Hypertrophiccardiomyopathy is not related to ischemic heart disease but 50% of cases are familial and may be related to genetic mutations in genes encoding for cardiac contractile elements.
Familialhypertrophiccardiomyopathy (FHCM) is a genetically heterogeneous cardiac disease transmitted as an autosomal dominant trait. It is the leading cause of sudden cardiac death (SCD) in youth.
