Myocardial infarction secondary to contrast agent. Contrast effect or type II Kounis syndrome?

The diagnostic administration of contrast agents has been increased recently in various fields, including coronary angiography, but reports of coronary artery spasm caused by contrast agents are rare. However, myocardial infarction following administration of nonionic contrast agents has not been reported, as far as we are aware. Herein, we described a case of acute anterior myocardial infarction induced by the contrast agent iopromide (Ultravist). We also discussed the possible reasons for this situation.
