RESUMEN
An experience with using autologous bone marrow mononuclears for regeneration of the heart was analyzed in 97 patients in whom the intracoronary transplantation of autologous mononuclear bone marrow cells was performed. The results were estimated in terms up to 5 years and compared with a group of 37 patients who underwent only conservative treatment. A distinct positive dynamic of clinical and echocardiographic indices in the main group was noted in a subgroup of patients with a decreased ejection fraction (EF less than 50%) as compared with an analogous subgroup of patients in the control group. Substantial influence is exerted by regeneration therapy upon remote lethality. Thus, as a whole in the main group lethality over 5 years was 13.4% and in the group of control it was 21.6%. In the subgroup with a decreased ejection fraction and symptoms of heart failure lethality was 22.6% in the main group and 54.5%--in the control group. The intracoronary administration of the autologous bone marrow mononuclear fraction to inoperable patients with ischemic heart disease and a severe lesion of the coronary arteries and a decreased ejection fraction of the left ventricle is a safe and useful procedure resulting to substantially decreased lethality followed-up during 5 years against the background of conservative treatment.

The main group included 17 patients with distal lesion of the coronary bed in whom the performance of complete direct myocardium revascularization was not possible. The autologous bone marrow mononuclears were administered to the main group patients at the period from 2008 to 2010. The control group consisted of 10 patients given standard medicamentous therapy. A year later in the main group patients there was a decrease of median of the functional stenocardia class, median of metabolic units by the data of loading tests, median of the number of nitroglycerin pills for a week taken by the patients as compared with the control group. By the data of OECT and PECT a year later in the main group there was an improved perfusion in all the myocardium segments. In the control group on the contrary there was negative dynamics in all the indices in question.
