Aim To study the etiology and the dynamics of prevalence and mortality of CHF; to evaluate the treatment coverage of such patients in a representative sample of the European part of the Russian Federation for a 20-year period. Material and methods A representative sample of the European part of the Russian Federation followed up for 2002 through 2017 (n=19 276); a representative sample of the population of the Nizhny Novgorod region examined in 1998 (n=1922).Results During the observation period since 2002, the incidence of major CHF symptoms (tachycardia, edema, shortness of breath, weakness) tended to decrease while the prevalence of cardiovascular diseases has statistically significantly increased. During the period from 1998 through 2017, the prevalence of I-IV functional class (FC) CHF increased from 6.1 % to 8.2 % whereas III-IV FC CHF increased from 1.8 % to 3.1 %. The main causes for the development of CHF remained arterial hypertension and ischemic heart disease; the role of myocardial infarction and diabetes mellitus as causes for CHF was noted. For the analyzed period, the number of treatment components and the coverage of basic therapy for patients with CHF increased, which probably accounts for a slower increase in the disease prevalence by 2007–2017. The prognosis of patients was unfavorable: in I-II FC CHF, the median survival was 8.4 (95 % CI: 7.8–9.1) years and in III-IV FC CHF, the median survival was 3.8 (95 % CI: 3.4–4.2) years.

Aim. To evaluate clinical-economical effectiveness of direct oral anticoagulants (DOAC) dabigatran, rivaroxaban, and apixaban in comparison with warfarin in atrial fibrillation (AF) therapy. Materials and Methods. Mathematical modeling (tree derivation of solutions) on a temporary 5-year horizon from the medical healthcare system perspective. Methods of clinical-economic analysis: analysis “cost-effectiveness”, “budget impact”, and “the analysis of unseized opportunities”. Results. Total direct costs (DC) were lower by 10.3% when dabigatran was used, by 5.2%, when rivaroxaban was used, and by 10.9%, when apixaban was used in comparison with warfarin. The most significant difference was observed due to different cost of therapy for bleeding complications (in the structure of the costs, it occupied 30-38%). In the group of dabigatran, DC on bleeding complications were lower than in the group of warfarin by 22.0%, in the group of rivaroxaban – by 10.9%, in the group of apixaban – by 36.8%. Besides, in the group of dabigatran, the costs associated with the treatment for ischemic stroke were lower by 28.1% The strategy of the application of DOAC in comparison with warfarin provided more adjusted life years (ALY), complications adjusted life years (CALY), and its lower cost. The application of DOAC saves significant funds. At the same time, the saved funds will provide the purchase of additional modern drugs for patients. The cost-cutting reaches 12% for 5 years and up to 33 patients out of 1000 can receive additional treatment. Conclusion . Due to the prevention of thromboembolic complications in patients that received direct oral anticoagulants, the direct costs can be reduced by 28.1% and due to the prevention of bleeding complications – by 36.8% in comparison with the application of warfarin. Direct oral anticoagulants provide more adjusted life years and complications adjusted life years at a lower cost.

This article discusses relevant aspects in the treatment of patients with COVID-19. Up-to-date information about principles for administration of statins, antithrombotics, and antiarrhythmics is presented. The authors addressed in detail specific features of reversing heart rhythm disorders in patients with coronavirus infection and the interaction of antiarrhythmic and antiviral drugs. Recommendations are provided for outpatient and inpatient antithrombotic therapy for patients with COVID-19. Issues of antithrombotic and antiviral drug interaction are discussed.

