Summary

A retrospective study to assess the utility of hematological marker (monocyte to large platelet ratio) to diagnose patients with pulmonary embolism

Detailed description

The investigators conducted a retrospective review of emergency department records of patients who presented with signs and symptoms suggestive of pulmonary embolism (PE) and underwent CT pulmonary angiography (CTPA) for diagnosis. Hematological laboratory findings obtained prior to any treatment were collected and compared between two groups based on CTPA results: those with confirmed PE (CT positive) and those without PE (CT negative).

Conditions

• Pulmonary Embolism (Diagnosis)
• Diagnosis

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Monocyte to Large Platelet Ratio (MLPR)	Admission laboratory values were used to calculate the Monocyte-to-Large Platelet Ratio (MLPR) by dividing the absolute monocyte count by the large platelet count. These values were obtained from blood samples collected before any treatment was administered.
