Features of surgical treatment of ischemic heart disease in patients with the expressed dysfunction left ventricular

Abstract

Objective: to study the effect of intraluminal coronary shunts to immediate results of surgical treatment of ischemic heart disease in patients at high surgical risk with a reduced fraction of left ventricular ejection. Materials and methods: a retrospective analysis of case histories of 96 patients with coronary heart disease and decreased ejection fraction of the left ventricle who underwent surgery coronary artery bypass grafting. The patients were divided into 2 groups: the study group included 47 patients operated in the parallel artificial blood circulation, which when performing the distal anastomoses used temporary intracoronary shunts; the control group comprised 49 patients, also operated in the parallel artificial blood, but when performing distal anastomoses did not use intracoronary shunts. Monitoring of patients was performed until 12 months after surgery. Results: both groups of patients were matched for clinical and demographic indicators. In the analysis of intraoperative and postoperative period revealed the difference in the incidence of cardiac arrhythmias, other parameters were comparable. Conclusions: thus, in patients with reduced ejection fraction left ventricular intracoronary shunts is advisable to use for reasons and not in all cases, operations myocardial revascularization in the parallel artificial circulation.