Objective: to analyze whether comorbidity affects the cost of treatment and medical services in elderly patients with atrial fibrillation (AF). Materials and methods. We conducted a retrospective analysis of 98 patients with AF. Comorbidity was evaluated using the CIRS-G scale (Cumulative Illness Rating Scale for Geriatrics) and the Charlson criterion. The “cost of illness” calculations included direct costs only. Results. In elderly patients with AF (mean age 74.7±8.8 years), high rate of comorbidity was typically found. Charlson comorbidity index amounted to 4.0±1.8, and the CIRS-G score – to 8.0±2.8. AF is often associated with heart diseases such as hypertension – 98.9%, coronary heart disease – 27.6%, and congestive heart failure – 76.5%. A patient with AF received on average 7.5±3.8 medications. Direct costs amounted to 18298.2±9440.4 RUB per patient with AF per year. Of this amount, 78.8% were spent for outpatient treatment, 16.5% for hospitalization and 4.7% for ambulance service. Cardiac medications comprised 66.4% of the total direct costs. In patients with high comorbidity, there are high costs of treatment of concomitant diseases, high secondary costs as well as costs for a doctor visit. Conclusion. An average elderly patient with AF receives 7.5±3.8 permanent medications, which correlates with the severity of comorbidity by the Charlson index (r=0.59; p=0.000) and the CIRS-G score (r=0.29; p=0.004). Management of such patients at the outpatient clinic is by large (66.4%) associated with direct costs of the prescribed medications. However, patients with high comorbidity still need more vital drugs, as the cost of treatment of concomitant diseases increases. Notably, these patients spend 4 times more funds for drugs without proven efficacy.

Aim To study the effect of regular drug therapy for cardiovascular and other diseases preceding the COVID-19 infection on severity and outcome of COVID-19 based on data of the ACTIVE (Analysis of dynamics of Comorbidities in paTIents who surVived SARS-CoV-2 infEction) registry.Material and methods The ACTIVE registry was created at the initiative of the Eurasian Association of Therapists. The registry includes 5 808 male and female patients diagnosed with COVID-19 treated in a hospital or at home with a due protection of patients’ privacy (data of nasal and throat smears; antibody titer; typical CT imaging features). The register territory included 7 countries: the Russian Federation, the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Kyrgyz Republic, the Republic of Moldova, and the Republic of Uzbekistan. The registry design: a closed, multicenter registry with two nonoverlapping arms (outpatient arm and in-patient arm). The registry scheduled 6 visits, 3 in-person visits during the acute period and 3 virtual visits (telephone calls) at 3, 6, and 12 mos. Patient enrollment started on June 29, 2020 and was completed on October 29, 2020. The registry completion is scheduled for October 29, 2022. The registry ID: ClinicalTrials.gov: NCT04492384. In this fragment of the study of registry data, the work group analyzed the effect of therapy for comorbidities at baseline on severity and outcomes of the novel coronavirus infection. The study population included only the patients who took their medicines on a regular basis while the comparison population consisted of noncompliant patients (irregular drug intake or not taking drugs at all despite indications for the treatment).ResultsThe analysis of the ACTIVE registry database included 5808 patients. The vast majority of patients with COVID-19 had comorbidities with prevalence of cardiovascular diseases. Medicines used for the treatment of COVID-19 comorbidities influenced the course of the infectious disease in different ways. A lower risk of fatal outcome was associated with the statin treatment in patients with ischemic heart disease (IHD); with angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor antagonists and with beta-blockers in patients with IHD, arterial hypertension, chronic heart failure (CHF), and atrial fibrillation; with oral anticoagulants (OAC), primarily direct OAC, clopidogrel/prasugrel/ticagrelor in patients with IHD; with oral antihyperglycemic therapy in patients with type 2 diabetes mellitus (DM); and with long-acting insulins in patients with type 1 DM. A higher risk of fatal outcome was associated with the spironolactone treatment in patients with CHF and with inhaled corticosteroids (iCS) in patients with chronic obstructive pulmonary disease (COPD).Conclusion In the epoch of COVID-19 pandemic, a lower risk of severe course of the coronavirus infection was observed for patients with chronic noninfectious comorbidities highly compliant with the base treatment of the comorbidity.

