How Is Hypertrophic Cardiomyopathy Diagnosed?

HCM is diagnosed primarily with imaging of the heart by echocardiogram or cardiac MRI. Genetic testing is presently used only to assess risk of HCM. Those diagnosed with HCM are tested. 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. 



Tests Include:




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.
