Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

114
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

113
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

123
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 IV: Nursing Management

95
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 I: Introduction

121
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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Summary

Arterial thrombotic events occurred in 5.6% of hospitalized COVID-19 patients, increasing mortality risk. Elevated D-dimer levels over 1250 ng/mL identified high-risk individuals for these dangerous events.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Vascular Medicine

Background:

  • Coronavirus disease 2019 (COVID-19) is associated with a hypercoagulable state.
  • Arterial thrombotic events (ATEs) are a serious complication of COVID-19 infection.
  • Understanding risk factors for ATEs in COVID-19 patients is crucial for clinical management.

Purpose of the Study:

  • To evaluate the clinical course of arterial thrombotic events in adult inpatients with COVID-19.
  • To identify risk factors associated with the occurrence of ATEs in COVID-19 patients.
  • To assess the impact of ATEs on mortality in hospitalized COVID-19 patients.

Main Methods:

  • Retrospective analysis of consecutive adult COVID-19 patients admitted to a French referral center.
  • Data collection on demographic, clinical, laboratory, and treatment variables.
  • Analysis of arterial thrombotic events occurring from admission through discharge.

Main Results:

  • Among 531 COVID-19 patients, 5.6% experienced ATEs.
  • ATEs occurred at a median of 11 days post-symptom onset and were associated with traditional cardiovascular risk factors.
  • Patients with ATEs had a 3-fold increased risk of in-hospital death (HR 2.96).
  • D-dimer levels >1250 ng/mL significantly increased the risk of ATEs (SHR 7.68).

Conclusions:

  • Hospitalized COVID-19 patients experiencing ATEs have a dramatically high in-hospital mortality rate.
  • Elevated D-dimer levels (>1250 ng/mL) at admission may identify COVID-19 patients at increased risk for ATEs.
  • Early identification and management of ATE risk factors are essential in COVID-19 care.
