To evaluate the prognostic impact of serum uric acid (SUA) on clinical outcomes in patients with acute decompensated heart failure, as well as identify the correlation between hyperuricemia and renal function and diuretic resistance in these patients. ⋯ We found no significant differences in the uric acid level in patients who reached the end point and those who did not reach it during the three-year follow-up. However, the found correlation between uric acid levels and diuretic resistance calls for further research.

Cardiovascular and respiratory diseases have been one of the leading causes of mortality in the world for over 15 years. According to the results of various studies, a clear connection was revealed between the incidence of influenza and the decompensation of cardiovascular diseases, which leads to the development of acute coronary syndrome, acute heart failure and myocardial infarction. ⋯ Influenza vaccination, especially in patients with high cardiovascular risk, is one of the most important secondary prevention measures. The article is dedicated to an overview of the problems of vaccination against influenza, the study of the prognosis of patients with high cardiovascular risk, as well as general points in the pathogenesis of influenza and cardiovascular diseases.

The article provides an overview of current information on the pathogenesis of COVID-19 and organ-specific lesions developing in this disease. The data on inflammation and its biochemical markers, on the features of coagulopathy, endothelial damage and microthrombosis are presented in detail. Particular attention is paid to the role of receptors for angiotensin converting enzyme type 2 and transmembrane serine protease type 2 in the development of organ-specific lesions in COVID-19. The pathogenesis of damage to the cardiovascular system is considered in detail with the presentation of data from foreign literature on changes in the myocardium and the author's results of transthoracic echocardiographic examination in patients who have undergone COVID-19.

Evaluation of the efficacy and safety of the modified refralon administration protocol for the relief of paroxysmal atrial fibrillation (AF). ⋯ Refralon has a high efficiency of relief (95%) of paroxysmal AF, while in almost half of cases (48.7%), SR recovery is achieved using the minimum dose of refralon 5 mg/kg. Despite the prolongation of the QTc500 ms recorded in 5% of cases, none of the patients developed Torsade de pointes after administration of the drug.

History of the discovery of fibrillation and defibrillation, stages of the development of the concept of defibrillation are described in the article. The differences in mechanisms of different types of defibrillation are given here. The modern state of defibrillation and future trends are discussed in our article.
