[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.

To study of the features of the clinical course and prognosis in patients with chronic heart failure with low ejection fraction (HFrEF) and atrial fibrillation (AF) depending on the width of the QRS complex. ⋯ These results highlight that patients with AF and a narrow QRS complex have the same poor prognosis as those with a wide QRS complex and require the close attention of cardiologists.

The purpose of the comments is the analysis of Professor Dmitry D. Pletnev's article Hypertension (experience in analyzing its genesis) from the point of view of modern ideas about arterial hypertension. Currently, a small number of publications of Professor D. ⋯ Pletnev, a Russian scientist and clinician, unjustly convicted in 1937, have been preserved. The small work includes not only a deep and critical analysis of the pathogenetic mechanisms of this disease, but also an assessment of diagnostic methods, as well as a detailed description of the clinical picture. The paper, published in 1935, remains relevant and of interest to clinicians and medical historians.
