Abstract: the article presents the results of a comparative analysis of the dynamics of the functional parameters of the left ventricle (LV) of 138 patients with coronary artery occlusion after incomplete (palliative; IMR – the main group – 62 people) and complete myocardial revascularization (CMR – control group – 76 people). The implementation of IMR provided for correction of only significant neoclusal lesions, CMR – restoration of the occluded artery and correction of stenoses of other coronary arteries. As clinically significant the indicators were considered that describe the LV function: ejection fraction, an index violation of local contractility, diastolic function. After 12 months after the interventions, LV function was fully normalized in 34.5% of patients of the IMR group and 58.0% of the CMR group, in both groups a significant increase in patients with only one indicator was determined. It was concluded that the results of complete and palliative myocardial revascularization were comparable in terms of restoring myocardial functions and increasing the life expectancy of patients with limited possibility of endovascular recanalization of coronary occlusions.
