Abstract

Objective: to assess the condition of patients with return of myocardial ischemia after CABG, causes and timing of emergence of recurrence of angina, the effective functioning of the arterial and venous conduits.

Material and methods. The study includes a retrospective and prospective analysis of the status of partially 756 patients with clinically proven recurrence myocardial ischemia after CABG surveyed during the period from January 2009 until December 2018 year. Analysis of the clinical status of patients was carried out depending on the time of recurrence of myocardial ischemia, the type used by the conduits and the primary operation CABG.

Results. Randomization of patients depending on the time of recurrence of myocardial ischemia after CABG was as follows: Group I – relapse recurrence of myocardial ischemia in one form or another has been observed in the period from 1 month to 1 year after CABG, group II – return clinic myocardial ischemia diagnosed in time from 1 year up to 5 and III group – clinic return of myocardial ischemia diagnosed in a period exceeding 5 years after CABG. Next, we assessed the patency of coronary 2098 shunts.

Conclusion. According to 140 (89.7%) arterial and 208 (67.7%) venous shunts were passable in Group I; 233 (87.9%) arterial and 225 (51.3%) venous shunts were passable in II Group; and 335 (88.8%) arterial and 232 (41.8%) venous shunts were passable in Group III. These features will in the future be planned carefully using those or other conduits depending on anatomy practically all stages of CABG frequency insolvency venous shunts higher frequencies insolvency shunts of the internal mammary artery and radial arteries.
