Clinical Scores, Biomarkers, and CT Findings in Acute Pulmonary Embolism

This study is an observational analytical study designed to evaluate and compare clinical scoring systems, laboratory biomarkers, and computed tomography (CT) findings in patients presenting with acute pulmonary embolism (PE) across different hospital departments at Sohag University Hospital.

Acute pulmonary embolism is a potentially life-threatening condition that requires prompt diagnosis and risk stratification. Various clinical scores (such as Wells score and Geneva score), along with laboratory biomarkers (such as D-dimer and others), and imaging modalities (especially CT pulmonary angiography), are commonly used in the diagnostic and assessment process.

The study aims to assess the diagnostic accuracy and clinical usefulness of these parameters, individually and in combination, in patients with confirmed acute pulmonary embolism.

Data will be collected retrospectively and/or prospectively from patient records and clinical assessments. Variables will include demographic data, clinical presentation, risk factors, laboratory investigations, clinical scoring systems, and radiological findings.

The study will compare these parameters across different hospital departments to determine variations in presentation and diagnostic approaches, as well as to evaluate the best predictive indicators for disease severity and outcomes.

The findings of this study may contribute to improving clinical decision-making, optimizing diagnostic strategies, and enhancing early identification of high-risk patients with acute pulmonary embolism.

This is a non-interventional observational study, and no experimental treatment or intervention will be applied. All data will be handled with confidentiality and in accordance with ethical standards and institutional review board (IRB) approval.
