  • Title: [Pure arrhythmic form of the pre-infarction syndrome or spasm responsible for myocardial necrosis].

    Abstract:
    A 74 years old man was admitted as an emergency for syncopal attacks due to recurrent ventricular fibrillation (VF). These attacks were observed at the height of myocardial ischaemia as shown by ST elevation in Leads II, III and RV without associated anginal pain. Inferior myocardial infarction occurred during recurrent VF on the 4th day; the outcome was favourable. Coronary angiography was performed on the 10th day and showed double vessel disease; ergometrine (0.2 mg) induced anginal pain and ST elevation in Leads II, III and AVF. A good clinical result was obtained by calcium antagonists with an 18 months follow-up. Coronary spasm, documented in this case by the ergometrine provocation test, is now recognised as a cause of resting angina, effort angina and also some cases of myocardial infarction. This report suggests that coronary spasm may also induce apparently isolated severe ventricular arrhythmias without associated chest pain, which raises the question as to whether arrhythmias induced by spasm could play a primary role in aggravating myocardial ischaemia, leading to myocardial infarction.
