HPI: 21-year-old Female presents to the Emergency Department (ED) complaining of palpitations and left arm weakness with perioral numbness, which began just prior to arrival. The patient states the episode lasted 30 minutes before completely resolving on its own. In the ED, she denies any other complaints except for a mild headache. Patient notes she experienced a similar episode of palpitations yesterday afternoon, while resting, which she described as “skipping beats”. On further questioning, the patient admitted to being hospitalized to a NYC hospital 2 weeks ago where she had a Cardiac Echocardiogram done which showed “hypertrophy.” Patient never followed up with cardiologist as instructed. In the past, a doctor in her country prescribed her an unknown antihypertensive medication, which she took for one year but stopped taking it once she moved to NJ. Denies fever, dizziness, chest pain, and shortness of breath, recent travels, calf pain or swelling.

Working Diagnosis: Hypertrophic Cardiomyopathy (HCOM)
ED/Hospital course: Patient was given 324 mg of ASA and admitted to Telemetry with a diagnosis of Hypertrophic Cardiomyopathy. While still in the ED waiting for a bed on Telemetry the patient had multiple runs of non-sustained V-Tach and Cardiology was consulted. The patient was started on ASA and Metoprolol PO. A 2D ECHO was done which was consistent with HCOM. Patient remained stable on Telemetry for 3 days prior to discharge. The patient’s Troponin was trended daily, 0.308 in the ED, 0.288 on day 1 of admission, and 0.314 on day 2 of admission. Patient was told to follow up with Cardiology Clinic for possible AICD placement planning.
Hypertrophic cardiomyopathy (HCM) is one of the most common inherited cardiac disorders (affecting ~ 1 in 500 people) and is the number one cause of sudden cardiac death in young athletes. Annual mortality is estimated at 1-2 %.
