[A clinical case of reverse left ventricular remodeling in patient with pathogenic TTN mutation. Case report].

Dilated cardiomyopathy (DCM) is a leading cause of heart failure, sudden cardiac death, and heart transplantation in young patients. The causes of DCM are varied and include genetic factors and metabolic, infectious, toxic and others factors. Today it is known that germline mutations in more than 98 genes can be associated with the occurrence of DCM.

Interleukin 6 Signalling in Heart Failure With Preserved and Reduced Ejection Fraction.

Aim: Identification of interleukin-6 (IL-6) signaling pathways in patients with chronic heart failure (CHF).

Material And Methods: The diversity of IL-6 effects is due to the presence of classical signaling and trans-signaling pathways. The study included 164 patients with CHF hospitalized for acute decompensated heart failure (ADHF), of which 129 had reduced left ventricular ejection fraction (HFrEF), and 35 had preserved ejection fraction (HFpEF).

[A rare variant in the TTR gene (p.E112K) is associated with systemic amyloidosis and a new symptom - skin hyperemia in response to ethanol intake: family segregation analysis, literature review, and a clinical case. Case report].

Transthyretin amyloidosis (ATTR-amyloidosis) is a systemic disorder associated with extracellular deposition in the tissues and organs of amyloid fibrils, transthyretin-containing insoluble protein-polysaccharide complexes. The change in transthyretin conformation, leading to its destabilization and amyloidogenicity, can be acquired (wild type, ATTRwt) and hereditary due to mutations in the gene (variant, ATTRv) [1, 2]. Hereditary ATTR-amyloidosis has an earlier onset and greater phenotypic diversity.

[Difficulties in differential diagnosis of the AL- and ATTR-cardiac amyloidosis. Case report].

The article presents a clinical case describing a complex differential diagnosis of cardiac amyloidosis types and verification of the diagnosis of AL-amyloidosis.

[Possibilities of instrumental determination of volemic status in patients with acute decompensation of chronic heart failure].

Aim: To evaluate and compare the accuracy of volemic status determination by remote dielectric sensing with computed tomography (CT) in patients with acute decompensated heart failure.

Materials And Methods: In 28 patients volemic status was determined by ReDS (remote dielectric sensing), chest computed tomography (CCT), and chest X-ray twice during hospitalization (the day of admission and the day of discharge from the hospital). The ReDS measurements were then compared with CT data using software that allows the use of semi-automated tools to determine mean lung density (MLD).
