To compare efficiency and specific features of transthyretin amyloid staining by different histological dyes and thus to assess their suitability for diagnostic purposes. ⋯ The most reliable method for histochemical diagnosis of ATTR is the Congo red staining with subsequent analysis using fluorescence or confocal microscopy. For diagnostic screening, the use of Sodium sulphate-Alcian blue staining method is highly promising. Metachromatic stains are less effective for ATTR diagnosis.

In recent decades, advances in molecular biology have led to a change in understanding the inheritance mechanisms and development of cardiological diseases of predominantly genetic origin, such as hypertrophic and dilated cardiomyopathies, familial hypercholesterolemia, etc. This knowledge made it possible to develop fundamentally new drug interventions. Programs for detecting cardiac diseases of predominantly genetic origin have been created, including genetic counseling and testing. Competence in this area is becoming a necessary part of a cardiologist's job.

[The risk of developing cardiovascular disease in bipolar disorder. Biological factors and therapy].
Bipolar disorder (BD) is one of the most common mental disorders characterized by alternating episodes of mania/hypomania and depression, as well as the possibility of developing mixed conditions. Correct and timely diagnosis of BD is important due to the presence of a high suicidal risk and a high predisposition to the development of cardiovascular disease (CVD). The risk of CVD is higher in ВD than in other mental disorders. ⋯ The predisposition of patients of BD to CVD is beyond doubt. It is necessary to consider the peculiarities of the course of BD and conduct active monitoring and preventive measures to reduce the risk of developing life-threatening CVDs. Further research focused on the pathogenetic relationship between BD and CVD could provide more insight into this area.

Iron deficiency is frequent in patients with chronic heart failure (CHF) with a prevalence of 50%, and its frequency varies depending on the study groups. The presence of iron deficiency limits erythropoiesis, leading to the development of anemia over time in patients with CHF, regardless of gender, race, and left ventricular ejection fraction (LVEF). Observational studies demonstrate a higher prevalence of iron deficiency in women and in patients with higher NYHA (New York Heart Association) functional class, decreased LVEF, increased brain natriuretic peptide (NT-proBNP), or increased high-sensitivity C-reactive protein. ⋯ At the same time the use of intravenous iron therapy is safe and improves symptoms, exercise capacity and quality of life in patients with heart failure with reduced ejection fraction and iron deficiency, which has been shown both in international placebo-controlled trials and meta-analyses. The use of iron carboxymaltose should improve CHF symptoms, exercise capacity and quality of life in patients with CHF and LVEF45%. Intravenous iron therapy has also been shown to reduce readmissions for CHF in patients with an LVEF50% who have recently been hospitalized for worsening CHF.

Determination of the clinical and prognostic value of the equivalent density of calcium deposits (EDCD) of coronary arteries in patients with stable coronary heart disease (CHD) and concomitant osteopenic syndrome (OS) after coronary artery bypass grafting (CABG), based on five-year follow-up. ⋯ According to the results of the study the negative prognostic significance of the low EDCD of coronary arteries in relation to mortality, myocardial infarction, and revascularization in patients after CABG, regardless of the presence of concomitant OS.
