[Myocardial revascularization in threatening extension of myocardial infarction (author's transl)]

Myocardial revascularization was performed in 13 patients between two and 14 days following initial infarction because of impending re-infarction. The diagnosis of impending re-infarction was made on the basis of the following criteria: myocardial infarction; repeated stenocardia despite medical treatment; renewed ST-T changes in the ECG. The intra-aortic balloon pump was installed in 7 patients for haemodynamic reasons (shock, massively raised pressure in the pulmonary artery). 12 patients survived the surgical intervention and were eventually discharged free of stenocardia. The presented findings suggest that surgical intervention in impending re-infarction appears of value in those cases which have not been satisfactorily controlled by conventional medical treatment.
