Antiplatelet Therapy and Its Importance After Vascular Stenting
Antiplatelet therapy is a critical component of care following vascular stent placement. Because stents are foreign objects within blood vessels, they increase the risk of platelet activation and clot formation. Without proper medication, these clots can obstruct blood flow and lead to life-threatening complications.
Platelets naturally respond to vessel injury by forming clots. While this process is essential for healing, it can become dangerous in the presence of a stent. Antiplatelet medications work by reducing platelet aggregation, allowing blood to flow smoothly through the treated vessel.
Most patients are prescribed dual antiplatelet therapy initially, often consisting of aspirin combined with another antiplatelet agent. The duration of therapy depends on factors such as stent type, location, and individual bleeding risk. Drug-eluting stents generally require longer treatment than bare-metal stents.
Strict adherence to antiplatelet therapy is essential. Premature discontinuation significantly increases the risk of stent thrombosis, which can cause heart attacks, strokes, or limb-threatening ischemia. Patients should never stop these medications without consulting their healthcare provider.
Healthcare providers carefully balance clot prevention with bleeding risk. Regular follow-up helps adjust therapy as needed. Patients are advised to inform all healthcare professionals, including dentists and surgeons, about their stent and medication regimen.
Antiplatelet therapy has greatly improved the safety and success of vascular stenting. When combined with proper lifestyle changes and medical supervision, it helps ensure long-term vessel patency and patient well-being.
