Supraventricular tachycardia promotes release of troponin I in patients with normal coronary arteries

Int J Cardiol. 2005 Jul 20;102(3):521-2. doi: 10.1016/j.ijcard.2004.05.076.


Background: Troponin I and T are sensitive markers of myocardial injury. The presence of elevated troponin often prompts further investigation with coronary angiography.

Methods: We present a series of patients presenting to our unit with raised troponin I and supraventricular tachycardia (SVT) that prompted coronary angiography.

Results: All patients had normal epicardial vessels at angiogram, no evidence of muscle bridging or pulmonary embolism.

Conclusion: The presence of tachycardia sufficient to warrant hospital admission can raise troponin, and this should be viewed in context when a decision on angiography is to be taken.
