Adherence to antiplatelet treatment with P2Y12 receptor inhibitors. Is there anything we can do to improve it? A systematic review of randomized trials.
Antiplatelet therapy is the cornerstone of treatment for patients with acute coronary syndromes (ACS) and/or undergoing percutaneous coronary interventions. Non-adherence to medication after ACS may lead to increased morbidity, mortality, and costs to the healthcare system due to elevated risk of stent thrombosis, myocardial infarction or death. Medication adherence is an issue of growing concern regarding the improvement of health system performance. Promoting medication adherence offers a rare opportunity to simultaneously improve health outcomes while reducing costs of treatment in patients with coronary artery disease (CAD). The aim of this systematic review was to critically discuss adherence to antiplatelet treatment with P2Y12 receptor inhibitors in CAD patients. After a systematic investigation of the literature in databases including PubMed, CENTRAL and Google Scholar, using appropriate keywords, and considering clinical randomized, prospective observational and retrospective studies, reporting on adherence to treatment with inhibitors of P2Y12 platelet receptors or educational interventions aimed to improve medication adherence in patients with CAD, seven articles were considered eligible for inclusion in this systematic review. Reported adherence to clopidogrel, despite catastrophic consequences of its premature discontinuation, is low. We identified several determinants of low adherence and early discontinuation of clopidogrel. We also present data on the usefulness, utilization and credibility of different methods of medication adherence assessment, and suggest and critically discuss available interventions aimed at improvement of adherence to clopidogrel, still showing the need for innovative approaches to achieve enhanced medication adherence and improve health outcomes after acute myocardial infarction.
