Apical Hypertrophic Cardiomyopathy Among Non-Asians: A Case Series and Review of the Literature

Abstract

Apical hypertrophic cardiomyopathy (AHCM) has been rarely described in the Western world. More recently, improved sensitivity of diagnostic modalities and increased diagnostic awareness have increased detection rates, suggesting that the prevalence outside of Asia may have been previously understated. Hallmark features of AHCM include deeply negative, "giant" T-wave inversions on electrocardiography and a "spade-like" configuration of the left ventricle on ventriculography. We present two cases of AHCM, one in an African-American female and another in a Caucasian male.
