Diagnosis and prevention of atherosclerotic cerebral infarction

Area of Science:

• Neurology
• Cardiovascular Medicine
• Public Health

Background:

• Atherosclerotic disease is a significant contributor to ischemic stroke, accounting for roughly 25% of cases.
• Embolic events originating from the carotid artery bifurcation or aortic arch are primary causes, though intracranial thrombosis is more prevalent in specific demographics and patients with diabetes.
• Risk factors for atherosclerosis, including hypertension, diabetes, smoking, and hypercholesterolemia, underscore the importance of primary stroke prevention.

Purpose of the Study:

• To highlight the critical role of atherosclerotic disease in ischemic stroke etiology.
• To emphasize the necessity of primary stroke prevention strategies in individuals with atherosclerosis risk factors.
• To underscore the importance of identifying and managing carotid artery stenosis for secondary stroke prevention.

Main Methods:

• Review of existing literature on atherosclerotic stroke causes and risk factors.
• Analysis of diagnostic approaches for carotid artery stenosis, focusing on non-invasive testing.
• Evaluation of preventative strategies for patients with established atherosclerotic disease and transient ischemic symptoms.

Main Results:

• Atherosclerosis is a major cause of ischemic stroke, primarily through embolic mechanisms.
• Non-invasive testing for carotid artery stenosis enables identification and management, crucial for preventing recurrent strokes.
• Proactive management of risk factors and early detection of carotid artery stenosis can significantly reduce stroke incidence.

Conclusions:

• Effective stroke prevention hinges on managing atherosclerosis and its associated risk factors.
• Non-invasive assessment of carotid artery stenosis is vital for secondary stroke prevention in patients with atherosclerotic disease.
• Vigilance for transient ischemic symptoms in patients with carotid artery stenosis is paramount for timely intervention.
