Diagnostic value of high-sensitivity troponin I to predict cardiac causes after syncope/near syncope in emergency department
Copyright © 2020 Elsevier Masson SAS. All rights reserved..
AIMS: The objective of this study is to evaluate the diagnostic accuracy of high-sensitivity (hs) troponin I to predict cardiac origin after syncope. The secondary objective is to determine the causes of elevated troponin.
PROCEDURE: Were included hospitalized patients with syncope/near syncope diagnosed in ED. The diagnostic accuracy to predict cardiac origin was evaluated and compared to the "high risk" group, defined by the 2018 European Society of Cardiology guidelines.
RESULTS: A total of 163 patients were enrolled, 26% had a cardiac origin. Positive troponin I hs predict a cardiac origin with a sensitivity of 31%, a specificity of 80%, positive predictive value of 35% and negative value of 77%. These diagnostic performances are not discriminating and lower than the ESC classification. A positive troponine I hs level is associated with 5 times more cardiac failure during the hospitalization.
CONCLUSION: A positive troponin I hs level after syncope/near syncope is not predictive of cardiac origin. It appears to be an early marker of ventricular remodeling in heart failure.
