[Effect of perioperative myocardial infarction on late results of the aortocoronary bypass].

The article deals with the results of examination of 47 patients with a history of perioperative myocardial infarction after aortocoronary shunting and the findings in 358 persons of the control group who were operated on without this complication. The authors studied the dynamics of changes of the patients' functional condition after aortocoronary shunting, complicated by perioperative myocardial infarction in the late-term postoperative period. A comparative study was conducted of the dynamics of changes of the symptomatic status and the incidence of postoperative myocardial infarction among patients with and those without the complication. Its effect on the occurrence of the clinical picture of chronic circulatory insufficiency was also studied. A search was undertaken in this group for risk factors of the development of recurrent angina pectoris, myocardial infarction, and symptomatology of chronic circulatory insufficiency in the late-term postoperative period. The results of the study showed that perioperative myocardial infarction in the late-term postoperative period does not affect the patient's "character" of life. In the late-term postoperative period symptoms of chronic circulatory insufficiency are encountered in patients with perioperative myocardial infarction, as a rule, in a recurrence of angina pectoris and develop significantly more frequently in initial multiple affection of the coronary arteries.
