Coronary atherosclerosis, a chronic inflammatory process, causes heart disease. Platelets play a key role in thrombus formation and plaque healing, necessitating new antithrombotic agents.
Area of Science:
- Cardiovascular Medicine
- Inflammation Biology
- Hematology
Background:
- Coronary atherosclerosis is a leading cause of heart disease, driven by chronic inflammation, not just aging.
- Atherosclerotic plaque phenotype (rupture vs. erosion) dictates lesion characteristics and clinical event risk.
- Platelet activation and thrombus formation differ based on plaque phenotype.
Approach:
- This review examines plaque phenotype in relation to thrombus composition.
- It overviews mediators of plaque-induced platelet activation: hemodynamics, matrix components, and soluble factors.
- The review summarizes recent findings on plaque healing and platelet involvement.
Key Points:
- Plaque rupture and erosion initiate platelet activation differently.
- Mediators like hemodynamics, matrix components, and soluble factors influence platelet activation.
- Platelets may play a role in plaque healing after disruption.
Conclusions:
- Understanding plaque phenotype is crucial for predicting clinical events.
- Platelet function in thrombus formation and plaque healing requires further investigation.
- There is a clinical need for improved antithrombotic therapies.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
