Goal: to investigate angiographic and clinical efficacy of percutaneous coronary interventions (PCI) on chronic total coronary occlusions (СТО) in patients with angina of low functional classes (FC) in direct and long-term period, comparatively to conservative medical treatment. Materials: 56 patients with СТО were included. Standard medical treatment was provided to all of them, everybody suffered angina FC 1-2. Left ventricle ejection fraction (LV EF) was 54±3%. 36 patients of group I underwent PCI of СТО 20 patients of group II were given conservative medical treatment. The follow-up period was 12 months. Results. In 30 patients of group I 36 attempts of PCI were angiographically and clinically successful -the absence of anginal symptoms and objective signs of myocardial ischemia. In the long-term period 21 patients of 30 had clinical success. LV EF increased to 57±4%. Long-term clinical success had 17 patients of group II, 5 patients had the decrement of angina FC by 1, 12 had initial clinical results. LV EFaccountes53,9±2,4%. There was no difference in the frequency of major adverse cardiac events between the groups. Conclusions: PCI of СТО in patients with angina of low FC improves clinical status in direct and long-term period. When isolated, angiographically unfavorable form of СТО is diagnosed, conservative treatment with effective medication in case of angina of low FC is used
