title: [Dominant autosomal humeroperoneal syndrome with early contractures and cardiomyopathy (Emery-Dreifuss syndrome)].
abstract: At least seven members of a family coming from southern Germany (Franconia) have manifested Emery-Dreifuss syndrome within four generations. This syndrome is characterized by slowly progressing atrophic pareses, generally in a humeroperoneal distribution, premature joint contracture, and cardiomyopathy with reduction of functional capacity. Up to now four members of this family have died from cardiac causes between the age of 39 and 46 years. Three family members have now been thoroughly examined; they showed typical muscular atrophies and contractures. The two older patients were diagnosed as having a cardiomyopathy with a complete atrioventricular block and ventricular tachycardia. Electromyographic and histological findings indicate a primary neurogenic process. Regular cardiological examinations combined with effective therapy (for example, implantation of a cardiac pacemaker and treatment with antiarrhythmic drugs) will be necessary in treating the serious arrhythmias. Progressive myocardial insufficiency required heart transplantation in one of our patients, which was successfully performed. Macroscopic and microscopic examination of the explanted heart showed a dilatative cardiomyopathy with hypertrophy and dilatation of both atria and ventricles, differences in the diameters of individual heart muscle cells, and a predominately focal interstitial fibrosis.
