OBJECTIVE
To explore the clinical characteristics of patients with inherited hypertrophic cardiomyopathy.
METHODS
The clinical characteristics, electrocardiogram, serum chemistry and diagnostic methods were retrospectively investigated in 5 patients with inherited hypertrophic cardiomyopathy.
RESULTS
The electrocardiograms of all patients were abnormal, with prominent left ventricular voltage and ST-T changes. One male patient with clinicopathological features of early onset, muscle weakness, ventricular preexcitation, elevations of two serum proteins and intracytoplasmic vacuoles containing autophagic material and glycogen in biceps brachial muscle cells was diagnosed Danon's disease. Mitochondrial cardiomyopathy was diagnosed in one male patient with early onset, short PR interval and biopsy findings of ragged-red fibers in biceps brachial muscle. Three patients were diagnosed as Fabry's disease with clinical characteristics including pain and acroparesthesias, angiokeratoma and decrease of alpha-galactosidase A activity.
CONCLUSIONS
Some of the rare inherited hypertrophic cardiomyopathy might easily be clinically misdiagnosed as hypertrophic cardiomyopathy, systemic and careful case history inquiring and specific relevant examinations would help to make the right diagnosis in these patients.
