Actuality. High risk of hospitalisation and death in patients with heart failure highlight the importance of developing methods to moni‑ tor weight, diuresis, heart rate and other parameters and provide the physicians with an ability to change the therapy immediately if needed. The aim of this work is an analysis of clinical trials which investigate telemonitoring in patients with heart failure. Discussion. The Cochrane meta-analysis is also discussed in this work. Main conclusions. Our analysis showed that there is no consistency among trials. Not all trials have demonstrated that telemonitoring can reduce the risk of death and heart failure hospitalisations. Potentials explanations are lack of compliance with systems which didn’t include the direct contact between the patient and the caregivers, using parameters with low sensitivity in some of the methods and including of stable patients in some of the studies. It is also seeming that effect of telemonitoring is low in regions with existing programs to treat heart failure.
Left ventricular hypertrophy – is one of the most frequent structural changes in the heart. This article is devoted to the assessment of modern views on the causes of myocardial hypertrophy of the donor heart, indications and contraindications for the heart trans‑ plantation, the outlook of expanding the pool of effective donors through the use of these hearts. Here are considered the issues of post-transplantation remodeling of the donor heart myocardium, The pathogenesis features, the nascence risk and possibilities of drug regulation of the transplanted heart‘s myocardial hypertrophy of the left ventricle.

Background. This study examined clinical, demographic, anthropometric, and inheritance factors that influence individual sensitivity to warfarin therapy after heart valve surgery. The clinical significance of the pharmacogenetic approach was assessed using the individual time frame and time spent in the INR therapeutic range. Aims. We determined the clinical outcome of the pharmacogenetic approach at the start of warfarin therapy in patients with prosthetic heart valves. Materials and methods. The study included 915 patients, of which 512 women and 403 men (mean age 56±10 years), living in Western Siberia. Rheumatic heart disease was the main diagnosis that caused the acquired defect. Mechanical prostheses were used in 70% of cases of cardiac surgery. Real-time polymerase chain reaction used for molecular genetic testing. Results. The frequencies of the alleles and genotypes of CYP2C9 and VKORC1 in the study population of patients with heart valves prosthetic correspond to the distribution in Caucasoid populations. The use of pharmacogenetic testing results at the beginning of warfarin therapy reduced the time required for selecting a therapeutic dose of anticoagulant by 2 times and increased the duration of stay in the INR therapeutic range by 20.2%. Conclusion. The use of the pharmacogenetic approach at the begin‑ ning of warfarin therapy contributes to the effectiveness and safety of anticoagulant therapy in this category of patients.
Objective. To study medical awareness of cardiovascular risk factors (RFs) in different types of hospitalized patients (pts). Methods. A total of 150 pts from neurological, endocrinological and cardiac units one of Moscow city hospital were enrolled into the survey (50 pts in each unit). The pts were interviewed during the I-II days of the hospitalization. A special questionnaire was developed in‑ cluding socio-demographic and clinical indicators, open questions on the awareness of traditional cardiovascular RFs and their target values. Results. Pts of three units did not differ in gender and age. The range of diagnoses corresponded to the profile of the unit. The survey revealed an extremely low awareness of major cardiovascular RFs of pts in all 3 units: almost none of them pointed to elevated cholesterol (0%, 4% and 0%, respectively) and blood pressure (2%, 2% and 0%) respectively) as RF of cardiovascular diseases. The pts of the three units most often referred to stress (64%, 56% and 66%, respectively) and unhealthy diet (50%, 56% and 64%, respectively) as the main cardiovascular RFs. On average, pts in three units correctly indicated only 2 RFs. Conclusion. The survey revealed a low awareness of cardiovascular RFs in different types of medical pts, including cardiac pts, at time of hospital admission.
Aim. The study assesses the effects of therapy based on the use of telmisartan in patients with arterial hypertension and stable angina on the clinical and functional indicators of the cardiovascularvascular system. Material and methods. 52 patients with a combination of arterial hypertension (AH) I and II stages and coronary artery disease II with the mean age 63.5 ± 5.4 years (79% males and 21% of females) were enrolled in the trial. The duration of AH and CAD were 17.5±3.8 and 12.5±3.1 accordingly. All patients took a daily 80 mg dose of telmisartan. The efficacy of treatment was estimated in 3,6 and 12 months. Results. The use of telmisartan in complex treatment of high-risk patients with AH has led to decreasing blood pressure to the target level, increasing exercise tolerance (walking the distance from 315.5 m to 410.2 m in 6 minutes). 12 months of therapy based on telmisartan showed significant decrease in left hy‑ pertrophy ventricle (LV myocardial mass index on average by 10.4%), a decrease in the total duration of depression ST segment from 9.6±2.9 to 2.7±1.5 mm and a decrease in the depth of depression from 1.5±0.3 mm to 0.3±0.09 mm, with a trend towards decrease in the number of episodes of ST-segment depression, as well as the absence of a significant change in heart rate. After 12 months of en‑ dothelium-dependent vasodilation therapy, the condition of 31 (60%) patients improved, and 18 (35%) patients showed the tendency to improvement. The tests with reactive hyperemia conducted after 12 months of treatment revealed decreased linear velocity of blood flow in the brachial artery on average by 17%. Conclusion. The use of telmisartan in complex therapy improves the quality of life according to the EQ-VAS questionnaire by 25 points after 12 months of therapy, contributes to lowering blood pressure in 96% of patients, reduc‑ ing myocardial hypertrophy, endothelial dysfunction and severity of ischemic manifestations (reducing the need for nitroglycerin intake to an average of 0,5 inhalations, as well as a decrease in the ST segment depression of 40% after 12 months of therapy).
