HCM Patients
In speaking with patients who complain of symptoms consistent with HCM, ask if family members have been diagnosed with HCM, or if there is a family history of sudden cardiac arrest or died due to an unknown cardiovascular disease. When patients present with symptoms such as fatigue, fainting, shortness of breath, chest pain or heart palpitations without a known cause, suspect and test for HCM. With your help, patients whose lives have been restricted due to HCM may be able to reduce symptoms and comorbidities.