The organizer of the registers “Dynamics analysis of comorbidities in SARSCoV-2 survivors” (AKTIV) and “Analysis of hospitalizations of comorbid patients infected during the second wave of SARS-CoV-2 outbreak” (AKTIV 2) is the Eurasian Association of Therapists (EAT). Currently, there are no clinical registries in the Eurasian region designed to collect and analyze information on long-term outcomes of COVID-19 survivors with comorbid conditions. The aim of the register is to assess the impact of a novel coronavirus infection on long-term course of chronic non-communicable diseases 3, 6, 12 months after recovery, as well as to obtain information on the effect of comorbidity on the severity of COVID-19. Analysis of hospitalized patients of a possible second wave is planned for register “AKTIV 2”. To achieve this goal, the register will include men and women over 18 years of age diagnosed with COVID-19 who are treated in a hospital or in outpatient basis. The register includes 25 centers in 5 federal districts of the Russian Federation, centers in the Republic of Armenia, the Republic of Kazakhstan, the Republic of Kyrgyzstan, the Republic of Belarus, the Republic of Moldova, and the Republic of Uzbekistan. The estimated capacity of the register is 5400 patients.

Purpose To evaluate the clinical and economic effectiveness of direct oral anticoagulants (DOAC) - dabigatran/D, rivaroxaban/R, apixaban/A compared with warfarin/W in the treatment of atrial fibrillation (AF). Methods The mathematical model (MM) was used (decision-tree building- DTB) to assess the clinical and economic effectiveness of the DOAC use in comparison with W in the AF treatment. MM was based on the results of basic clinical trials on the use of D (RE-LY); R (ROCKET) and A (ARISTOTLE). MM was carried out on a time horizon of 5 years from the perspective of the healthcare system (HS). The method of cost-effectiveness analysis CER. CER = DC/Ef, CER is the cost-effectiveness balance of the alternative, DC is direct costs, Ef is the number of adjusted life years (ALY) and adjusted life years without complications (ALYC). Budget Impact Analysis. BIA = S (1) − S (2), BIA is the result of the analysis of “impact on the budget”, in monetary terms; S (l) – the total economic effect of the use of one drug, in monetary terms; S (2) – the total economic effect of the use of another drug, in monetary terms. Analysis of “lose opportunities”. MOA = ΔS/Costmin, MOA is the result of the analysis of “lose opportunities”, ΔS is the difference in the total economic effects of the two compared drugs, Costmin is the cost of using the lowest cost drugs. Results The MM showed that as a result of pair-wise comparison the DOAC and W, the greatest DC were in group of treatment with the W. The total costs when using D were 10.3% less and amounted to 4129711 against 4605164 rub. per 100 patients. The cost of using R is 5.2% less (4887744 against 5156589); using A by 10.9% (3946528 against 4433820). The greatest difference was due to the different costs of adverse drug reaction treatment (30–38% in the cost structure). In the D group, this cost component was less than the W -by 22.0%, in the R – by 10.9%, in the A – by 36.8%. Costs associated with ischemic stroke treatment were less then 28.1% in the D group. The strategy of using DOAK compared with W allows to provide a greater number of ALY and ALYC – 4, 34 and 4.3 when comparing D and W, 4.3 and 4.25 when R and W; and 4.25 and 4.2 – A and W. ALYC respectively – 3.92 and 3.79; 3.51 and 3.6; 3.9 and 3.74. The cost of ALY is 9516.65 against 10706.45 rub; 11,374.34/12123.81; 9,295.19/10547.31. The cost of ALYC respectively: 10,534.98 against 12150.83 rub.; 13,925.20/14733.11 and 10119.3/11855.13. The use of DOAK allows to save significant public funds, and the savings saved allow to treat the patients in addition by modern drugs. Savings up to 12% in 5 years, while up to 33 patients out of 1000 can be treated additionally. Conclusion DC resulting from the prevention of thromboembolic complications when using DOAC in comparison with W can be reduced by 28.1%, hemorrhagic complications by 36.8%. DOAC can save a greater number of ALY and ALYC at a lower cost. Funding Acknowledgement Type of funding source: None

Aim.To perform a repeated epidemiological study of a representative sample in the European part of the Russian Federation in 2017 and to compare the dynamics of arterial hypertension (AH) prevalence with the effectiveness of blood pressure (BP) control in the population compared to 1998, 2002, and 2007.Materials and methods.A representative sample of the European part of the Russian Federation was created in 2002 and re-examined in 2007 and 2017. In 1998, a pilot project was performed for examining a representative sample for the Nizhniy Novgorod region.Results.During 19 years of follow-up, the AH prevalence increased from 35.5 to 43.3%. Te awareness and treatment coverage reached 76.9 and 79.3%, respectively, in 2017. Achievement of the target BP with a single measurement also increased among patients receiving antihypertensive medication from 14.3 to 34.9%. For the treatment of AH, medium-acting antihypertensive drugs are used, ofen at suboptimal doses.Conclusion.Epidemiological indices of awareness, treatment coverage, and number of effectively managed patients with AH have improved. However, the AH prevalence has increased by 7.8% for 19 years, which indicates inefciency of the primary prevention of this disease.

