The utility of the systemic immune inflammation and systemic inflammation response indices in suspected intermediate-risk pulmonary embolism.

Aim: To evaluate the utility of the systemic immune inflammation index (SII) and systemic inflammation response index (SIRI) in diagnosing pulmonary embolism (PE) in emergency medicine.

Methods: We retrospectively reviewed the data of patients who presented to the emergency department and underwent contrast-enhanced computed tomography pulmonary angiography for suspected PE between January 1 and December 31, 2021. In 81/168 patients, the diagnosis of PE was confirmed and in 87/168 it was rejected.
