title: [Acromegalic cardiomyopathy manifesting as asymptomatic ventricular premature contractions at regular medical check up: a case report].
abstract: A 32-year-old Japanese male visited our hospital on May 20, 2004 because of ventricular premature contractions detected at a regular medical check up. He had been asymptomatic with adequate exercise capacity. However, echocardiography findings and Holter monitoring showed impaired left ventricular systolic function associated with left ventricular dilation and non-sustained ventricular tachycardia on June 26. Coronary angiography did not show significant stenosis. Different types of non-sustained ventricular tachycardia could be induced by an electrophysiologic test, but not sustained ventricular tachycardia. The physical findings, such as enlargement of the nose, lips, hands and feet, suggested endocrinologic abnormalities, and growth hormone and somatomedin-C levels were elevated. Therefore, the final diagnosis was cardiomyopathy caused by acromegaly.
