“…There have been several reports of myocardial ischaemia due to the use of ergotamine, for indications other than migraine, in patients with known heart disease (Labbe et al, 1929a;Lichtman, 1936;Scherf and Schlachman, 1948;McNerney and Leedham, 1950), and also in a case of thyrotoxicosis (Labbe, Justin-Besanion and Gouyen, 1929b). In a survey of the literature four cases of myocardial ischaemia occurring in previously healthy migraine sufferers have been found; in two of these angina occurred (Bailey Carter, 1940;Bemreiter, 1965), one developed a probable myocardial infarct (Fuchs and Blumenthal, 1950), and one a definite infarct (Goldfischer, 1960).…”
