Hypertrophic cardiomyopathy is an autosomal dominant genetic disease. The signs and symptoms of disease vary in terms of history and clinical course, ranging from the development of acute heart failure or even sudden death, while other patients may remain asymptomatic throughout life. At the same time, there is a lack of correlation between the genotype and the phenotype of the disease. Thus, within a family, of two members carrying the same genetic abnormality, one may present a clinical manifestation of severe heart failure, the other remaining asymptomatic.
