Abstract
Background Left ventricular noncompaction (LVNC) cardiomyopathy is a disorder that can be complicated by heart failure, arrhythmias, thromboembolism, and sudden cardiac death. The aim of this study is to clarify the genetic landscape of LVNC in a large cohort of well-phenotyped Russian patients with LVNC, including 48 families (n=214). Methods All index patients underwent clinical examination and genetic analysis, as well as family members who agreed to participate in the clinical study and/or in the genetic testing. The genetic testing included next generation sequencing and genetic classification according to ACMG guidelines. Results A total of 55 alleles of 54 pathogenic and likely pathogenic variants in 24 genes were identified, with the largest number in the MYH7 and TTN genes. A significant proportion of variants -8 of 54 (14.8%) -have not been described earlier in other populations and may be specific to LVNC patients in Russia. In LVNC patients, the presence of each subsequent variant is associated with increased odds of having more severe LVNC subtypes than isolated LVNC with preserved ejection fraction. The corresponding odds ratio is 2.77 (1.37 -7.37; p <0.001) per variant after adjustment for sex, age, and family. Conclusion Overall, the genetic analysis of LVNC patients, accompanied by cardiomyopathy-related family history analysis, resulted in a high diagnostic yield of 89.6%. These results suggest that genetic screening should be applied to the diagnosis and prognosis of LVNC patients.

Abstract
Aim. To analyze and demonstrate various phenotypes in patients with familial left ventricular noncompaction (LVNC).
Materials and methods. In 2013 was created a multicenter registry of LVNC patients. On its basis 30 families with a familial LVNC were selected.
Results. 30 LVNC families were selected from the register. From a total of 115 people (probands and relatives) in 71 (61.7%) LVNC was diagnosed (30 probands and 41 relatives with non-compact myocardial criteria). The most common type of remodeling in patients was the dilated type (DT) (n=30), the isolated LVNC with preserved ejection fraction (EF) was slightly less common (n=23), and the hypertrophic type (GT) was detected in 8 patients. 4 patients were diagnosed with the isolated LVNC with a reduced EF. 3 patients were with a combination of non-compact myocardium with congenital heart disease and with a combination of DT and GT (DT+GT). During the analysis of cases a combination of different phenotypes in the same family was observed. The largest number of families was diagnosed with a combination of DT and the isolated LVNC with preserved EF. The development of cardiovascular complications was associated with DT.
Conclusion. Family cases of LVNC had different types of myocardial remodeling and variants of clinical course. In one family a combination of different types of left ventricular remodeling is possible. DT is associated with the most severe clinical manifestations. The clinical picture of the isolated LVNC with preserved EF, is the most favorable, but in rare cases, serious clinical manifestations were observed.

Abstract
The review highlighted problems of reorganization of myocardical contractile and cytoskeletal proteins in cardiomyopathy (CM). The role of the genetic factors coding contractile proteins, proteins of thin and thick filaments, and also extracellular matrix proteins in processes of formation and development of hypertrophic (HCM) and dilated (DCM) cardiomyopathy are analyzed. The mechanisms responsible for the changes in cardiac proteins on regulation involved into force generation, its transfer, recycling ATP, impairments in transmembranal signals, that finally lead to cardiac cell dysfunction determining various manifestations of CM are considered.

Abstract
Complex clinical-laboratory investigation of children with congestive heart failure (CHF) developed on the basis of dilated cardiomyopathy and hypertrophic cardiomyopathy has been carried out. The development of CHF in children with cardiomyopathy was accompanied by changes of blood serum lactate, MB isoform of creatine phosphokinase, TNF-6, interleukin-6 (IL-6) (but not IL-2), and soluble receptors for IL-2 and IL-6.
