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.

Article Synopsis
  • The study compares clinical and lab data of chronic heart failure (CHF) patients with iron deficiency (ID) based on two different diagnostic criteria: AHA/ESC/RSC guidelines and a stricter definition involving low transferrin saturation (TSAT) and serum iron levels.
  • Among 498 patients analyzed, ID was identified in 83.1% using AHA/ESC/RSC criteria and 74.5% using the TSAT/serum iron criteria, with many patients meeting both sets of criteria.
  • Those diagnosed with ID based on the TSAT/serum iron criteria experienced more severe CHF symptoms, higher rates of anemia and diabetes, and showed significant differences in lab results and age compared to those diagnosed solely

The population of Russia consists of more than 150 local ethnicities. The ethnic diversity and geographic origins, which extend from eastern Europe to Asia, make the population uniquely positioned to investigate the shared properties of inherited disease risks between European and Asian ancestries. We present the analysis of genetic and phenotypic data from a cohort of 4,145 individuals collected in three metro areas in western Russia.

Aim: To study the clinical characteristics and prognosis of patients with functional class (FC) III-IV chronic heart failure (CHF) who meet the criteria for inclusion in the palliative care program.

Material And Methods: A short registry of severe CHF forms was conducted at 60 outpatient and inpatient clinics in the Samara region for one month (16.05.

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.
