUSION: Adherence to antiplatelet therapy is shaped by multiple factors. These findings underscore the need for individualized strategies for patient monitoring and support in the outpatient setting.
