A Chinese engineer presented with non‐specific palpitation, atypical chest pain and normal electrocardiogram both at rest and during exercise, was documented to develop electrocardiographic evidence of left ventricular hypertrophy and abnormal isotopic cardiac scintigraphy during stress test within a period of three years. His echocardiogram remained unremarkable. Cardiac catheterisation and cineventriculogram confirmed the presence of apical hypertrophic cardiomyopathy, without any outflow tract obstruction or coronary artery disease. This case, together with 14 others detected recently in Hong Kong, will arouse the existence of this form of hypertrophic cardiomyopathy in the Chinese. The emergence of all diagnostic features in this patient within a short time will support an aetiological hypothesis that apical hypertrophic cardiomyopathy can be acquired in patients with genetic predisposition.
