The importance of determining the viable myocardium in the patients with chd and diffuse lesion of coronary arteries

Coronary heart disease is currently one of the main causes of mortality, temporary and permanent disability of the population in the developed countries of the world. The problem of treating such patients is currently aggravated by an increase in cases of detection of diffuse lesions of the coronary bed, when the usual tactics of complete direct revascularization becomes impossible. In this regard, the attention of cardiac surgeons is directed to the development of new treatment methods. In such conditions, the issue of preoperative diagnosis of the viable myocardium becomes especially relevant, which can significantly affect the choice of surgery tactics aimed at the complete restoration of myocardial perfusion of the left ventricle.