The article discusses pathogenesis and treatment of COVID-19. The authors presented state-of-the-art insight into hemostatic disorders in patients with COVID-19 and clinical recommendations on prevention of thrombosis and thromboembolism in patients infected with SARS-CoV-2. The article discussed in detail a new hypothesis proposed by Chinese physicians about a new component in the pathogenesis of COVID-19, namely, about the effect of SARS-CoV-2 virus on the hemoglobin beta-chain and the formation of a complex with porphyrin, which results in displacement of the iron ion. Thus, hemoglobin loses the capability for transporting oxygen, which aggravates hypoxia and worsens the prognosis. The article stated rules of hemotransfusion safety in the conditions of COVID-19 pandemic.

Aim.To study the clinical course specifics of coronavirus disease 2019 (COVID-19) and comorbid conditions in COVID-19 survivors 3, 6, 12 months after recovery in the Eurasian region according to the AKTIV register.Material and methods.The AKTIV register was created at the initiative of the Eurasian Association of Therapists. The AKTIV register is divided into 2 parts: AKTIV 1 and AKTIV 2. The AKTIV 1 register currently includes 6300 patients, while in AKTIV 2 — 2770. Patients diagnosed with COVID-19 receiving in- and outpatient treatment have been anonymously included on the registry. The following 7 countries participated in the register: Russian Federation, Republic of Armenia, Republic of Belarus, Republic of Kazakhstan, Kyrgyz Republic, Republic of Moldova, Republic of Uzbekistan. This closed multicenter register with two nonoverlapping branches (in- and outpatient branch) provides 6 visits: 3 in-person visits during the acute period and 3 telephone calls after 3, 6, 12 months. Subject recruitment lasted from June 29, 2020 to October 29, 2020. Register will end on October 29, 2022. A total of 9 fragmentary analyzes of the registry data are planned. This fragment of the study presents the results of the post-hospitalization period in COVID-19 survivors after 3 and 6 months.Results.According to the AKTIV register, patients after COVID-19 are characterized by long-term persistent symptoms and frequent seeking for unscheduled medical care, including rehospitalizations. The most common causes of unplanned medical care are uncontrolled hypertension (HTN) and chronic coronary artery disease (CAD) and/or decompensated type 2 diabetes (T2D). During 3- and 6-month follow-up after hospitalization, 5,6% and 6,4% of patients were diagnosed with other diseases, which were more often presented by HTN, T2D, and CAD. The mortality rate of patients in the post-hospitalization period was 1,9% in the first 3 months and 0,2% for 4-6 months. The highest mortality rate was observed in the first 3 months in the group of patients with class II-IV heart failure, as well as in patients with cardiovascular diseases and cancer. In the pattern of death causes in the post-hospitalization period, following cardiovascular causes prevailed (31,8%): acute coronary syndrome, stroke, acute heart failure.Conclusion.According to the AKTIV register, the health status of patients after COVID-19 in a serious challenge for healthcare system, which requires planning adequate health system capacity to provide care to patients with COVID-19 in both acute and post-hospitalization period.

The international AKTIV register presents a detailed description of out- and inpatients with COVID-19 in the Eurasian region. It was found that hospitalized patients had more comorbidities. In addition, these patients were older and there were more men than among outpatients. Among the traditional risk factors, obesity and hypertension had a significant negative effect on prognosis, which was more significant for patients 60 years of age and older. Among comorbidities, CVDs had the maximum negative effect on prognosis, and this effect was more significant for patients 60 years of age and older. Among other comorbidities, type 2 and 1 diabetes, chronic kidney disease, chronic obstructive pulmonary disease, cancer and anemia had a negative impact on the prognosis. This effect was also more significant (with the exception of type 1 diabetes) for patients 60 years and older. The death risk in patients with COVID-19 depended on the severity and type of multimorbidity. Clusters of diseases typical for deceased patients were identified and their impact on prognosis was determined. The most unfavorable was a cluster of 4 diseases, including hypertension, coronary artery disease, heart failure, and diabetes mellitus. The data obtained should be taken into account when planning measures for prevention (vaccination priority groups), treatment and rehabilitation of COVID-19 survivors.

