Literature search was carried out in the following databases: PubMed, Google Scholar, Web of Science from 1990 to 2023 for all studies with the keywords “myocardial infarction and young age”, “atherosclerosis and young age”, “atherothrombosis and young age”. An analysis of all available clinical recommendations of leading specialized societies in the field of cardiology, hematology, and angiology was also carried out. The presented review is not systematic view of the specifics of the subject, its breadth, as well as the task set – to expand the clinical thinking of the doctor. It is undeniable that primary prevention of myocardial infarction is more effective. Given the annual increase in the number of myocardial infarctions at a young age, it is necessary to create a special tool for risk stratification in young patients, since there is no such tool in the clinical guidelines. Despite the greater contribution of non-atherogenic causes to the development of myocardial infarction in young patients, atherosclerosis is still the main cause of its development. The authors of the review confirm the fact that there is currently no specially developed algorithm for managing patients with myocardial infarction at a young age, based on the identification of a number of traditional and non-traditional risk factors, on enhanced rehabilitation measures. All these positions are currently formulated in the aims and objectives of a special sevenyear study of myocardial infarction in young patients planned at our institute.","PeriodicalId":11859,"journal":{"name":"Eurasian heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140248601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with heart failure have increased hospital readmission rates and mortality around the world. Heart failure often coexists with comorbidities of which cognitive impairment is particularly important. Сognitive impairment is present in around 30% to 80% in heart failure decreases quality of life and increases the frequency of repeated hospitalizations, increases mortality and worsens the prognosis in such patients. Despite existing research, the underlying pathophysiology of the relationship between heart failure and cognitive impairment remains poorly understood. The article discusses the best available evidence concerning different pathophysiological mechanisms behind cognitive impairment in individuals with heart failure. Heart failure and cognitive impairment have a number of common pathophysiological pathways including reduced cerebral blood flow, inflammation, neurohumoral activations, oxidative stress and changes in serum biomarkers or proteins. Understanding the pathophysiology of diseases will allow the effective evaluation of health status and development of suitable treatments. Prompt detection of cognitive impairment will bring about better clinical outcomes in heart failure patients. This review raises questions about the relationship between heart failure and cognitive dysfunction, provides evidence on the impact of new therapeutic options for treating heart failure on cognitive function, and suggests potential future research directions. For example, implantation of an artificial left ventricle may improve cognitive function; however, there are studies on immediate improvement in cognitive function followed by gradual deterioration over time after implantation of an artificial left ventricle, which requires long-term study In addition, evidence is provided for the effectiveness of using a relaxation scenario in virtual reality technology to reduce anxiety and affective complaints in somatic hospitalized patients, but the ability to improve cognitive function in patients with chronic heart failure remains to be explored.","PeriodicalId":11859,"journal":{"name":"Eurasian heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140249861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the vast majority of cases, PVC has a good prognosis, but in some cases it can cause serious, including lifethreatening complications. On the other hand, asymptomatic, frequent PVC can lead to the development of left ventricular (LV) systolic dysfunction, which can be reversible with effective therapy. Medications remain the mainstay of therapy for PVC. However, the effectiveness of some drugs is quite low, while other drugs have significant side and proarrhythmic effects. Technological advances in the field of radiofrequency (RF) catheter ablation in recent years have opened up tremendous prospects in the radical correction of PVC and put forward this approach in selective cases as the method of choice. However, this invasive technology may at the same time carry the risks of serious complications, which can occur in up to 5% of individuals undergoing this procedure. The potential risks of RF catheter ablation largely depend on the accessibility of the ectopic focus. In this regard, differential diagnosis of the source of ectopia is of great importance for a balanced assessment of the possible risks and effectiveness of this invasive method. Standard diagnostic methods, such as 12-lead electrocardiography, Holter monitoring and echocardiography, allow in many cases to make the best decision regarding further management tactics. Frequent, asymptomatic PVC needs in annual monitoring to prevent LV systolic dysfunction development in cases high potential RF catheter ablation risks and drugs ineffectiveness. Traditional echocardiography and novel ultrasound technologies can help in this difficult of choice cases.","PeriodicalId":11859,"journal":{"name":"Eurasian heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140249992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Impaired synthesis and reduced bioavailability of nitric oxide is one of the key pathophysiological mechanisms of the development and progression of the disease. The review paper presents key data from the evidence base on the clinical use of tadalafil, a phosphodiesterase type 5 inhibitor (PDE5), which in August 2023 approved by the Pharmaceutical Committee of the Russian Ministry of Health for the indication – treatment of patients with PAH. Tadacardil from Canonpharma Production is the first and only drug in Russian practice today with the active substance tadalafil with the registered indication “PAH”, approved in the Eurasian Guidelines for the diagnosis and treatment of pulmonary hypertension 2023 and available on the territory of the Russian Federation and the EAEU. Tadacardil is indicated for use in adult patients with PAH functional class II and III according to the WHO classification to increase exercise tolerance. The efficacy of tadalafil has been shown in idiopathic PAH and PAH associated with connective tissue diseases. The recommended dose is 40 mg (2 tablets of 20 mg) once a day. The paper describes the mechanism of action and pharmacological effects of PDE5 inhibitors, features of the pharmacokinetics of tadalafil in comparison with other drugs of the class. The advantages of Tadacardil from Canonpharma Production are the proven effecacy of use in patients with PAH, ease of use due to a single dose of 2 tablets of 20 mg once a day in a standard dose; good tolerability and favorable safety profile; proven bioequivalence to the reference drug. In light of the new Eurasian recommendations for the diagnosis and treatment of PH, tadalafil has a wide field for clinical use, which will improve the treatment options for patients with PAH both in mono- and combination therapy.","PeriodicalId":11859,"journal":{"name":"Eurasian heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140395495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A better understanding of the biology of chromatin (DNA/histone complexes) and non-coding RNAs (ncRNAs) has enabled the development of epigenetic (epi) preparations capable of modulating transcriptional programs associated with cardiovascular disease. This is especially true in heart failure, where epigenetic mechanisms have been shown to underlie the development of several pathological processes such as left ventricular hypertrophy, fibrosis, cardiomyocyte apoptosis, and microvascular dysfunction. Targeting epigenetic signals may represent a promising approach, especially in patients with heart failure with preserved ejection fraction (HFpEF), where the prognosis remains poor and effective treatments are not yet available. Under these conditions, epigenetics can be used to develop individualized therapeutic approaches, paving the way for personalized medicine. Although the beneficial effects of epi-drugs are gaining more attention, the number of epigenetic compounds used in clinical practice remains low, suggesting the need to develop more selective epi-drugs. In this review, we present a list of new promising epi-drugs for the treatment of cardiovascular diseases, with a focus mainly on HFpEF. The therapeutic effect of these drugs is due to the impact on at least one of the three main epigenetic mechanisms: DNA methylation, histone modification, and non-coding RNA.","PeriodicalId":11859,"journal":{"name":"Eurasian heart journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139248832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
