Relevance. Through dermal coronary intravascular revascularization by means of stenting is an effective method of treatment CHD patients with the type 2 diabets. At the same time frequency of stents restenosing for this special cohort of patients is fluctuating from 12 by 40 %.Objective. To study prognostic significance of the new biomarker of intravascular inflammation of resisin in blood of CHD patients with DM 2 who suffered from stenting. Material and methods. In the study 60 patients (48 men and 12 women, in the middle age 60.9 years) with CHD and DM2 are included. The patients were divided into two groups: Patients with positive progress of comorbide pathology belonged to the first group (n = 30); in the second group (n =3 0) patients with unfavorable progress of cardiac vessel pathology were included. The further observation was carried during 12 months. Content of all the patients in blood of resistin with help of enzyme immunoassay analysis was determined, as well as lipid blood serum mixture and additional metabolic risk factors. By the indications control a coronary angiography was conducted. Restenosis of coronary arteries was counted as the narrowing of a coronal artery lumen of ≥70% in the place of an intervention.The result. Unfavorable flow, including restenosis of coronary arteries was revealed in 30 cases (50%). ROC-analysis showed great predictive significance of resistin – (area under a curve >5/35, Sensitivity 86.2, Specificit 70.0) in development of constrictive coronary atherosclerosis restenosis of coronary arteries after their stenosis.The conclusion. The study of resistin level in DM patients blood for the valuation of the disease prognosis and optimization of the tactics for choice of coronary pathology treatment seems expedient and informative.

The research objective is to determine the posterior probability of adverse cardiovascular events after elective coronary intervention in patients with ischemic heart disease (IHD) associated with type 2 diabetes, at high level of lipoprotein-associated phospholipase A2 (Lp-PLA2) in blood serum, as well as to find out the optimal separation point value for this predictor, which increase allows to identify high risk with accuracy.Material and methods. The 12-month cohort observational study included 60 patients (78% of men and 22% of women) with IHD associated with type 2 diabetes, aged 48–78. At the beginning of the study, along with conventional diagnostic techniques typical of a specialized cardiology clinic, the state of carbohydrate and lipid metabolism was analyzed and the proinflammatory status was evaluated (including assessment of Lp-PLA2 concentration by ELISA). At the end of the study distant results of treatment were assessed. The following events were taken into account: death of cardiovascular events, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization (surgical, endovascular) due to restricture formation of a primary implanted stent or stricture formation of native coronary arteries, angina pectoris relapses.Results and discussion. The link between adverse cardiovascular events after elective percutaneous coronary intervention in patients with IHD type 2 diabetes-associated and high concentration of Lp-PLA2 in blood serum has been identified. Variation of the decision rule threshold on the performance curve has allowed to take Lp-PLA2 concentration of 983 ng/ml as a separation point. Accuracy of twoclass classification (determination of the posterior probability of adverse cardiovascular events) after identifying such separation point was characterized by 80% sensitivity and 100% specificity.Conclusion. The increase in the Lp-PLA2 concentration in blood serum (>983 ng/ml) may be considered as a predictor of adverse cardiovascular events after elective percutaneous coronary intervention in patients with IHD associated with type 2 diabetes.

The aim of the study was to evaluate dynamics of heart rhythm variability (HRV during a1, b1, and b2-adrenoblockade by carvedilol in patients with coronary heart disease (CHD) and recurrent angina pectoris treated by endovascular revascularization. The study included 39 men (mean age 57.5 +/- 0.8 years) who underwent stenting of coronary arteries (CA) 6 month or more before the study. For the purpose of analysis, patients with CA restenosis were allocated to group 1 (n = 17), those without restenosis or complaining of chest discomfort in the absence of restenosis during repeated coronaroventriculography comprised group 2 (n = 22). Patients having no complaints were followed up by coronarography 1 year after stenting. HRV was estimated from the analysis of short (15 min) fragments of the standard ECG obtained in the basal state and during a1, b1, b2-blockade by carvedilol (mean dose 22.88 +/- 2.1 mg/day) for 2 weeks. Carvedilol blockade of a1, b1, b2-adrenoreceptors following coronary stenting significantly improved both temporal and spectral components of HRV. This improvement may serve as an independent marker of revascularization efficiency and an earlier predictor of coronary restenosis or reflect progress of the atherosclerotic process in native arteries.

