Abstract
Syncope is generally considered to occur in patients with pulmonary embolism if they have a sudden obstruction of the most proximal pulmonary arteries that lead to a transient depression in cardiac output. The prognostic role of pulmonary embolism (PE) in patients with syncope is not well investigated. In this retrospective study, 181 normotensive patients with acute PE diagnosed objectively. The patients were classified as 2014 by the European Society of Cardiology guidelines. All patients calculated sPESI score. Patients admitted with hypotension and shock were excluded from the study. The mean age was 67.8 ± 15 years and 39% of them were male. Syncope was identified in 12 (6.7%) patients. In intermediate high-risk PE groups higher is syncope than low risk patients (18.4% vs 3.2%) (p =. 003). The syncope frequency was higher in patients with thrombus in the main pulmonary artery without it (13% vs. 2.6%, p=0.008). Patients with high-risk sPESI had a higher incidence of syncope (9.7% vs 0%, respectively, p =. 035) than those with low-risk sPESI. In addition, thrombolytic therapy was used more in patients with syncope (42% vs 7%, respectively, p <. 001). Conclusion;Syncope can be used in future risk assessment of pulmonary embolism.
