Troponin release after exertional vasovagal syncope

Abstract

Troponin release following exertional vasovagal syncope has not previously been reported. A young man was investigated after being admitted twice with exertional syncope, each time followed by a 10-fold spike in troponin I over 24 h. Treadmill exercise tests reproduced his symptoms and demonstrated a vasovagal mechanism. During recovery, despite lying supine, he remained hypotensive for 5 min, with profound bradycardia and ST segment depression. We suspected that intense cardiovagal neural activity may have caused the troponin leak.
