Abstract
A 64-year-old woman with active acromegaly of 33 years' duration, severe carpal tunnel syndrome, and subclinical heart disease was treated with bromocriptine mesylate. Within eight months of therapy, basal growth hormone (GH) levels decreased from 90.0 to 7.0 ng/mL, and hand volume was reduced from 375 to 295 mL. Concomitantly, echocardiographic studies showed normal left ventricular size and function. Electromyographic studies demonstrated normal function in both median nerves. Bromocriptine may correct cardiac dysfunction and carpal tunnel syndrome in acromegaly either by reduction of GH oversecretion or by a direct effect of bromocriptine on dopamine receptors in the heart and peripheral nerve endings.
