Coronary artery bypass grafting is a widely used cardiosurgical intervention which may be performed either on the arrested heart in conditions of artificial circulation or on the beating heart without artificial circulation. However, in a series of works, the results of bypass grafting using both techniques had no significant differences.

In our article, we analyse the flowmetric parameters of blood flow through the coronary bypass grafts in high-surgical risk patients presenting with ischaemic heart disease and undergoing coronary artery bypass grafting in conditions of artificial circulation and on the beating heart. For this purpose, a total of 148 patients enrolled into the study were divided into 2 groups depending on the technique of surgical treatment.

The obtained statistical data showed comparable results in the both groups, however, operative interventions on the beating heart made it possible to significantly decrease the risk of the development of the majority of complications.

KEY WORDS: ischaemic heart disease, coronary artery bypass grafting, high surgical risk, ultrasound flowmetry, blood flow velocity, artificial circulation.
