Classifying ischemic stroke is an important step in understanding its underlying mechanism and determining the most appropriate therapy. Ischemic stroke occurs when blood flow to the brain is blocked, causing brain tissue damage due to a lack of oxygen and nutrients.
The causes vary, from blockages in large blood vessels, emboli originating from the heart, to occlusion of small blood vessels. By identifying the type and cause of the stroke, medical professionals can design appropriate treatments and reduce the risk of recurrence.
In general, ischemic strokes are categorized into several major types:
Each type has distinct mechanisms, risk factors, and clinical characteristics.
This type of stroke occurs due to the formation of a thrombus (blood clot) on an atherosclerotic plaque in large arteries, such as the carotid or cerebral arteries. When the plaque becomes damaged or ruptures, it triggers platelet activation and blood clotting, resulting in a blockage that restricts blood flow to the brain.
Atherothrombotic stroke usually develops gradually, starting with mild symptoms that worsen over hours or days.
Main risk factors include:
Atherosclerosis, the underlying process, involves the buildup of cholesterol plaques on the arterial walls, gradually narrowing the artery lumen and increasing stroke risk.
Cardioembolic stroke is caused by a blood clot or embolic material that forms in the heart and travels to the brain. This can result from:
Unlike atherothrombotic stroke, this type typically presents suddenly with severe symptoms from the onset.
There’s also a higher risk of recurrence, making tight control of heart disease crucial for prevention.
Lacunar stroke occurs due to occlusion of small blood vessels in the brain, commonly associated with chronic hypertension or diabetes-related small vessel disease.
Although the lesions are small, they can cause focal neurological symptoms such as:
Despite their small size, repeated lacunar strokes can significantly impair brain function over time.
In some cases, the cause of an ischemic stroke cannot be identified, even after thorough examination. This is referred to as cryptogenic stroke.
Possible causes may involve hidden risk factors or complex mechanisms that have not yet been detected.
Management generally focuses on secondary prevention, such as:
Partner hospitals of AIA, such as National Hospital Surabaya, use ischemic stroke classification based on the underlying cause to determine optimal diagnosis and treatment. The three main categories include:
This approach helps medical professionals tailor treatment strategies, including:
Use of antiplatelet drugs
Anticoagulants
Surgical interventions or endovascular procedures
In addition, AIA partner hospitals emphasize risk factor control, such as blood pressure and glucose level management, to prevent stroke recurrence. Advanced diagnostic tools ensure accurate identification of the stroke’s cause.
Understanding the classification of ischemic stroke is key to determining the right diagnostic and therapeutic path. Atherothrombotic, cardioembolic, lacunar, and cryptogenic strokes each have unique characteristics and require specific treatment approaches.
AIA partner hospitals adopt this classification system to improve treatment outcomes while prioritizing prevention through risk factor management.