COVID-19 is a severe infection with high mortality. The concept of the disease has been shaped to a greater extent on the basis of large registers from the USA, Spain, Italy, and China. However, there is no information on the disease characteristics in Caucasian patients.Therefore, we created an international register with the estimated capacity of 5,000 patients — Dynamics Analysis of Comorbidities in SARS-CoV-2 Survivors (AKTIV SARS-CoV-2), which brought together professionals from the Russian Federation, Republic of Armenia, Republic of Kazakhstan, and Kyrgyz Republic. The article presents the first analysis of the register involving 1,003 patients. It was shown that the most significant difference of the Caucasian population was the higher effect of multimorbidity on the mortality risk vs other registers. More pronounced effect on mortality of such diseases as diabetes, obesity, hypertension, chronic kidney disease, and age over 60 years was also revealed.

Aim. To perform the comparative cost-efficacy analysis of various antihypertensive therapies in hypertensives patients.Material and methods. 140 hypertensive patients with history of ineffective antihypertensive therapy were randomized in to 4 groups, 35 patients in each one. Patients of Group A received indapamide retard plus perindopril; group B - indapamide retard plus amlodipine; group C - amlodipine plus lisinopril; group D - amlodipine plus bisoprolol. The Russian version of general questionnaire MOS-SF-36 was applied for quality of a life estimated. Endothelium function was evaluated with B-mode ultrasonography (Acuson 128 ХР/10). Albuminuria level was detected by immunoturbometric method (Integra-700, Roche).Results. The drug combination B had the least cost. The drug combination C was the most effective. The drug combination C was the most economically rational. The drug combination A was the least economically rational for BP reduction. However the drug combination A was comparable with drug combination C in effects on quality of life and on endothelium function, and it was the most economically rational for albuminuria reduction.Conclusion. Indapamide retard plus perindopril combination is the most economically rational in patients with target-organ lesions (nephropathy). Lisinopril plus amlodipine combination is economically rational in patients without target-organ lesions.

Objective. To determine the priority used to vital drugs in сhronic obstructive pulmonary disease (COPD) patients in hospitals of the Kirov region. Materials and Methods. We analyzed 143 medical records of the patient, the analysis of cost of illness, ABC\ VEN — analysis. Results. The results of АВС analysis show that the percentage correlation of medicines of different groups generally corresponds to the recommended norm. The results of VEN analysis prove that the number of vital drugs is decreased while the number of second line drugs is increased. Conclusion. Most of the financial costs were for the treatment of exacerbations of COPD, the appropriate Federal clinical guidelines, simultaneously, there is an active assignment of the second line drugs. Reducing their use and rational therapy of acute conditions will enable competently reallocate financial resources in favour of vital drugs to increase the effectiveness of treatment and reduce the cost of inpatient care.

