Insights
A patient experienced a heart attack 41 months after a sirolimus-eluting stent implantation. Coronary angiography confirmed stent thrombosis as the cause.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomedical Engineering
Background:
- Drug-eluting stents (DES) are widely used to treat coronary artery disease.
- Sirolimus-eluting stents (SES) have demonstrated efficacy in reducing restenosis.
- Late stent thrombosis remains a potential complication following DES implantation.
Observation:
- A 67-year-old male presented with symptoms of non-ST-elevation acute myocardial infarction.
- The patient had a history of sirolimus-eluting stent implantation in the left circumflex artery 41 months prior.
- Clinical presentation suggested a cardiac event despite prior successful stenting.
Findings:
- Coronary angiography was performed to investigate the cause of myocardial infarction.
- The investigation revealed definitive evidence of stent thrombosis in the left circumflex artery.
- Thrombosis occurred significantly late after the sirolimus-eluting stent implantation.
Implications:
- This case highlights the possibility of late stent thrombosis even with modern drug-eluting stents.
- Understanding the mechanisms of late stent thrombosis is crucial for optimizing antiplatelet therapy and stent design.
- Further research is warranted to identify risk factors and preventive strategies for late stent thrombosis.
Abstract:
We report the case of a 67-year-old man who presented with a [corrected] non-ST-elevation acute myocardial infarction 41 months after implantation of a sirolimus-eluting stent in his left circumflex coronary artery. Coronary angiography revealed stent thrombosis.

01:30Venous Thrombosis IV: Nursing Management
208
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

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...

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...

01:30Venous Thrombosis I: Introduction
410
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...

1.4K
In High-Performance Liquid Chromatography (HPLC), the elution process is critical to the separation of analytes and the quality of chromatographic results. Elution describes how compounds move through the column and separate based on their interactions with the mobile and stationary phases. This process determines the resolution, peak shape, and retention times in the chromatogram, which are essential for identifying and quantifying components in complex mixtures. Understanding the elution...

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”
