[Surgical treatment and prevention of myocardial infarct]

In modern surgery of coronary arteries both surgical therapy of early stages of acute infarction and its surgical prophylaxis in preinfarction conditions seem to be quite feasible. 100 consecutive operations for ischemic heart disease are analysed. The principal type of surgery is a mammary coronary anastomosis. Among the mentioned patients one had a progressive acute myocardial infarction, resulting in death, and 14 patients were in primary preinfarction conditions. A surgical classification of acute disturbances in coronary circulation is described. Marked segmental stenoses of large coronary vessels underlie preinfarction status. Mosaic electrocardiotopography is of great value in recognition of preinfarction conditions. An early recognition and urgent surgical intervention are absolutely necessary in preinfarction state patients.
