Key result
A 77-year-old patient with supraventricular tachyarrhythmia presented with highly elevated cardiac troponin despite normal coronary arteries on angiography and intravascular ultrasound.
Why the study?
Elevated cardiac troponin is a gold standard biomarker for acute coronary syndrome, but it can also occur in other clinical situations such as supraventricular tachyarrhythmia.
Case Report (n=1)
Highly elevated cardiac troponin can occur in supraventricular tachyarrhythmia without underlying coronary artery disease.
Troponin elevation in SVT may not indicate ACS; leaves open need for prospective validation of arrhythmia-specific thresholds.
Although elevated cardiac troponin is considered to be the gold standard biomarker for the identification of acute coronary syndrome, it may also occur in other clinical situations as supraventricular tachyarrhythmia (SVT) and acute coronary syndrome. We reported the case of a 77-year-old patient with a highly elevated cTn after the onset of SVT. Normal coronary arteries were detected through coronary angiography and intravenous ultrasound. It seems that the association of the cardiac troponin elevation in SVT patients with future cardiovascular events is very low. Meanwhile, more attention should be paid to those patients with high cardiovascular risk factors.

Chen et al. (2021) conducted a case report in Supraventricular tachyarrhythmia with elevated cardiac troponin (n=1). Supraventricular tachyarrhythmia was evaluated. A 77-year-old patient with supraventricular tachyarrhythmia presented with highly elevated cardiac troponin despite normal coronary arteries on angiography and intravascular ultrasound.
