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

Abstract

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.
