Introduction
Ischemic stroke is a heterogeneous condition with multiple underlying causes, each associated with distinct risk factors, mechanisms, and implications for secondary prevention. Accurate identification of stroke etiology is a cornerstone of effective management, as it directly informs diagnostic pathways, therapeutic decisions, and long-term prevention strategies.
To support healthcare professionals in understanding this complexity, the World Stroke Academy has developed an educational infographic titled “Beyond The Clot: Understanding Ischemic Stroke Etiology.” The infographic offers a clear, visual overview of the main etiological subtypes of ischemic stroke and highlights their relative contribution to global stroke burden.
Key educational themes
- The major etiological classifications of ischemic stroke, including large artery atherosclerosis, cardioembolic stroke, small vessel disease, and less common or undetermined causes
- The underlying pathophysiological mechanisms associated with each stroke subtype
- The clinical relevance of etiological classification for diagnostic work-up and secondary prevention strategies
- The importance of individualized management approaches based on stroke mechanism
By presenting essential concepts in a concise and accessible format, the infographic aims to reinforce foundational knowledge and support a structured approach to stroke classification in clinical practice. This educational resource is designed to complement existing classification systems and guidelines, while encouraging ongoing education in an area that remains critical to improving patient outcomes.
