[Perioperative myocardial infarct in association with surgical treatment of coronary heart disease].

Perioperative myocardial infarction is a major complication of revascularization surgery of the heart which can negatively affect both the quality and duration of the patient's life. The aim of the paper is to contribute to the understanding of the problem which involves the definition, incidence, pathogenesis, diagnosis, complications, therapy and prognosis of perioperative myocardial infarction. One of the basic factors implicated in the development of perioperative derangement of the cardiac muscle is closely analyzed, namely insufficient protection of the myocardium with subsequent ischemia-reperfusion induced myocardial damage. Pitfalls of electrocardiographic diagnosis are pointed out and the rather complicated interpretation of increased enzyme levels following cardiac surgery is discussed. Complications, management, as well as early and late prognosis of patients with perioperative myocardial infarction are also dealt with.
