Relationship of Iron Deficiency, Anemia and Combination of Iron Deficiency With Anemia With Severity of Manifestations of Chronic Heart Failure. Additional Analysis of the Study "Prevalence of Iron Deficiency in Patients With Chronic Heart Failure in the Russian Federation (J-CHF-RF)".

Aim      To evaluate the role of iron deficiency (ID) identified by various criteria, anemia, and the combination of ID and anemia in determining the severity of the clinical course of chronic heart failure (CHF) in a retrospective analysis of data from 498 patients who participated in the ID-CHF-RF Russian multicenter program.Material and methods  ID was diagnosed by the following three criteria established by the European Society of Cardiology (ESC) and the Russian Society of Cardiology (RSC): 1) ferritin concentration <100 μg/l or ferritin concentration 100-299 μg/l in combination with a decreased transferrin saturation (TS) <20%; 2) ID criteria that showed a high sensitivity and specificity when compared with bone marrow morphology (BMM): TS ≤19.8% or serum iron (SI) ≤13 μmol/l; and 3) a composite index including a ferritin concentration <100 μg/l in combination with TS <20% and SI ≤13 μmol/l.

Female and Male Phenotypes of Iron Deficiency in CHF. Additional analysis of the «The Prevalence of Iron Deficiency in Patients With Chronic Heart Failure in the Russian Federation (J-CHF-RF)» study.

Aim    To evaluate the incidence of iron deficiency (ID) in men and women with chronic heart failure (CHF) and to compare clinical and functional indexes in patient with and without ID depending on the gender.Material and methods    An additional analysis of the study "Prevalence of Iron Deficiency in Patients With Chronic Heart Failure in the Russian Federation (ID-CHF-RF)" was performed. The study included 498 (198 women, 300 men) patients with CHF, in whom, in addition to iron metabolism, the quality of life and exercise tolerance (ET) were studied.

[Prognostic Value of Right Ventricular Dysfunction in Patients With Decompensated Chronic Heart Failure].

Aim      To determine the incidence rate and the practical significance of right ventricular dysfunction (RVD) in the development of cardiovascular complications in patients with decompensated chronic heart failure (DCHF).Material and methods  This prospective, single-site observational study included 171 patients older than 18 years with NYHA functional class (FC) II-IV chronic heart failure (CHF) who were hospitalized for DCHF. Standard and extended 2D and 3D echocardiography (EchoCG) was performed for all patients on admission.

[Risk Assessment of Adverse Outcomes in Symptomatic Patients With Arterial Hypertension and Chronic Heart Failure With Preserved Ejection Fraction Using THE HFA-PEFF Algorithm].

Aim      To study the incidence of heart failure (HF) in patients with arterial hypertension (AH), symptoms of HF, and left ventricular ejection fraction (LV EF) ≥50 % using a novel, modified HFA-PEFF diagnostic algorithm and to evaluate the liver hydration status and density depending on the established HF profiles and the prognostic significance of this algorithm.Material and methods  This study included 180 patients (median age, 72 years) with AH, symptoms of HF, and LV EF ≥50 %. The incidence of chronic HF with preserved ejection fraction (CHFpEF) was studied with the stepwise, modified HFA-PEFF diagnostic algorithm, and long-term outcomes were assessed at 3, 6, and 12 months of follow-up.

[The health of children of adolescent age delivered on time with light and large body mass].

The need to preserve and promote health of children determine one of the basic directions of development of public social policy. It is the most important strategic purpose of modern children health care, since from it depend health of the nation, increasing of life expectancy and national economic potential.Purpose of the study is to assess health status of children of adolescent age born at term with diagnosis "fetus with low birth weight for gestational age" and with large body mass.

Prognostic Value of Subclinical Pulmonary Congestion With Stress Ultrasound of the Lungs in the Development of Heart Failure in Patients With Primary Myocardial Infarction and Percutaneous Coronary Intervention.

Aim      To determine the clinical and prognostic significance of subclinical pulmonary congestion, as evaluated by stress ultrasound (stress-US) examination of the lungs, in the development of heart failure (HF) during the postinfarction period after acute myocardial infarction (AMI) and percutaneous coronary intervention (PCI).Material and methods  This prospective observational study included 103 patients with no history of HF and with the first AMI and successful PCI. Standard laboratory tests, including the measurement of NT-proBNP, echocardiography, stress-US of the lungs with a 6-min walk test (6MWT), were performed for all patients.

[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 %).

[The analytical review of normative and organizational support of functioning of perinatal service in The Russian Federation in 2000-2020].

The formation of code of normative legal documents ensuring activities of perinatal service is one of the most important, basic organizational technologies that determine activities of obstetrics and childhood services, contributing to increasing of natality, decreasing of maternal and infant morbidity, and maternal and childhood health care in general. The article presents analysis of formation of normative legal base that regulates functioning of perinatal service in the Russian Federation in 2000-2020. Actually, there is no objective prerequisites for fundamental alterations in the three-level system of medical care of women during pregnancy, labor, postpartum period and newborns.
