STIMULATION OF EXTRACARDIAL REVASCULARIZATION DURING CORONARY BYPASS SURGERY IN PATIENTS WITH DIFFUSE CORONARY ARTERY DISEASE

Abstract

Objective: Clinical observations of the use of complex myocardial revascularization (YurLeon III technique) and traditional coronary artery bypass graft (CABG) in patients with diffuse atherosclerotic lesions of the coronary network are presented. A year after CABG+YurLeon III surgery, left ventricular ejection fraction (LVEF) increased from 45% to 57%, the perfusion defect according to synchro-single-photon emission computed tomography (synchro-SPECT) decreased from 30% to 5%, the overall index of total physical well-being increased from 23.81 to 53.97 and general mental well-being elevated from 46.97 to 47.57 points. With isolated CABG, the patient had an improvement in contractility, perfusion, and key indicators of quality of life (QoL) in the early stages after surgery. However, the dynamics after a year revealed a slight decrease in LVEF, and an increase of the zone of myocardial perfusion defect.
