[Repeated operations in recurrent stenocardia after aortocoronary bypass]. / Povtornye operatsii pri retsidive stenoKardii posle aortokoronarnogo shuntirovaniia.

With growth of the number of primary operations and duration of the postoperative period, there was an obvious tendency towards an increase of the absolute number of patients with recurrent angina pectoris. Among 990 patients who were operated on successively during a period of 9 years, 9% had severe Functional Class III-IV angina pectoris, in whom coronary bypass graphy was indicated to determine the possibility of undertaking a reoperation. The examination was conducted in 61 patients with recurrent marked angina pectoris. Impaired patency of the aortocoronary shunts was found to be the main cause of recurrence. At present, reoperations were carried out in 18 patients, 2 years after the first operation, on the average. The authors claim the immediate results of the reoperations to be satisfactory. The hospital mortality was 5.6%.

[Effect of perioperative myocardial infarction on late results of the aortocoronary bypass]. / Vliianie perioperatsionnogo infarkta miokarda na otdalennye rezul'taty aortokoronarnogo shuntirovaniia.

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.
