Treatment of Atherosclerosis
Atherosclerosis, a condition characterized by the buildup of plaques in arterial walls, poses significant risks to cardiovascular and cerebrovascular health. Effective treatment aims to halt disease progression, prevent complications, and reduce recurrence after interventions.

Key Points
- Medical treatment focuses on preventing thrombosis and managing risk factors.
- Surgical interventions, such as carotid endarterectomy (CEA), are effective for high-grade stenosis.
- Long-term management includes lifestyle changes and adherence to prescribed therapies.
Medical Treatment
The primary goal of medical treatment is to halt the progression of atherosclerosis, prevent cerebral ischemia, and reduce the risk of recurrent lesions.
Antiplatelet Therapy
- Purpose:
- Prevent thrombosis on atherosclerotic plaques and reduce the risk of cerebral ischemia.
- Common agents:
- Aspirin: Widely used; effective at doses of 30–1300 mg/day. Recommended dose: 50–325 mg/day.
- Ticlid (ticlopidine): More effective than aspirin but associated with greater adverse reactions.
- Considerations:
- For patients unresponsive to aspirin, alternative agents or oral anticoagulants may be used.
Anticoagulant Therapy
- Indications:
- Used when antiplatelet drugs are ineffective or not tolerated.
- Common agents:
- Warfarin: The most commonly used oral anticoagulant.
- Monitoring:
- Regular blood tests to ensure therapeutic levels and minimize bleeding risks.
Surgical Treatment
Carotid Endarterectomy (CEA)
- Indications:
- Symptomatic carotid atherosclerosis with high-grade stenosis (70%–99%).
- Procedure:
- Surgical removal of plaque from the carotid artery to restore blood flow.
- Reduces the incidence of cerebrovascular disease and associated medical costs.
- History and prevalence:
- Introduced in the 1950s; refined over decades.
- Approximately 100,000 procedures performed annually in the United States.
Challenges and Future Directions
- Challenges:
- Identifying patients who will benefit most from specific treatments.
- Managing side effects of long-term antiplatelet and anticoagulant therapies.
- Future directions:
- Advances in minimally invasive surgical techniques.
- Development of novel antiplatelet and anticoagulant agents with fewer side effects.
Patient and Public Education
- Raise awareness of the importance of early detection and management of atherosclerosis.
- Promote adherence to prescribed therapies and regular follow-ups.
- Encourage lifestyle changes, including a heart-healthy diet, regular exercise, and smoking cessation.
Atherosclerosis treatment continues to evolve, offering effective medical and surgical options to improve outcomes and quality of life for patients worldwide.
