Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

68
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...

Acute Coronary Syndrome III: Diagnostic Studies

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

71
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

Elevated D-dimer levels are strong predictors of 30-day mortality in patients with suspected or confirmed COVID-19. This finding holds true for both infected and non-infected individuals, highlighting D-dimer

Area of Science:

  • Clinical Medicine
  • Infectious Diseases
  • Emergency Medicine

Background:

  • Elevated D-dimer levels are recognized in COVID-19 patients and possess prognostic value.
  • Previous studies lacked comparison with an appropriate control group for D-dimer's prognostic significance.

Purpose of the Study:

  • To investigate the prognostic value of D-dimer levels in emergency patients with suspected or confirmed COVID-19.
  • To compare the association of D-dimer levels with 30-day mortality in COVID-19 positive versus negative patients.

Main Methods:

  • An observational cohort study was conducted on 953 emergency patients.
  • Logistic regression analysis was employed to assess the association of D-dimer levels, COVID-19 status, age, and gender with 30-day mortality.

Main Results:

  • Overall, 56% of patients presented with elevated D-dimer levels (≥0.5mg/l).
  • Age (OR 1.07), D-dimer levels ≥0.5mg/l (OR 2.44), and COVID-19 positivity (OR 2.79) were significantly associated with 30-day mortality.
  • The 30-day mortality rate was 7.4% in confirmed COVID-19 patients and 3.5% in those without SARS-CoV-2 infection.

Conclusions:

  • D-dimer levels are effective prognostic indicators for 30-day mortality in emergency patients.
  • The prognostic value of D-dimer extends to both COVID-19 positive and negative patient cohorts.
