Uncommon cause of a common disease.

摘要

Myocardial infarction is a common life-threatening condition. Multiple agents can be used to treat acute coronary syndrome (ACS). These therapeutic agents pose potential life-threatening complications when used outside the realm of the acute coronary syndrome. Hypertrophic cardiomyopathy (HCM) is a common inherited cardiac disorder, occurring in 1 in 500 individuals, which may mimic ACS. The hypertrophy most typically involves the septum in patients with HCM. As many as 25% of Japanese patients with HCM have predominately apical involvement. Apical hypertrophic cardiomyopathy (AHC) occurs in only 1 to 2% of the non-Japanese population. Despite its low incidence, physicians caring for patients with chest pain need to consider AHC in their differential diagnosis. We present the case of a patient with chest pain and electrocardiographic changes suggestive of ACS who was later found to have AHC.
