Autologous Bone Marrow Mononuclear Cells in the Combined Treatment of Coronary Heart Disease

EuroScoreII is intended to assess the risk of adverse outcome of coronary artery bypass grafting. Assessment factors: age, sex, serum creatinine, extracardiac artery disease, chronic lung disease, severe neurological disorders, previous cardiac surgery, previous myocardial infarction, left ventricular dysfunction, diabetes mellitus, pulmonary hypertension, IV class of angina severity, active endocarditis, unstable angina, surgery, critical condition of the patient before surgery, type of surgery. The higher the percentage, the higher the risk of surgery.

The results were obtained from the analysis of primary data.

Assessment of the severity of the systemic inflammatory response during hospital stay after surgery. Assessment of the level of inflammation by the severity of an increase in leukocytes (leukocytosis).

Leukocytosis - an increase in the number of leukocytes per unit volume of blood. The norm of leukocytes in the blood is 5.5-8.810^9 /l. For adults, leukocytosis is considered to be an increase in the number of leukocytes in the blood of more than 9.0*10^9 / l In the statistical analysis, the grouping of indicators in the indicated intervals was used, in view of the individual characteristics of the course of the postoperative period in each case.

Results of dynamic control of laboratory parameters of CRP. C-reactive protein. This fraction of plasma proteins increases in the presence of an inflammatory process in the body. It is synthesized in response to the ingestion of toxins of pathological microorganisms into the bloodstream and neutralizes them by binding them. In addition, it appears when the body's own cells are destroyed in the event of necrosis, tumor disintegration or extensive trauma, inactivating the resulting products. In addition to eliminating toxins, CRP triggers a cascade of immune responses aimed at eliminating pathologically altered structures.

Normally absent (or less than 0.4 mg / l). In the statistical analysis, the grouping of indicators in the indicated intervals was used, in view of the individual characteristics of the course of the postoperative period in each case.

A daily assessment of the discharge by drainage before removal was carried out. It was carried out to assess the possible development of an excessive inflammatory reaction (polyserositis phenomena) in response to the transplantation of autologous bone marrow mononuclear cells.

Assessment of the severity of the period of ischemia / reperfusion. And the effect of autologous bone marrow mononuclear cells transplantation on these indicators.

Estimation of the time from the moment the clamp is applied to the aorta (complete clamping of the aorta) to the removal of the clamp from the aorta.

The presence of complications in the postoperative period (Hydrothorax, Hydropericardium, Cardiac arrhythmias - atrial fibrillation / atrial flutter).

Evaluation of myocardial contractility according to echocardiography, in particular the left ventricular ejection fraction, was carried out within 7-14 days of the postoperative period, depending on the patient's clinical condition, as well as the maximum degree of information content of this study. The lower the indicator, the worse the prognosis of an unfavorable outcome.

Assessment of myocardial contractility according to echocardiography, in particular the size of the left ventricle - its index, was carried out within 7-14 days of the postoperative period, depending on the clinical condition of the patient, as well as on the maximum information content of this study. The higher the indicator (left ventricular size - index), the worse the prognosis of an unfavorable outcome.

The index is used as an indicator of payment to obtain a more reliable result (taking into account the individual characteristics of each patient).

The need to perform defibrillation to restore sinus rhythm, at the end of the main stage of surgery.

The total number of deaths - in the primary hospitalization and during the observation period of 12 months after surgical treatment - deaths associated with the progression of the initial disease.

The complication rate for CABG operations is 30±10%. According to n1=kn2; n1 sample size, in the control. In group 0, k=2/3 times more than in group 1 and group 2. The difference between the test and control frequencies is ε=p1-p2. Accordingly, with p1 = 0.2; p2=0.4, δ= 0.1; n1=49.5, n2=33. The result is group 0 - 36, group 1 and 2 - 25+25 = 50. The null hypothesis of complication rate δ.All patients included in the study.

The SF-36 questionnaire. The indicators of each scale vary between 0 and 100, where 100 represents total health. The results are presented in the form of scores on 8 scales, compiled in such a way that a higher score indicates a higher level of quality of life.MHFLQ - for patients with heart failure.The specified questionnaire consists of 21 questions. To answer each question, a scale of 6 points from the minimum intensity of certain symptoms to the maximum is used. The assessment is based on the sum of points, where the maximum number of points - 105 corresponds to the patient's worst condition. The lowest score 0 points is the best clinical condition of the patient. SAQ consists of 19 questions about the patient's condition, which are divided into the following 5 scales. The quality of life for each of the five scales under consideration is measured in percent, with 0% corresponding to the worst quality of life, and 100% to the best.

• functional class - The usual load does not cause changes in the state of health. Painful attacks occur against the background of excessive loads - after climbing several flights of stairs, while walking fast.
• functional class - Pain attacks when walking more than 500 meters, when climbing stairs more than one floor.
• functional class - The patient does not tolerate minimal physical activity. An attack occurs when walking a distance of 50-100 meters. Climbing stairs is difficult.
• functional class - Activity is significantly limited. Angina pectoris manifests itself when performing minimal actions, including at rest.

• functional class - There is no limitation of a person's physical activity, shortness of breath manifests itself when going above the third floor.
• functional class - slight limitation of activity, palpitations, shortness of breath, fatigue occur during normal physical activity and more.
• functional class - Symptoms occur with the smallest physical activity, resulting in a significant decrease in activity. At rest, clinical manifestations are not observed.

The smaller the functional class, the better the quality of human life.

Evaluation of left ventricular diastolic function (echocardiography). The peak velocity E reflects the pressure gradient between the LA and LV in early diastole, and it is affected by preload and disturbance LV relaxation The speed of peak A, which forms at the end diastole, influences LV compliance and contractility left atrium.

The ratio of the transmitral flow, wave E (ejection wave / left ventricular contraction) to wave A (ejection wave / left atrial contraction). The norm is 0.75-1.5 Less than 0.75 violation of relaxation, more than 1.5 restrictive type of diastolic dysfunction.

Echocardiographic data ( DT (Half-time of wave E), time of isovolumic relaxation of the left ventricle (IVRT).

DT (Half-time of wave E). The DT time index reflects the relaxation process LV, LV diastolic pressure after mitral valve opening, and LV compliance. 150-200 ms - normal; > 200 ms - violation of relaxation; 150-200 ms - pseudonormal type of left ventricular filling; <150 ms - restrictive type of diastolic dysfunction IVRT (time of isovolumic relaxation of the left ventricl.) <100 ms - normal; > 100 ms - violation of relaxation

The dynamic of the number of meters walked according to the 6-minutes walk test (6MWD) in the observation groups.

According to the angiographic study.

Echocardiographic data.

Dependence and Duration of Positive Clinical Effect on the Amount of Injected Cell Material (cytosis).

Dependence and duration of positive clinical effect on the amount of injected cell material (Mononuclear fraction %, CD34+ %, CD133+ %).

Assessment - mononuclear fraction, CD 34 +, CD 133+ according to flow cytometry data.

The distance covered (in meters) was compared with the proper value depending on age (years), height (cm), weight (kg), body mass index (BMI). The due values (6MWD (i)) were calculated using the following formulas: For men: 6МWD (i) = 7.57 × height - 5.02 × age - 1.76 × weight - 309 or 6MWD (i) = 1140 - 5.61 × BMI - 6.94 × age. For women:

6МWD (i) = 2.11 × height - 2.29 × weight - 5.78 × age + 667 Or 6МWD (i) = 1017 - 6.24 × BMI - 5.83 × age. This difference at baseline is reported as distance walked for smokers minus non-smokers.
