Platelet function testing guides antiplatelet therapy in high-risk coronary artery disease. Current evidence does not support personalized therapy based on these tests for reducing ischemic events.
Area of Science:
- Cardiology
- Hematology
- Pharmacology
Background:
- Platelets are crucial in thrombosis and ischemic events in high-risk coronary artery disease.
- Dual antiplatelet therapy (aspirin and P2Y12 inhibitor) is standard care.
- Point-of-care platelet function tests (PFTs) are increasingly used.
Purpose of the Study:
- To evaluate the clinical utility of PFTs in guiding antiplatelet therapy.
- To assess the relationship between PFT results and clinical outcomes.
- To determine if personalized antiplatelet therapy based on PFTs reduces ischemic events.
Main Methods:
- Review of observational studies and prospective randomized trials on PFTs.
- Analysis of the association between PFT results and clinical events (ischemia, bleeding).
- Exploration of the therapeutic window concept for P2Y12 receptor reactivity.
Main Results:
- Observational studies show a link between PFT results and clinical events.
- Prospective trials have not demonstrated that PFT-guided personalized therapy reduces ischemic events.
- Limitations exist in current trial designs and the proposed therapeutic window concept.
Conclusions:
- Strong prospective evidence supporting PFT-guided personalized antiplatelet therapy is lacking.
- Clinical decisions rely on observational data and the established role of platelet physiology.
- Further research is needed to clarify the role of PFTs in managing antiplatelet therapy.

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...

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
