The Role of Oxidative Stress and MicroRNAs in Platelet Activation and the Efficacy of Antiplatelet Therapy in Acute Myocardial Infarction

Acute myocardial infarction (AMI) remains a formidable challenge in cardiovascular medicine, necessitating effective antiplatelet therapy to mitigate adverse outcomes. Recent advances have underscored the pivotal role of oxidative stress and micro ribonucleic acids (miRNAs) in regulating platelet activation and modulating the efficacy of antiplatelet agents. This review comprehensively examines the current understanding of how oxidative stress influences platelet function and the regulatory mechanisms of miRNAs in this context. It discusses the dual role of oxidative stress in promoting and impairing platelet activity and its implications for miRNAs as critical modulators of platelet activation, including their potential utility as biomarkers and therapeutic targets. Furthermore, the interaction between oxidative stress, miRNA expression, and antiplatelet drugs is analyzed to elucidate their combined impact on AMI treatment. These insights provide potential pathways to optimize therapeutic strategies, ultimately improving patient outcomes in AMI management.
