Valvular heart disease remains one of the causes of cardiovascular morbidity and mortality worldwide. Aortic stenosis is the most common valvular pathology requiring cardiac surgery. For elderly and senile patients with high risks of volumetric cardiac surgery, a new type of biological prosthesis, a transcatheter implantable aortic valve, has become a solution to the problem. Over the past decade catheter interventions for severe valvular heart disease have evolved from balloon dilatation of native stenotic valves to replacement and reconstructive intervention of diseased valves. Transcatheter aortic valve implantation, which is widespread in the USA and Europe, has also begun to be performed in our country, primarily in comorbid groups of patients. Rapid technological advances in device design are likely to improve immediate and long-term outcomes of surgery and expand the current indications for transcatheter aortic valve implantation. The article analyzes the indications for the procedure in accordance with the latest recommendations of 2021, possible complications of the transcatheter aortic valve implantation, as well as the principles of patient management after the procedure, including the principles of drug therapy in this group of patients. Separately, the topic of aortic regurgitation and the possibility of transcatheter aortic valve implantation are touched upon, since this pathology is a new indication that has appeared only in the latest recommendations of the European Society of Cardiology. In this review, we want to acquaint physicians with the indications for transcatheter aortic valve implantation, the main complications, and the principles of managing patients in the perioperative period. The complication rate after transcatheter aortic valve implantation is decreasing due to technical advances and experience of interventional surgeons. In-depth knowledge of potential complications and their prevention plays a key role in improving the immediate and long-term results of surgery.

Atrial fibrillation and ischemic heart disease are the key problems in cardiology. Despite of numerous clinical trials and researches underlying molecular biology remains uncertain. Atrial fibrillation and ischemic heart disease are often combined. During ischemic heart disease progression myocardial tissue structure are changing which lead to structural and electrophysiological remodeling and promote atrial fibrillation. It has been shown a crucial role of oxidative stress and chronic systemic inflammation in ischemic heart disease and atrial fibrillation. Myeloperoxidase (MPO) is one of marker of oxidative stress and inflammation that located in azurophilic granules of neutrophils and monocytes. There are a numerous articles showed a relation between MPO level and cardiovascular disease. MPO is a peroxidase enzyme that is important part of immune system. During disease MPO could facilitate chronic inflammation and local tissue damage through active oxygen forms. MPO releases after lysosome conjunction with phagosome. Oxygen reductase activity of MPO lead synthesis of hypochlorous acid that play role not only in organism protection from infection agents but in matrix transformation and fibrosis. It has been shown MPO can destabilize atherosclerotic plaque and modifies low- and high-density lipoproteins that promote atherosclerosis and ischemic heart diseaseу progression. This review summarizes current data about role of MPO in atrial fibrillation and ischemic heart disease pathogenesis.

A review of data on the possible causes of an increase rheumatoid factor (RF), antibodies against cyclic citrullinated peptide (ACCP) and antibodies to modified citrullinated vimentin (AMCV) in patients without rheumatoid arthritis (RA) is presented. The possibility of hyperproduction of these autoantibodies before the development of the clinical picture of RA was indicated. It is indicated that ACCP and IgA RF have the greatest prognostic value in terms of the subsequent development of RA. These antibodies are recommended to be additionally determined in diagnostically difficult cases. Data on the sensitivity and specificity of detection of RF, ACCP and AMCV in the diagnosis of RA are summarized. The results of detection of the discussed antibodies in various rheumatic (other than RA) and non-rheumatic diseases are presented in detail. Particular attention is paid to diseases in which increased synthesis of RF, ACCP and AMCV may not be accompanied by clear clinical symptoms (Sjögren’s disease, autoimmune thyroiditis, some chronic infections, silicosis, monoclonal gammopathy, etc.). Recommendations are given for examining patients with “accidentally” identified increase in RF or ACCP.

Research objective: Quantitative estimation of social-demographic and social-economic impact of the switch of traditional cigarettes smoking to modified risk tobacco products consumption, based on effect upon smoking-related mortality and diseases rates.

Methods. Target group – consumers of smoking tobacco: conventional cigarettes (CC) and modified risk tobacco products (MRTP). Base of calculations – analysis of available time series for: CC and MRTP consumption, life expectancy and healthy life expectancy coefficients, statistics on smoking-related mortality and diseases rates, including data on key nosologies (malignant neoplasms of respiratory system, digestive organs, urinary tract; chronic obstructive pulmonary disease; circulatory diseases; cerebrovascular diseases.

Results. We implemented prognoses for all the above mentioned parameters to year 2035, calculated direct medical and indirect costs for demographic and economic loss with attention to budget impact analysis, developed five scenarios based on different CC and MRTP consumption.

