[Prospects for use of Vericiguat in HFrEF: Implications of VICTORIA Trial Results. Advisory Board Summary].

In September 2021, an online meeting of the Council of Experts was held. The proposed focus of discussion was publishing the results of an international prospective, randomized, double-blind, placebo-controlled study VICTORIA. The objective of the VICTORIA study was evaluation of the efficacy and safety of supplementing a standard therapy with vericiguat at a target dose of 10 mg twice a day as compared to placebo for prevention of cardiovascular death and hospitalization for heart failure (HF) in patients with clinical manifestations of chronic HF and left ventricular ejection fraction <45% who have recently had an episode of decompensated HF.

[Cardiovascular effects of omega-3 polyunsaturated fatty acids: position of omega-3 polyunsaturated fatty acids in Russian and international guidelines. Council of Experts].

This Expert Council focuses on the meta-analysis of studies on the risk of atrial fibrillation (AF) in patients taking omega-3 polyunsaturated fatty acids (PUFA) and of data on the omega-3 PUFA treatment in patients with cardiovascular and kidney diseases.The major statements of the Expert Council: the meta-analysis of AF risk in patients taking omega-3 PUFA showed an increased risk of this arrhythmia. However, it should be taken into account that the risk of complications was low, and there was no significant increase in the risk of AF when omega-3 PUFA was used at a dose of ≤1 g and a standard dose of the only omega-3 PUFA drug registered in the Russian Federation, considering all AF episodes in the ASCEND study.

Conduction system pacing: promoting the physiology to prevent heart failure.

Cardiac conduction system pacing provides physiological ventricular activation by directly stimulating the conduction system. This review describes the two types of conduction system pacing: His bundle pacing (HBP) and left bundle area pacing (LBAP). The most significant advantage of HB pacing is that it can provide a regular, narrow QRS; however, the disadvantages are challenging implantation and a high risk of re-intervention due to lead dislodgement and the development of high pacing threshold.

[Cardiac contractility modulation in heart failure with reduced ejection fraction treatment].

Heart failure with reduced left ventricular ejection fraction (LV EF) (HFrEF) is a significant issue of health care due to increasing indexes of morbidity and mortality. The emergence of a number of drugs and implantable devices for the treatment of HFrEF has allowed improvement of patients' well-being and prognosis. However, high mortality and recurrent decompensated heart failure remain a substantial issue and stimulate the search for new methods of CHF treatment.

[Coenzyme Q-10 in the treatment of patients with chronic heart failure and reduced left ventricular ejection fraction: systematic review and meta-analysis].

Aim    The aim of the study was evaluation of the effect of the coenzyme Q10 (Q10) treatment on all-cause and cardiovascular mortality of patients with chronic heart failure (CHF). Q-10 increases the electron transfer in the mitochondrial respiratory chain and exerts anti-inflammatory and antioxidant effects. These effects improve the endothelial function and reduce afterload, which facilitates the heart pumping function.

[Iron deficiency in Russia heart failure patients. Observational cross-sectional multicenter study].

Aim    To evaluate the prevalence of iron deficiency (ID) in Russian patients with heart failure (HF).Material and methods    Iron metabolism variables were studied in 498 (198 women, 300 men) patients with HF. Data were evaluated at admission for HF (97 %) or during an outpatient visit (3 %).

Role of anticoagulants in therapy and prevention of recurrent venous thromboembolism in patients with cancer: a meta-analysis of randomized trials with apixaban.

Background    Venous thromboembolic complications (VTEC) are a major non-oncological cause of death of patients with malignant neoplasm (MNP). This determines the high significance of antithrombotic therapy for the treatment and secondary prevention of VTEC in this population. During recent years, low-molecular weight heparins (LMWH) have been a "gold standard" for the treatment of cancer-associated venous thrombosis (CAVT).

[Features of a new corOnavirUs infection course and optioNs therapy DEpending on the andRogenic status (FOUNDER): androgenic status in men with COVID-19 and its relationship with the disease severity].

Objective: Analysis of androgen status in men hospitalized with a moderate COVID-19 and its relationship with the severity of the disease.

Materials And Methods: The study included 152 males with a confirmed diagnosis of COVID-19 based on the results of a positive PCR for the SARS-CoV-2 virus and/or computed tomography of the lungs hospitalized at the MSU University Clinic due to the moderate and severe COVID-19.

Hyponatraemia in heart failure: time for new solutions?

Hyponatraemia is very common in heart failure (HF), especially in decompensated patients. It is associated with increased mortality and morbidity and considered a marker of advanced disease. Recognition of hyponatraemia and its causes may help guide treatment strategy.

Effect of 24-hour blood pressure and heart rate on the prognosis of patients with reduced and midrange LVEF.

Aim    Optimal combination therapy for chronic heart failure (CHF) currently implies the mandatory use of at least four classes of drugs: renin-angiotensin-aldosterone (RAAS) system inhibitors or angiotensin receptor blocker neprilysin inhibitors (ARNI); beta-adrenoblockers (BAB); mineralocorticoid receptor antagonists; and sodium-glucose cotransporter 2 inhibitors. Furthermore, many of these drugs are able to decrease blood pressure even to hypotension and alleviate tachycardia. This study focused on the relationship of 24-h blood pressure (BP) and heart rate (HR) with the prognosis for CHF patients with sinus rhythm and left ventricular ejection fraction (LV EF) <50 % as well as on suggesting possible variants of safe therapy for CHF depending on the combination of studied factors.

The ability of modern therapy to improve the prognosis of patients with HF: role of angiotensin neprilysin inhibitors and sodium-glucose cotransporter inhibitors.

Major principles for treatment of chronic heart failure with reduced left ventricular ejection fraction <40% (HFrEF) include a "triple neurohormonal blockade" as a main approach. However, in recent 6 years, two new classes of drugs for the treatment of HFrEF have appeared, which beneficially influence the prognosis. These drugs are angiotensin receptor neprilysin inhibitors (ARNI) and type 2 sodium-glucose cotransporter 2 (SGLT2) inhibitors.

The event was devoted to the discussion of the correct use of research data of "real clinical practice" in decision making.

[Expert consensus regarding treatment of iron deficiency in stable and decompensated patients with heart failure].

In recent years there has been significant interest in treating iron deficiency (ID) in patients with heart failure (HF) due to its high prevalence and detrimental effects in this population. As stated in the 2020 Russain HF guidelines, Intravenous ferric carboxymaltose remains the only proven therapy for ID.This document was prompted by the results from the recent AFFIRM-AHF trial which demonstrates that treatment of ID after acute HF decompensation reduces the risk of future decompensations.
