Abstract

Myocardial perfusion scintigraphy is a popular minimally invasive method for evaluating chronic coronary disease (CCD). We performed myocardial scintigraphy to assess CCD in a 74-year-old man with a history of allergy to contrast media. The patient developed anaphylactic shock immediately after the administration of the technetium (^99mTc)-tetrofosmin preparation. This is the first report of anaphylactic shock due to ^99mTc-tetrofosmin administration during myocardial perfusion scintigraphy.

Keywords: allergic reaction; anaphylactic shock; myocardial scintigraphy; stable ischemic heart disease; technetium tc-99m.