The aim of this work was to evaluate anti-ischemic and angiographic efficiency of endovascular revascularization of ischemic myocardium by implantation of Sirolimus-eluting stents from the results of a 18 moth-long prospective study of patients with coronary heart disease and/or type 2 diabetes mellitus (DM). The study included 108 patients with angina of effort randomized into two groups: CHD with DM (n = 51) and CHD without DM (n = 57). All of them received anti-ischemic and antihypertensive therapy and two desaggregants; DM patients also used oral hypoglycemic preparations. The patients underwent implantation of Sirolimus-eluting stents. The frequency of restenosis of the target arteries, development of serious cardio-vascular events (death, MI, cerebral stroke, and the need in repeat revascularization) were compared within 18 months after primary endovascular revascularization. Although Sirolimus-eluting stents markedly improved long-term prognosis in DM patients, results of their implantation were worse than in patients with CHD without DM.

AIM:To study long-term results of 3-42-month (mean 18.1 +/- 1.2 month) of a prospective clinically and angiologically controlled follow-up after coronary endovascular revascularisation with sirolimus-eluting stents (SES) in patients with coronary heart disease (CHD) comorbid with type 2 diabetes mellitus (DM).MATERIAL AND METHODS:A total of 108 CHD patients with angina pectoris resistant to antianginal therapy were divided into 2 groups: 51 CHD patients with mild and moderate type-2 DM (group 1); 57 CHD patients free of diabetes (group 2). All the patients have undergone successful coronary endovascular revascularisation with SES. Anti-ischemic efficacy and safety of stenting were studied in the course of 18-month prospective follow-up.RESULTS:An anti-ischemic effect of stenting in hospital setting was achieved in all the patients. 18 months after stenting frequency and severity of anginal attacks reduced in group 1 by 70.6%, daily need in nitroglycerine--by 71.9%, in group 2--by 87.1 and 93.1%, respectively. As a result, exercise tolerance improved in group 1 by 38.3%, in group 2--by 40.8%. Quality of life improved by 22.7 and 25.1%, respectively. Most of the patients showed no deterioration of carbohydrate and lipid metabolism compensation. Recurrent angina and symptoms of painless myocardial ischemia occurred in 39.3 and 14% patients of group 1 and 2, respectively. More frequent causes of the recurrence were progression of coronary artery atherosclerosis de novo and Cypher stent restenosis (11.8 and 3.5% in group 1 and 2, respectively).CONCLUSION:SES implantation provided good anti-ischemic efficacy in 60.7 and 86% CHD patients with and without DM, respectively. It significantly improved exercise tolerance and quality of life.

Aim. To evaluate effects of 6-month therapy with losartan in combination with indapamide on a clinical course, immunological, metabolic parameters, left ventricular function, exercise tolerance and quality of life in patients with coronary heart disease (CHD) associated with metabolic syndrome (MS). Material and methods. Forty six CHD patients with postinfarction cardiac dysfunction in MS were randomized into two groups. Group 1 consisted of 22 patients with impaired glucose tolerance, group 2 - of 24 type 2 diabetics. Treatment included combination of losartan (50 mg/day) with indapamide (1.5 mg/day), on demand nitrates, nebivolol. Basic therapy in diabetes included sugar-reducing drugs. Clinical condition, findings of echocardiography, parameters of lipid and carbohydrate metabolisms, immunoglobulins, circulating immune complexes, autoantibodies to cardiolipin (AB to CL), spectrum of proinflammatory cytokines were studied before and 3 months after course treatment. Results. Overactivation of cytokines (primarily IL-2, IL-1, TNFalpha) with high expression of IgA, IgG, CIC, AB to CL was found in CHD patients with type 2 diabetes mellitus and less evident in impaired glucose tolerance. Losartan in both groups had an antihypertensive effect, stabilized LV hypertrophy, improved clinical symptoms leading to cytokines expression decline: TNFalpha by 9.8%, IL-1 - by 6.1%, IL-6 - by 6.7%. Losartan was well tolerated, caused no negative metabolic effects. Conclusion. New original facts of cytokine overactivation and humoral immunity disturbances were discovered which play an essential role in pathogenesis of postinfarction dysfunction and LV remodeling developing in type 2 diabetes mellitus. Losartan 6-month treatment in the fixed combination has a positive effect on clinicohemodynamic and immunometabolic indices. This gives grounds for wider use of losartan in CHD combined with type 2 diabetes mellitus.

