RESUMO
OBJECTIVE: The aim: The purpose of the present research was to study the results of coronary artery bypass graft (CABG) surgery depending on the degree of left ventricular ejection fraction (LVEF) reduction with the aim to identify additional echocardiographic predictors of the early postoperative period. PATIENTS AND METHODS: Materials and methods: Were fixed, the results of CABG in 97 patients operated on in the "Bikard" private clinic from March 2016 to December 2018 were the material of the research. All patients underwent CABG surgery under cardiopulmonary bypass and cardioplegia, and in the preoperative period underwent echocardiographic examination according to the standard technique on the Vivid 7 machine. Patients, in dependent of the LVEF, were divided into 3 groups: group 1 35 people (LVEF < 40%), group 2 32 people ( 40% < LVEF < 50%), group 3 30 people (LVEF > 50%). RESULTS: Results: Our studies showed that the most important echocardiographic predictors of a complicated development of the disease in the early postoperative period, in addition to LVEF of the heart, can be the size of the left ventricle and left atrial, the presence and severity of mitral regurgitation and diastolic dysfunction of the left ventricle of the heart. CONCLUSION: Conclusions: Comprehensive measurement of these echocardiographic parameters will allow more accurately predict the results of coronary artery bypass grafting in the early postoperative period.
