title: Idiosyncratic reaction to intracoronary injection of non-ionic contrast media.
abstract: Four patients who developed coronary artery spasm in response to their first intracoronary injection of a non-ionic contrast agent, either iopamidol or iohexol, are described. It is suggested that this idiosyncratic reaction may be related to the non-ionic character of these contrast media.
