[Anticoagulant Therapy in Elderly Patients With Atrial Fibrillation].

Is this paper discuss problems of selection of anticoagulant therapy in elderly patients with atrial fibrillation, use of unreasonably low doses of anticoagulants, their risks and adherence to therapy is discussed in the paper.

[Tactics of Selection of Anticoagulant Therapy in Patients With Atrial Fibrillation and Ischemic Heart Disease].

In the clinical practice a physician quite often is at a loss due to "freedom of choice" granted by availability of direct oral anticoagulants (DOAC). If a patient with nonvalvular atrial fibrillation (AF) has indications for therapy with anticoagulants which DOAC should be preferred? What are benefits for a patient with ischemic heart disease and AF when definite NOAC is chosen and what are risks inherent of this choice? Answers to such questions are given in this paper.

[Hypertrophic Cardiomyopathy and Ischemic Heart Disease. Variants of Combination Pathology].

The issues of epidemiology and pathophysiology of hypertrophic cardiomyopathy (HCMP), as well as the search for its additional clinical-instrumental and genetic markers, environmental factors capable to influence the formation of its clinical variant and prognosis are subjects of great interest to the modern scientific community. Besides genetic markers of main neurohumoral systems, and morphofunctional parameters of intracardiac hemodynamics clinical course of the disease is influenced by a complex of concomitant pathology including ischemic heart disease (IHD), joining of which is possible in 10% of cases. IHD substantially aggravates course of HCMP and hampers selection of medical therapy.

This review presents modern data about a hereditary disease of myocardium - hypertrophic cardiomyopathy. The main features of its epidemiology, pathophysiological changes in intracardiac hemodynamics, formation of main clinical symptoms of the disease and variants of its clinical course are considered in terms of modern concepts. Much attention is given to characteristics of the variants of the disease and understanding of the formation of its clinical picture of each of them for the choice of the strategy for the management of these patients.

[Matrix metalloproteinases and hypertrophic cardiomyopathy].

Prognosis of patients with hypertrophic cardiomyopathy (HCMP) to a great extent is determined by clinical variant of the disease. As the system of matrix metalloproteinases (MMPs) plays an important role in development and progression of the processes of fibroformation and tissue remodeling polymorphisms of modifier genes regulating its components can influence clinical course of HCMP. Among possible markers of prognostication of the course of cardiovascular diseases the role of MMPs and their tissue inhibitors has been discussed.

Keeping in mind an important role of renin-angiotensin aldosterone system (RAS) in developing of cardiac remodeling and fibrosis, genetic polymorphisms coding its components could have influence with clinical variants of the course. Biomarkers could appear predictors of adverse. To examine the contribution of the RAS to developing of different hypertrophic cardiomyopathy (HCM) clinical variants of the course we studied 58 patients with HCM and controls comparable by age and gender.
