“…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). A further complication of the use of ergotamine for migraine is that the drug itself may cause headache, and this may lead to an increase in dose by the patient, and the establishment of a vicious circle (Wainscott, Volans and Wilkinson, 1974).…”
