Key result
Serum cardiac troponin I elevation was observed in 31.9% of patients with supraventricular tachycardia without coronary artery disease, and was significantly associated with interventricular septal thickness (p<0.0001) and hypertension (p=0.0460).
Observational (n=69)
No
Cardiac troponin I elevation occurs in nearly a third of patients with supraventricular tachycardia without coronary artery disease, and is associated with structural heart changes and hypertension rather than tachycardia characteristics.
Troponin elevation in SVT without CAD may reflect hypertrophy or hypertension; leaves open clinical implications pending prospective data.

Kim et al. (2006) conducted an observational in Supraventricular tachycardia without evidence of coronary artery disease (n=69). Supraventricular tachycardia was evaluated on Incidence of serum cardiac troponin I (cTnI) elevation. Serum cardiac troponin I elevation was observed in 31.9% of patients with supraventricular tachycardia without coronary artery disease, and was significantly associated with interventricular septal thickness (p<0.0001) and hypertension (p=0.0460).
