| Abstract: | A 45-year-old woman of Moroccan origin developed a dilated cardiomyopathy during clozapine treatment for a psychosis that did not respond to conventional antipsychotics. The onset of her illness was acute with chest pain. She subsequently developed shortness of breath and oedema of the face and legs. The cardiomyopathy appeared to be partially reversible after the clozapine was halted. Cardiomyopathy during the use of clozapine is rarely described in the literature, although myocarditis is a known complication. The cause of cardiomyopathy during the use of clozapine is not known. Myocarditis might evolve into cardiomyopathy. There are indications that myocarditis is caused by an allergic reaction to clozapine. It is advised that clozapine treatment should only be initiated under the close supervision of a psychiatrist, and that during the use of clozapine one should be alert to the risk of cardiac complications. |