Anti-ischemic, cardioprotective, hemodynamic and metabolic affects as well as influence on regress of insulin resistance microcirculation injuries of valtarsan which was used in combination with tiasid diuretics hydrochlortiasid were studied in the secondary prevention of chronic heart failure in patients with left ventricular postinfarction remodeling, ischemic cardiac dysfunction aggravated with the diabetes mellitus of the 2-nd type. The study included 25 patients aged 59,2±5,8 years. Results of 3-months treatment with these drugs revealed their high anti-ischemic and cardioprotective efficacy. The study results showed markedly increased physical tolerance and quality of life of such patients.

Aim. To evaluate clinico-immunological disorders in patients with ischemic heart disease (IHD) and metabolic syndrome (MS), to study an immunocorrective action of nebivolol during 6-month treatment. Material and methods. A total of 54 patients with postinfarction left ventricular dysfunction and chronic cardiac failure of NYHA functional class II-III were divided into two groups: group 1 (n = 24) comprised patients with effort angina FC II-III and impaired glucose tolerance, group 2 (n = 30) consisted of anginal patients associated with type 2 diabetes mellitus (DM). Clinical, laboratory and functional indices were registered before therapy with nebivolol and 6 months after it. Immunological control included determination of the subpopulation composition of lymphocytes, immunoglobulins, circulating immune complexes (CIC), antibodies to cardiolipin (CL), proinflammatory cytokines: IL-1alpha, IL-2, IL-6, IL-8, alpha-interferon, tumor necrosis factor alpha (TNFa). Results. Nebivolol demonstrated good antihypertensive and anti-ischemic cardioprotective efficacy in IHD patients with MS, it did not deteriorate atherogenic dyslipidemia and impaired carbohydrate metabolism. As a good immunocorrector, nebivolol significantly inhibited cytokine overactivation, had a weak effect on dysimmunoglobulinemia, CIC level and expression to CL antibodies. Side effects were not recorded. Conclusion. IHD patients with MS (especially patients with type 2 DM) have manifest immune disorders presenting with overactivation of proinflammatory cytokines with high levels of IgA, IgG, CIC and antibodies to CL in the presence of low immunoregulatory index. Nebivolol provided good control of arterial hypertension, myocardial ischemia, positive changes in immunological indices, improved intracardiac hemodynamics.

Aim. To characterize clinical and immune disorders in patients with ischemic heart disease (IHD), postinfarction left ventricular remodeling (PLVR), clinical manifestations of chronic cardiac failure (CCF).Material and methods. A comparative clinical controlled trial of immune system was made. The immune system was assessed by diagnostic and prognostic significance of changes in population composition of T- and B-lymphocytes, by activation of proinflammatory cytokines (IL-1alpha, IL-2, IL-6, IL-8, Inf-alpha, TNF-alpha); high expression of circulating immune complexes (CIC), autoimmune complexes to cardiolipin (CL) in 94 CCF patients with PLVR. The patients were divided into 3 groups according to severity of CCF. Group I consisted of 32 patients with CCF (FCII by NYHA) and normal ejection fraction (EF) of the left ventricle (52.0 +/- 2.8%). Group 2 - 31 CCF (FCIII) patients with decreased EF (by 43.8%) (36 +/- 4.3%). Group 3 - 31 CCF (FCIV) patients with low (25 +/- 3.8%) EF of the left ventricle. The protocol required conduction of echocardiographic parameters, paired bicycle exercise tests, 6-min walk tests, 24-h ECG monitoring, population cell composition of T- and B-lymphocytes, concentrations of cytokines, IgG and IgG autoantibodies to CL.Results. A dominating hyperactivation of cytokines TNFalpha, IL-1alpha, IL-2, IL-6 with high expression of CIC and autoAB to CL was associated with moderate or severe CCF (FCII-IV by NYHA), declined inotropic function of the left ventricle (EF 38-23%), low exercise tolerance and remodeling of the left ventricle.Conclusion. Immune disorders in the form of hyperactivation of proinflammatory cytokines (most of all TNFalpha, IL-]alpha, IL-2, IL-6), enhanced expression of CIC and autoAB to CL growing with severity of CCF and abnormal heart pump function play an important role in CCF pathogenesis in IHD patients with LCPR and can be markers of the disease progression.

