Adenosine-induced coronary artery spasm: a case report.
OBJECTIVE
To describe an uncommon complication of intravenous adenosine administration.


METHODS
A 41-year-old female patient presented with palpitations due to supraventricular tachycardia. The patient was treated with intravenous adenosine with resolution of the tachycardia. Subsequently, the patient developed chest pain and ST segment elevation in the inferior leads that resolved with sublingual nitroglycerin.


CONCLUSIONS
This report showed a case of coronary spasm secondary to the administration of adenosine. We therefore recommend that discretion be exercised when giving adenosine, especially to patients with an underlying tendency for vasospastic reactions.
