[Cardiac changes in a case of mitochondrial encephalomyopathy]

In the present article the authors describe a case of a twenty-one year-old patient with a mitochondrial encephalomyopathy presenting cardiac changes. Mitochondrial encephalomyopathy a multisystemic disease is described in various publications having cardiac involvement although there are sparse references about cardiomyopathy in this same disease. In the present case, the patient had a syndrome of both Mitochondrial Encephalopathy, Lactic Acidosis and Stroke like episodes (MELAS) and Myoclonic Epilepsy and Ragged Red Fibers (MERRF). There were no significant changes in the cardiac conductivity studied by ECG but an echocardiographic pattern of hypertrophic cardiomyopathy was found.
