[Coronary angiography in the pre-infarct syndrome (author's transl)].

During the first ten month of the past year (1974) we did 310 selective coronary arteriographies by the Sones technique at the Department of Cardiology of the Medical Clinic Würzburg. The incidence of complications in this comparatively small group was 0%. In seven cases we did an emergency coronary arteriography. Six of these patients were transferred immediately after examination to the Department of cardiac Surgery of the University of Erlangen for emergency aortocoronary vein bypass. One of these patients died within the next 6 hours postoperatively. Five patients in this group are in good condition. Three patients had a double aorto-coronary vein bypass.
