Platelet function inhibitors like aspirin and clopidogrel are crucial for preventing atherothrombotic events. Discontinuing these medications before surgery requires careful balancing of bleeding versus ischemic risks, especially post-stent implantation.
Area of Science:
- Cardiovascular Medicine
- Pharmacology
- Hematology
Context:
- Acetylsalicylic acid (ASA) and clopidogrel are widely prescribed platelet function inhibitors (PFIs).
- These agents are integral to managing various atherothrombotic diseases through mono- or dual antiplatelet therapy.
- Platelet inhibition persists for the entire platelet lifespan (10 days).
Purpose:
- To evaluate the critical balance between bleeding risks and ischemic complications when managing antiplatelet therapy around surgical procedures.
- To address the specific challenges posed by continued antiplatelet therapy after stent implantation, considering the risk of stent thrombosis.
Summary:
- Surgical procedures with low bleeding risks can often proceed with uninterrupted antiplatelet therapy.
- Higher bleeding risk procedures necessitate a careful consideration of partial or complete discontinuation of antiplatelet therapy.
- The decision-making process must weigh the potential for bleeding against the risk of ischemic events, particularly stent thrombosis.
Impact:
- Provides guidance for clinicians on managing antiplatelet therapy in patients undergoing surgery.
- Aims to optimize patient outcomes by minimizing both bleeding complications and thrombotic events.
- Highlights the importance of individualized risk assessment in perioperative antiplatelet management.

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...
