How Is Hypertrophic Cardiomyopathy Diagnosed?
HCM is identified through one of several paths, presentation of symptoms, clinical findings, or family history. To know if HCM is present in the heart most commonly will begin with imaging of the heart by echocardiogram or cardiac MRI. Genetic testing may be used but must begin with someone who has already displayed clinical HCM (the heart is already thick). If an HCM-promoting mutation is found, their close relatives can then be tested for the same mutation, to see if they are at risk of developing HCM.
It is not uncommon to see people diagnosed with asthma, anxiety attacks, panic attacks or some forms of depression, only to find that the underlying cause of the symptoms is HCM.
