Summary
Cocaine use complicates medical treatment, leading to poor adherence. This case highlights subacute stent thrombosis in a cocaine user, suggesting balloon angioplasty may be preferred for interventions.
Area of Science:
- Cardiology
- Toxicology
- Emergency Medicine
Background:
- Cocaine is frequently abused by emergency room patients.
- Poor adherence to medical advice and medications is common in cocaine users.
- Subacute stent thrombosis is a serious complication following coronary stent implantation.
Observation:
- A 41-year-old cocaine user presented with subacute stent thrombosis three days after bare metal stent implantation.
- The patient was compliant with dual antiplatelet therapy prior to the event.
- Treatment involved manual/mechanical thrombectomy and percutaneous transluminal coronary angioplasty.
Findings:
- Cocaine use is linked to an increased risk of thrombosis in both native vessels and coronary stents.
- Patient compliance issues in cocaine users can exacerbate cardiovascular risks.
- This case illustrates a severe thrombotic event despite adherence to antiplatelet therapy.
Implications:
- Balloon angioplasty alone may be the preferred intervention for coronary artery disease in cocaine users requiring procedures.
- Further research is needed to understand cocaine's specific mechanisms in inducing stent thrombosis.
- Clinical vigilance for thrombosis is crucial in emergency room patients with a history of cocaine abuse.

2.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
