Eighty-four university cardiovascular laboratories responded to a questionnaire concerning premedication practice and observation of noncatheter-induced coronary artery spasm during routine coronary angiography. Half of the laboratories stated that they had not observed the phenomenon. The data suggest that premedication practice may account in part for the relative rarity of this phenomenon.
Kenneth R. Bennett (1976) studied this question.