The model of switching from CC to MRTP consumption proves a significant decline of demographic and economic burden even with rather modest MRTP replacement for CC. With current practices of switching from CC to MRTP remaining, during 2021–2035 summary impact would result in 3.6 mln of years saved, 7.7 mln of healthy years saved, 120 thous. of mortal cases and 345 thous. diseases cases prevented. The economic burden would be 3.3 trillion rubles lower.

Conclusion. Smoking cessation is the optimal method to reduce health risks, and state policy for stimulation of smoking quitting is necessary. Along with that, transition from CC to MRTP may be an alternative way to reduce health risks for those smokers with long smoking history and either psychological or physiological causes who cannot quit smoking.

Even small in the terms of percent transition from CC to MRTP may result in significant decrease of demographic and economic burden on the national scale.

Back pain (BP) is a major public health problem worldwide with high prevalence and disability. In most cases are associated with degenerative spinal disease (degenerative disc disease, DDD), myofascial syndrome, facet joint syndrome, spinal spondylosis, scoliotic deformation, sacroilial joint dysfunction, lumbar stenosis and other causes. The article describes the basics of the doctor’s approach to the diagnosis of back pain, describes the main strategies of patients routing. The algorithm proposed here includes detection of dangerous conditions, verification of inflammatory rhythm of BP according to criteria ASAS 2009, revealing of persistent phenotype of the lower back pain, stratifying patients for the risk of chronic lower back pain StarT Back in mechanical rhythm; multidisciplinary approach with inclusion of the rheumatologist in specialists team, and after initial consultation the therapist gives direction to the rheumatologist, if necessary. A therapist who treats a patient with persistent BS and a high risk of chronization without symptoms of “red flags” should prescribe an magnetic resonance imaging of the spine. The detection of total lesion of the vertebral motor segments in the case of severe back pain is the basis for the diagnosis of spinal osteoarthritis and subsequent prescription of non-medicamentous and pharmacological therapy, including SYSADOA, in particular Alflutop. The developed algorithm allows to quickly diagnose spinal osteoarthritis at a young age and to suspect axial spondylitis. Presented triad of MR-traits associated with persistent phenotype pain, which will help the therapist to establish the diagnosis of spinal osteoarthritis. The algorithm clearly describes the routing of patients to related specialists (rheumatologist, neurologist, etc.) according to the identified data.

Hyperuricemia is most often combined with lipid metabolism disorders, modifiable risk factors for coronary heart disease, stroke, abdominal obesity, type 2 diabetes mellitus, arterial hypertension, urolithiasis, chronic kidney disease. Current data indicate the presence of pro-inflammatory, pro-oxidant and vasoconstrictive effects of uric acid, which may contribute to the development of cardiometabolic disorders. Normal serum uric acid levels are <6 mg / dl (<360 mmol / l) for women and <7 mg / dl (<420 mmol / l) for men. Currently, the role of hyperuricemia as an independent biomarker of the risk of cardiovascular events is emphasized. Both gout and subclinical hyperuricemia are associated with unfavorable cardiovascular outcomes. Patients should be informed about the risk factors of hyperuricemia; the need for lifestyle modification, diet compliance, and correction of drug therapy for comorbid conditions. According to international and domestic recommendations, urate-lowering therapy is indicated for asymptomatic hyperuricemia (>360 mmol / l) and high cardiovascular risk. The data available today allow us to consider the target serum uric acid level <5 mg / dl (<300 mmol / l) for patients with high cardiovascular risk, including at least 2 of the following risk factors: hypertension, diabetes mellitus, dyslipidemia, stroke, heart attack, chronic disease kidneys, and <6 mg / dl for patients who do not have these risk factors. The urate-lowering drug is selected taking into account the concomitant pathology and the presence or absence of liver or kidney dysfunction. Xanthine oxidase inhibitors are still the first-line drugs for the correction of hyperuricemia. The superiority of xanthine oxidase inhibitors is due to the potential inhibition of the production of reactive oxygen species and their antioxidant effect. Treatment of gout is aimed at achieving clinical improvement in acute and chronic arthritis, preventing recurrence of arthritis and damage to internal organs, as well as reducing the risks of negative effects on comorbid pathology. Clinicians are faced with the task of controlling cardiovascular diseases in patients with asymptomatic hyperuricemia and gout. Further studies are needed to investigate the relationship between gout, hyperuricemia and increased risk of cardiovascular diseases, as well as to establish a more complete picture of the prevalence of a wide range of comorbid conditions.
