Risk Factors Favoring Plaque Erosion

Area of Science:

• Cardiovascular Pathology
• Thrombosis Research

Background:

• Plaque erosion is the second leading cause of coronary thrombosis, a critical factor in acute coronary syndromes and sudden cardiac death.
• While plaque rupture mechanisms are known, those for plaque erosion are less understood, necessitating further research.

Purpose of the Study:

• To review current literature on the characteristics and risk factors associated with plaque erosion.
• To summarize recent advances in understanding the pathophysiology of plaque erosion.

Main Methods:

• Literature review of studies on plaque erosion characteristics and risk factors.
• Synthesis of current knowledge on pathogenic and molecular mechanisms.

Main Results:

• Plaque erosion features a defective endothelial layer with an intact fibrous cap, leading to thrombus formation.
• It predominantly affects younger women (<50 years) and smokers, with underlying lesions like pathologic intimal thickening or fibroatheroma.
• Identified risk factors include gender, age, smoking, and disturbed shear flow, with emerging insights into endothelial shear stress and inflammatory pathways.

Conclusions:

• Understanding plaque erosion's risk factors is crucial for developing targeted diagnostics and therapeutics.
• Preventing arterial thrombosis progression can be improved by addressing the specific mechanisms of plaque erosion.
