title: [Case of electrocardiogram showing ST depression after nonionic contrast media (iopromide) administration].
abstract: A 77-year-old man with coronary artery stenosis underwent the left limb artery bypass grafting. When the contrast media was administered on intraoperative limb reperfusion after revascularization, electrocardiogram showed ST depression without skin symptoms and blood pressure decline. The change was not in the right coronary artery area (99% stenosis), but in the left coronary artery area (50% stenosis). The nonionic contrast media may elicit coronary artery vasoconstriction, although there are few side effects including anaphylactic in comparison with the ionic contrast media. In administration of the nonionic contrast media to the patient with coronary artery stenosis (50% or more), it is important to examine electrocardiogram, and is advisable to administer coronary artery dilating drug before-hand.
