Objective.Despite the high frequency — 0,2 % (1:500) population, hypertrophic cardiomyopathy (HCM) is still considered one of the most mysterious and misunderstood diseases of myocardium. Insidious pathology has neither specific anatomical and morphological, nor clinical features which makes it a delayed-action bomb: nobody is capable to predict when and what clinical symptoms develop. The clinical phenotype of HCM varies from latent course when the symptoms are absent till rapid progress of heart failure syndrome and sudden cardiac death due to severe arrhythmia. The review covers modern view on genetics, morphology and pathogenesis of HCM.
Clinical aspects, risk factors, results of selective coronary angiography, features of DNA-polymorphism (I/D polymorphism of gene ACE, isoalleles polymorphism gene APOE, SsTI polymorphism gene АРОСЗ, С677Т polymorphism of gene MTHFR, 4a/4b, G894T and T786C polymorphisms eNOs) in 89 women with a various degree of a coronary obstruction. In patients with sings of coronary artery atherosclerosis, familial history i heart disease was observed in most cases (greater degree on a line of mother). The obtained data show the reliable role of allele T, genotype CT gene MTHFRand gene-gene interaction of ACE and MTHFR genes (DD и СС, DD и СТ) in development of i heart disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
