Venous Thrombosis I: Introduction01:30

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...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

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 I: Introduction01:19

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

Summary

Stent thrombosis, a serious complication of coronary stenting, occurred in 0.85% of patients. Lower socioeconomic status and acute myocardial infarction were significant predictors of this event.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Public Health

Background:

  • Stent thrombosis is a rare but serious complication following coronary stent implantation.
  • Assessing incidence and predictors in a real-world setting is crucial for patient outcomes.

Purpose of the Study:

  • To investigate the association between socioeconomic status and the occurrence of stent thrombosis.
  • To identify clinical predictors of stent thrombosis in a real-world patient cohort.

Main Methods:

  • A retrospective analysis of patients undergoing coronary stent implantation between 2004-2006.
  • Cases of definite stent thrombosis were matched with controls; socioeconomic status was assessed using standardized databases.
  • Demographic and clinical parameters were compared between groups.

Main Results:

  • The incidence of definite stent thrombosis was 0.85% (29 cases) among 3401 patients.
  • Patients with stent thrombosis had higher rates of acute myocardial infarction at initial procedure (76% vs. 32%) and were more likely to be smokers (60% vs. 28%).
  • Significantly lower socioeconomic status (3.4 vs. 5.4 on a 1-10 scale) was observed in the stent thrombosis group (P < 0.01).

Conclusions:

  • The incidence of stent thrombosis in this population is at least 0.85%.
  • Lower socioeconomic status and specific clinical factors are associated with an increased risk of stent thrombosis.
  • Findings support enhanced follow-up for high-risk patients and inform healthcare policies.