Aim. To carry out a comparative pharmacoeconomic analysis of two different types of antihypertensive therapy in patients with arterial hypertension (HT). Material and methods. 38 patients with essential HT (aged 18 to 70 years, 11 males and 27 females) associated with metabolic syndrome, and having a history of previous ineffective antihypertensive therapy were included into the study. The patients were randomized into 2 groups. Patients of V/A group received a fixed combination of valsartan and amlodipine (Exforge, Novartis) in dose of 5/160 and 10/160 mg depending on blood pressure (BP) level. Patients of L/A group received losartan (Lorista, KRKA) in dose of 100 mg and amlodipine (Tenox, KRKA) in dose of 5 and 10 mg. Treatment duration was 24 weeks. If target level of BP was not achieved during 12 weeks, indapamide retard was added to the therapies (Ravel SR, KRKA). Dinamics of BP and left ventricular mass index (LVMI) were considered. Cost-effectiveness method of analysis was used. Results. In V/A group 75% of patients achieved target BP levels for 24 weeks, while in L/A group — 33.3% of patients, and 16.7% of patients more after indapamide addition. L/A therapy cost was lower in comparison with this of V/A therapy: 57864.24 vs 156671.0 rubles per 24 weeks, respectively. Calculation shows that additional cost of 669.23 rubles during 24 weeks is needed to achieve BP target level in every next patient when V/A therapy is used instead of L/A therapy. LVMI reduction by 1% took 1015.13 rubles cost in V/A group and almost 6 times more in L/A group. Conclusion. Pharmacoeconomic analysis revealed that generic combination of L/A is the most cost-effective for BP reduction. Very low cost is required to achieve additional effect with original fixed V/A combination. V/A combination is the most economical for the left ventricular hypertrophy reduction. Thus, V/A combination is rational for use in HT patients with severe target-organs damage.

Atrial fibrillation is a serious social and health problems, the most common arrhythmia in practice, leading to an increased risk of death, stroke, heart failure. The results of pharmacoeconomical studies allow to evaluate the quality of drug therapy for atrial fibrillation, find rational drug usage and identify ways to optimize the consumption of medications. The objective of investigation is to hold ABC-, VENand frequency analysis of atrial fibrillation in out-patients to assess their compliance with national and international recommendations. Materials and methods. To analyze the treatment of atrial fibrillation 98 outpatients with atrial fibrillation were randomly selected. Every patient appealed to the reception to the physician at least twice in 2013. The data was recorded in a special card, and then analyzed using ABC-, VENand frequency analysis. Results. For the treatment of patients with different forms of atrial fibrillation has been used 114 types of drugs to the INN. Patients received from 3 to 12 drugs. For the treatment of patient with atrial fibrillation it spends an average of 11245.2 rubles per patient, for the treatment of heart disease it spends 8379.51 rubles., that is about 74.5%. The study found that received data is satisfied modern recommendations. The results of frequency analysis showed that the most prescribed drugs are medications with proven efficacy to the quality and duration of life. Conclusions. Data analysis revealed that the percentage volume of drugs between the groups as a whole corresponds to the recommended distribution of drugs.

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.

Aim. To compare tolerability of various antihypertensive combinations in patients with arterial hypertension (HT).Material and methods. 140 patients with HT with history of non-effective antihypertensive therapy were randomized in 4 groups, 35 patients in each. Patients of group A received indapamide retard/perindopril; group B - indapamide retard/amlodipine; group C – amlodipine/lisinopril; group D – amlodipine/bisoprolol. Therapy duration was 12 weeks.Results. 28 (20%) patients dropped out of the study. All antihypertensive combinations significantly decreased blood pressure level. Patients of group A did not stop therapy because of adverse events. 6 (17,1%) dropped out of the study because of ineffective therapy in maximal doses and therapy rejection. Palpitation was a reason of drug withdrawal in 3 (8,6%) of 8 (22,9%) dropped patients of group B. Low limb edema was a reason of drug withdrawal in 4 (11,4%) of 8 (22,9%) dropped patients of group D. Cough was a reason of drug withdrawal in 4 (11,4%) of 5 dropped patients of group C. Dose reduction was needed in some patients of all groups because of hypotension.Conclusion. The adverse events were observed in 25% of patients during 12 weeks of therapy. The patients received indapamide retard/amlodipine and amlodipine/bisoprolol had the highest rate of drug withdrawal because of adverse events. Low limb edema, cough and palpitation were the most frequent adverse events needed therapy withdrawal.

Aim. To study therapeutic equivalence of rosuvastatin generic and original medication and to conduct the pharmacoeconomic analysis to compare the impact of the drug on direct expenses in secondary prevention for the patients with chronic ischemic heart disease (CHD). Material and methods. The open label, prospective observational study performed with the switch of medication, that included 38 patients with chronic CHD and duration of 6 months. During 3 months the patients received original drug rosuvastatin Crestor 10-20 mg, leading to the target level of low density cholesterol
