Cardio myopathies are a group of diseases, which affect the myocardium of the heart (kumar and Clarke). They can be differentiated into groups with different characteristics: dilated, hypertrophic, restrictive and arrythmyogenic right ventricular hypertrophies (report of the 1995 WHO).
Hypertrophic cardiomyopathy (HCM), a familial condition affecting the heart, is characterised by unexplained and variable hypertrophy of the left ventricular wall and the inter-ventricular septum in the absence of any alternate causes such as aortic stenosis or hypertension (Oxford Concise Medical Dictionary, Kumar and Clarke). It differentiates itself from other cardiovascular diseases by the fact that onset can occur during any phase of life. (maron 2002)
It is the most common cause of sudden cardiac death in young people with a predilection for children and adults under 30-years of age (Maron BJ, 2010). The risk of sudden death decreases with age and occurs significantly less frequently in those over the age of 60 with morbidity and mortality more likely to be related to other co-morbidities within this age group (Maron et al. 2011). Other severely affected patients may experience chest pain, tachyarrhythmia or heart failure to a varying degree (Oxford Concise Medical Dictionary).
Diagnosis is based on electrocardiography and echocardiography with pharmacological interventions successfully controlling symptoms in some patients while others need cardiac catheterization or surgical
