Insights

Late stent thrombosis (ST) after drug-eluting stent implantation is a rare but serious complication. Research is ongoing to understand its causes and prevent it through optimal antiplatelet therapy and new stent designs.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Biomaterials Science

Background:

  • Drug-eluting stents (DES) are widely used in percutaneous coronary intervention (PCI).
  • Late and very late stent thrombosis (ST) is an uncommon but severe complication following DES implantation.
  • ST can lead to acute myocardial infarction or sudden cardiac death.

Purpose of the Study:

  • To review the current understanding of stent thrombosis risk after DES implantation.
  • To discuss the role of dual antiplatelet therapy (DAPT) in preventing ST.
  • To highlight ongoing research into novel stent technologies and therapeutic strategies.

Main Methods:

  • Literature review of studies on stent thrombosis incidence and predictors.
  • Analysis of the role of dual antiplatelet therapies (DAPT).
  • Discussion of emerging research on platelet reactivity testing, genetic testing, and stent design.

Main Results:

  • Stent thrombosis, though uncommon, carries a high risk of adverse cardiac events.
  • Dual antiplatelet therapy is crucial in mitigating ST risk.
  • Newer stent technologies, including polymer-free and bioabsorbable stents, show promise in reducing ST.

Conclusions:

  • Minimizing stent thrombosis risk remains a critical goal in interventional cardiology.
  • Optimizing antiplatelet therapy duration and modality is essential.
  • Investigating novel stent designs is a key area for future research to improve patient outcomes.

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
Pulmonary Embolism III: Nursing Management01:27

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
