Influence of carbohydrate metabolism disturbance depending on expressiveness, degree of severity and type of glucose lowering therapy to current of ischemic heart disease are presented in article. Acute coronary syndrome outcomes to Q-forming and non-Q-forming myocardial infarction, unstable stenocardia, and complications to acute left ventricular aneurysm, frequency of progress pulmonary edema were analyzed in patients with normal and impaired carbohydrate metabolism.

Objective: to evaluate the severity of immuno-inflammatory responses under stable stenocardia in patients with ischemic heart disease (IHD). Patients and intervention: the study included 83 patients suffering from IHD. Among them 30 cases were diagnosed as functional class (FC)-II stenocardia, 27 cases as FC-III stenocardia and 26 cases as FC-IV stenocardia. The control group included 25 healthy persons. For characterizing the immuno-inflammatory responses we examined the level of C-reactive protein (CRP), pro-inflammatory (IL-1b, IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines by the immunoenzymic procedure. Results: FC-II stenocardia showed normal levels of CRP and pro-inflammatory cytokines. FC-III stenocardia was associated with a moderate increase in markers of an inflammation. FC-IV stenocardia was characterized by maximum levels of CRP and pro-inflammatory cytokines. Conclusion. The intensity of immuno-inflammatory responses depends on more or less serious course of stenocardia in patients with IHD.

Statins, the most common drugs to lower lipid levels, are «strategic» products for the treatment of patients with coronary heart disease (CHD), atherosclerosis, having the ability to reduce the cardiovascular and total mortality. This class of drugs can slow down the course of atherosclerosis and makes it more benign. A special place among statin places rosuvastatin (Crestor®, «AstraZeneca») due to his number of advantages of pharmacological and clinical properties. Compared with other statins, he has a far more powerful inhibition of the enzyme by metansulfonilamidnoy group and the most hypolipidemic activity (reduction of LDL cholesterol by 45–50% from baseline) in combination with the good tolerability and economic advantages.

The article is a review of modern data about quantity of smoking people in the whole world and in Russia, in particular among physicians. The influence of smoking on cardiovascular system, its diseases and their pathophysiologic mechanisms is described.

Data from numerous epidemiological studies indicate that in many developed countries, heart failure is one of the most common, progressive and predictive of adverse complications of diseases of the cardiovascular system. At the moment, that is a rather acute problem of cardiac rehabilitation of such patients. The purpose of our study was to investigate the effect of various forms of structured learning in special schools for CHF patients on the clinical course and prognosis. Materials and Methods: This study consisted of two phases, including 158 patients with chronic heart failure II–III FC. Evaluated the survival of the knowledge, clinical status, distance of a 6-minute walk, Minnesota QoL questionnaire, adherence to therapy, the frequency of hospital admissions for heart failure decompensation, referral to the clinic, the frequency of deaths, the level of CRP, LV function the results of echocardiography. The results: the use of interactive learning will significantly improve patient compliance to treatment (D=5%), which in turn significantly improved the clinical condition of patients, quality of life, performance test, 6-minute walk, and left ventricular function, as well as reduced the number of hospitalizations with circulatory decompensation (1,6-times), and uptake to the clinic (up to 0,5 times a month). Thus, the use of interactive patient education is an integral part of the cardiorehabilitation events in patients with CHF.

Objective: to study the clinical and economic benefits of adding ivabradine to standard therapy for chronic heart failure (CHF). Subjects and methods. A clinical and economic analysis of the pharmacoeconomic efficacy of ivabradine (Coraxan Servier, France) in patients with CHF was made using the Markov simulation on the basis of the SHIFT trial. The cost-utility ratio (CUR) was calculated by the formula: CUR=DC/Ut, where DC is the direct cost of treatment; Ut is the cost utility expressed in life-years gained (LYG) and quality-adjusted life years (QALY). While calculating the latter, the model used the utility value derived in the SHIFT-PRO trial, by applying the EQ-5D questionnaire. Results. The monthly cost of standard pharmacotherapy was 799,14 rbl. per person. The treatment involving ivabradine cost 1807,77 rbl. The mean total direct cost for treating one patient was 64 741,09 and 47 647,83 rbl. in the ivabradine and placebo groups, respectively. The costs of hospital stay were ascertained to constitute 60% of all the direct costs in patients receiving standard therapy. On the contrary, addition of ivabradine to standard therapy allows avoidance of 309 admissions for worsening CHF, which permitted 23 709 879 rbl. to be saved. Reducing the costs of hospitalization enables one to spend 67% of the means for pharmacotherapy. Following a 10-year simulation period, the standard therapy remains more inexpensive than therapy involving ivabradine (74 585,31 rbl. per person versus 120 843,30 rbl per person) and ensures the lower cost of one LYG and one QALY. At the same time, the therapy added by ivabradine can prevent 1300 admissions for CHF and about 500 deaths per 10,000 patients over 10 years. This will lead to more life-years gained (4,277 LYGs on ivabradine therapy versus 4,083 LYGs on standard therapy), including quality-adjusted life years (3,031 QALYs on ivabradine therapy versus 2,839 QALYs on standard therapy). When ivabradine was added to standard therapy, the cost of one LYG was 238 443 rbl. and that of QALY was 240 927 rbl. Thus, the estimated medical intervention is a cost-effective investment. Conclusions: 1. To enhance the efficiency of CHF treatment with ivabradine causes a rational change in the cost structure. 2. To reduce the costs of hospitalizations and to change the cost structure provide a possibility of increasing those of qualitative therapy. 3. To incorporate ivabradine in therapy for systolic CHF can gain more additional life years, including quality-adjusted life years. 4. To increase expenses on therapy involving ivabradine per LYG is a cost-effective investment.