AIM:To study safety and effects of nebivolol on the course of coronary heart disease (CHD) and insulin resistance (IR) in patients with diabetes mellitus type 2 (DM-2) after coronary artery bypass grafting.MATERIAL AND METHODS:The study included 53 CHD patients with DM-2 (mean age 56.7 +/- 1.3 years). All the patients were divided into two groups: 22 patients with IR (group 1) and 31 patients free of IR (group 2). All the patients received an 8 week course of nebivolol the efficacy of which was assessed by changes in coronary failure, exercise tolerance, quality of life, lipid and carbohydrate metabolism.RESULTS:In group 1 an antianginal effect of nebivolol manifested with less frequent (by 54.7%) development of angina pectoris (p = 0.0003), a 59.8% (p = 0.0004) decrease in 24-h need in nitroglycerine. In group 2 these reductions were 63.4 and 61.6% (p < 0.01), respectively. Exercise tolerance increased by 36.2 and 25.2%, left ventricular ejection fraction significantly increased by 5.9 and 5%, respectively, quality of life improved by 25 and 23%, respectively. As a result, a functional class of chronic cardiac failure lowered. Nebivolol had no negative effect on compensation of blood lipid and carbohydrate metabolism. A trend to blood insulin fall by 18.4% was found. IR index diminished by 11.9%.CONCLUSION:Administration of nebivolol in a dose 1.25-5 mg/day raised exercise tolerance, improved quality of life, reduced IR index by 11.9%, triglycerides level by 5.3%. This lowered the risk of effects of diabetic atherogenic dyslipidemia.

A three-year follow-up of patients with coronary heart disease (CHD) and type II diabetes after coronary artery bypass grafting, shows that the following pathologic conditions are significantly more frequent: arterial hypertension, visceral obesity, marked disturbances of blood lipid spectrum, an increases CHD duration, and an increased rate of myocardial reinfarction and revascularizations. The study shows that the presence of diabetes mellitus in CHD patients undergoing coronary artery bypass grafting, is associated with pronounced disturbances in blood lipid spectrum, and is an important risk factor of coronary event progression.

The purpose of the study was to evaluate anti-ischemic and metabolic effects of the cardioselective beta-adrenoblockers nebivolol and retarded metoprolol-metaprolol CR/XL (betalok ZOK) in patients with postinfarction heart dysfunction, associated with type II diabetes mellitus (DM). 40 patients with coronary heart disease (CHD), functional class (FC) II-III exertional angina, postinfarction left ventricular (LV) dysfunction, and NYHA FC II heart failure, associated with type II DM, were randomized into 2 groups. The 20 patients of the 1st group were administered nebivolol in a dose of 1.25 to 5 mg per day, the 20 patients of the 2nd group - betalok ZOK in a dose of 12.5 to 100 mg per day. The course therapy lasted 8 weeks. The effects of the treatment were evaluated using paired veloergometry, echoCG, and lipid spectrum analysis. The study found that nebivolol in a mean dose of 4.2 +/- 0.3 mg per day and betalok ZOK in a dose of 46.5 +/- 6.2 mg per day reduced the frequency and severety of angina attacks (by 73.8% and 67.8%, respectively) and daily nitroglycerine uptake (by 78.6% and 69.1%, respectively), and increased activity tolerance (by 7.9% and 25.3%, respectively). None of the preparations displayed any adverse effects on carbohydrate exchange and blood lipid spectrum. Nebivolol, unlike betalok ZOK, significantly (p = 0.02) reduced triglyceride blood level by 29%. Thus, the new generation cardioselective beta1-adrenoblockers nebivolol and metoprolol CR/XL (betalok ZOK) provide anti-ischemic and metabolic effects in patients with CHD and postinfarction LV dysfunction, associated with type 2 diabetes mellitus. Nebivolol is preferable as far as blood lipid spectrum is concerned.
