Insights

Clopidogrel resistance caused stent thrombosis in a patient despite dual antiplatelet therapy. Switching to ticagrelor resolved the issue, suggesting tailored antiplatelet therapy may be beneficial.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Percutaneous coronary intervention (PCI) is a common procedure for coronary artery disease.
  • Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is standard post-PCI to prevent stent thrombosis.

Observation:

  • A 65-year-old male patient experienced 3-vessel stent thrombosis despite receiving aspirin and clopidogrel.
  • Platelet function testing identified resistance to clopidogrel.

Findings:

  • The patient's clopidogrel resistance resolved upon switching antiplatelet medication to ticagrelor.
  • This switch successfully managed the stent thrombosis.

Implications:

  • While routine platelet testing post-stenting is not standard, it can be valuable in refractory cases.
  • Identifying specific antiplatelet drug resistance can guide personalized therapy to prevent stent thrombosis.
  • Ticagrelor may be a viable alternative for patients exhibiting clopidogrel resistance.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...
