 Postgraduate Medicine: Hypertrophic cardiomyopathy
The prevalence of hypertrophic cardiomyopathy in the general population is estimated to be from 0.2% to as high as 4.9% when echocardiographic screening is used (1).
Although sudden death from hypertrophic cardiomyopathy is uncommon, it may be the only indication of the condition; annual incidence is about 6% in children and young adults and 1% in adults 45 to 60 years of age (2).
The most common form of hypertrophic cardiomyopathy is diffuse hypertrophy of the ventricular septum and anterolateral free wall (70% to 75% of cases) (figure 2: not shown), followed by basal septal hypertrophy (10% to 15%), concentric hypertrophy (<5%), hypertrophy of the lateral wall (1% to 2%), and apical hypertrophy (5).

 HCMA :: Hypertrophic Cardiomyopathy Association | HCM Overview | What is Hypertrophic Cardiomyopathy (HCM)?   (Site not responding. Last check: 2007-10-31)
Cardiomyopathy is a condition in which the muscle of the heart is abnormal in the absence of an apparent cause.
HCM is a primary and usually familial cardiac disorder with heterogeneous expression, unique pathophysiology, and a diverse clinical course, for which several disease causing mutations in the genes encoding proteins of the cardiac sacomere have been reported.
"Cardiomyopathy" itself is a very general term referring to any condition (and there are many) importantly affecting the heart muscle itself while "hypertrophic cardiomyopathy" refers to a specific and genetic condition which usually shows a familial pattern.

 Hypertrophic cardiomyopathy - hypertrophic obstructive cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is a disease of the myocardium (the muscle of the heart) in which a portion of the myocardium is hypertrophied (thickened) without any obvious cause.
Hypertrophic cardiomyopathy is attributed to mutation in one of a number of genes that encode for one of the sarcomere proteins (usually effecting either the a or ß myosin heavy chain on chromosome 14 q11.2-3).
Feline hypertrophic cardiomyopathy is the most common heart disease in cats; the disease process and genetics are believed to be similar to the disease in humans.

 Obstructive Hypertrophic Cardiomyopathy   (Site not responding. Last check: 2007-10-31)
Hypertrophic cardiomyopathy (HCM) is a primary disease of cardiac muscle characterized by a thickening of the left ventricular wall and often predominantly affecting the interventricular septum.
In the form of asymmetrical septal hypertrophy known as idiopathic hypertrophic subaortic stenosis, the proximal septal hypertrophy obstructs LV outflow (Panel 2), which is the form presented in the case study.
It is important for the patient, family members, and physicians to be aware that the diagnosis of HCM may be associated with significant psychological stress that may be as serious as the associated physical disabilities.

 Mendelian Inheritance in Man Document Reader
Hypertrophic cardiomyopathy can be caused by mutations in any one of 4 genes that encode proteins of the cardiac sarcomere: cardiac troponin T (TNNT2; 191045) on chromosome 1, alpha-tropomyosin (TPM1; 191010) on 15, myosin-binding protein (MYBPC3; 600958) on 11, and MYH7 on 14 (Maron, 1997).
McKenna (1993) estimated that 40 to 50% of cases of hypertrophic cardiomyopathy (CMH; 192600) are due to mutations in the MYH7 gene.
