Diagnostic Value of High-Sensitivity Cardiac Troponin-I in Patients After Out-of-Hospital Cardiac Arrest
Copyright © 2023 Elsevier Inc. All rights reserved..
Knowing the etiology of cardiac arrest (CA) is important for treatment decisions. Results of previous studies on the diagnostic role of cardiac troponin in patients resuscitated from CA are controversial, few studies were done during the era of high-sensitivity cardiac troponin-I (hs-cTnI), and kinetics of hs-cTnI was not thoroughly investigated. We aimed to explore the diagnostic value of hs-cTnI in patients resuscitated from out-of-hospital CA (OHCA). This retrospective study included 201 consecutive patients after OHCA admitted to the intensive cardiac care unit at Rambam Health Care Campus from 2016 to 2021. Patients were divided into 2 groups according to etiology of CA: group 1-patients with definite acute myocardial infarction (AMI), group 2-patients in whom AMI was excluded. Values of hs-cTnI on admission, peak hs-cTnI, and hs-cTnI upslope were compared between patients with AMI and non-AMI. Peak hs-cTnI and hs-cTnI upslope differed significantly between patients with non-AMI versus AMI CA (median 1,424 vs 32,558 ng/L, p <0.0001 and median 109 vs 2,322 ng/L/h, p <0.0001, respectively). Moreover, peak hs-cTnI and hs-cTnI upslope were found to have good discrimination performance between patients with non-AMI and AMI, with area under the curve receiver operating characteristics (ROC) curves of 0.83 and 0.80, respectively. In conclusion, in patients resuscitated from OHCA values of peak hs-cTnI and hs-cTnI upslope could be helpful in the diagnosis of etiology of CA as adjunct to other diagnostic methods.
