Patients with stable angina of no more than II functional class, old myocardial infarction, occlusion of middle segment of left anterior descending artery with proved myocardial viability in the vascular bed of affected artery and ejection fraction < 40% were included in the restrospective study. Indication for surgical remodeling of left ventricle and valvular interventions was the criteria for exclusion from the study. 39 patients after successful endovascular interventions with "major" complications were included in group 1. 44 patients undergoing only pharmacologic treatment were included in the group 2. Patients in both groups were comparable in their clinical and angiographic characteristics. After 12 months of observation in group 1 and 2 accordingly mortality amounted 5.1 and 2.3% (p=0.92), incidence of myocardial infarction (MI) - 7.7 versus 4.5 % (p=0.89); angina relapse (including recurrent or primary myocardial revascularizations) was observed accordingly in 17.9 and 2.3% of patients (p=0.041); acute stroke - in 2.6 and 2.3% (p=0.53); total amount of complications concluded 33.3 and 11.36% in group 1 and 2 (p=0.031). After 36 months of observation in group 1 and 2 accordingly mortality amounted 10.3 and 6.8% (p=0.87), incidence of myocardial infarction (MI) - 10.3 versus 9.1% (p=0.87); angina relapse (including recurrent or primary myocardial revascularizations) was observed accordingly in 28.2 and 13.6% of patients (p=0.17); acute stroke - in 5.1 and 2.3% of patients (p=0.91); total amount of complications concluded 53.8 and 31.8% in group 1 and 2 (p=0.031). After 60 months of observation in group 1 and 2 accordingly mortality amounted 12.8 and 11.4% (p=0.89), incidence of myocardial infarction (MI) - 12.8 versus 13.6% (p=0.85); angina relapse (including recurrent or primary myocardial revascularizations) was observed accordingly in 30.8 and 15.9% of patients (p=0.18); acute stroke - in 5.1 and 2.3% of patients (p=0.53); total amount of complications concluded 61.5 and 43.2% in group 1 and 2 (p=0.147). Statistically significant difference in survivability between groups was not revealed during the 5 years of observation. It is drawn a conclusion that re-canalization and stenting of chronic coronary occlusions in this category of patients at least don't worsens prognosis in comparison with pharmacologic therapy.
