Analysis of predictors of the development of chronic heart failure in pa-tients after coronary bypass on a working heart

Abstract

Тhe article analyzes the prevalence of coronary heart disease (CHD) and its surgical treatment by performing coronary bypass surgery off-pump. The purpose of the study was to investigate echocardiography parameters in patients with CHD after off-pump coronary bypass surgery, depending on the number of shunts and their origin. The study included 521 people (416 men, 105 women), their average age was (64.2±3.4). All study participants underwent coronary bypass surgery off-pump. The article analyzes single-, two- and multi-vessel lesions of coronary arteries, paying attention to the origin of shunts. What were used during the provision of coronary bypass surgery off-pump. Attention is paid to echocardiography indicators, which are indicators of heart failure – left ventricular ejection fraction and end-diastolic volume. It has been established that coronary bypass surgery off-pump allows for the elimination of structural features (left ventricular ejection fraction, end-diastolic volume) and there are no restrictions on the number of applied shunts (distal anastomoses). Coronary bypass surgery off-pump is possible in severe clinical conditions of the patient, presence of concomitant pathology and is performed only if the operating surgeon has extensive operational experience. His assistants and the entire hearth team. Thus, it is extremely important to substantiate the indications for performing coronary bypass surgery on a working heart, taking into account the patient's personal characteristics, his age, the number of affected vessels, the structural features of the vascular bed, the functional state of the cardiovascular system and other body systems, which will allow to increase the efficiency surgical treatment of coronary heart disease, extend the duration and improve the quality of life of patients.
