Background: Syncope is a Transient Loss of Consciousness (TLOC) due to cerebral hypoperfusion, it shares many clinical features with many disorders and therefore it is encountered in many differential diagnoses. Our patient is a 33 years old man, former smoker, with a history of multiple episodes of TLOC and elevated high-sensitive Troponin I (hs-TnI) values. Case Report: The patient reached medical assessment after the first episode of TLOC, in 2013, when he was diagnosed with clinically suspected myocarditis due to persistently elevated hs-TnI and elevated C-Reactive Protein (CRP), and based on Cardiac Magnetic Resonance (CMR) findings. The second episode was in 2017 when clinical and additional examinations concluded for syncope. The third episode was in August 2020. All these episodes were associated with persistently elevated plasma hs-TnI concentrations. Conclusion: in this case neuromediated syncope was responsible for the recurrent TLOCs, while persistently elevated hs-TnI levels were associated with macro-troponin complexes formation, with no evidence of pathological implication.
