Ischemic stroke and intervention strategies based on the timeline of stroke progression: Review and prospects

Abstract

Ischemic stroke (IS), a leading cause of morbidity and mortality worldwide, primarily results from blood clot formation in cerebral vessels, leading to vessel occlusion, reduced cerebral blood flow, and subsequent tissue ischemia. While thrombolytic therapies and mechanical thrombectomy remain cornerstone treatments for restoring blood flow, their clinical efficacy is significantly limited by the narrow therapeutic window, which underscores the critical need for novel, safe, and effective therapeutic strategies. In this review, we present an intensive analysis of four pathophysiological stages of IS progression and their intervention targets, and evaluate both established and emerging therapeutic strategies with the molecular mechanisms underpinning these methods, aiming to enhance the understanding of IS intervention. Additionally, we discuss current challenges in IS therapy, emphasizing the importance of timely, stage-specific approaches to optimize therapeutic outcomes. Finally, we highlight some promising research directions and innovations to advance IS field.
