Results of foreign and Russian studies indicate a higher mortality rate of patients with concomitant cardiovascular diseases (CVD) due to the new coronavirus infection COVID-19. It has been proven that arterial hypertension, as one of the significant risk factors for the development of concomitant cardiovascular diseases, is associated with a more severe prognosis of COVID-19. This article presents the results of modern studies and large meta-analyzes of necessity and safety of the use of blockers of the renin-angiotensin-aldosterone system in patients with arterial hypertension and COVID-19. ⋯ It realizes various ways of lowering blood pressure by reducing the activity of the renin-angiotensin-aldosterone system, which is achieved by using an ACE inhibitor, and natriuresis due to diuretics. As an example, a highly effective fixed combination of drugs is considered, characterized by good tolerance, which consists of an ACE inhibitor lisinopril and a thiazide-like diuretic indapamide of prolonged action. The authors expressed the opinion that the appointment of the fixed combination drug Diroton Plus (Gedeon Richter) will contribute to effective control of blood pressure and organoprotection in conditions of increased thrombogenic and prooxidative potential, characteristic of COVID-19 both in the acute stage and within the post-COVID Syndrome.

The rate of major bleeding in patients with atrial fibrillation receiving oral anticoagulants is 25% per year. Gastrointestinal bleedings are at least a half of major hemorrhagic complications. Currently, there is no optimal scale to calculate the risk of bleeding, and therefore the search for clinical predictors of gastrointestinal bleeding remains relevant. ⋯ Searching for clinical predictors of gastrointestinal bleeding can identify patients receiving oral anticoagulants who is need of intensive monitoring risk factors to prevent the development of life-threatening bleeding and to provide with adequate anticoagulant therapy.

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.

Mineralocorticoid receptor antagonists have been successfully used for many years to treat patients with primary hyperaldosteronism, refractory arterial hypertension and chronic heart failure. The increased interest in this drug in recent years is due to new information about its antifibrotic and antiproliferative effects, both cardiac and extracardiac. The article also discusses the possibility of using spironolactone in patients with the new coronavirus infection SARS-CoV-2 (COVID-19).

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.
