The association between diabetes mellitus and hypokinetic cardiomyopathy is frequent. We report a case of diabetes and hypokinetic cardiopathy in a 40-year-old man which led to the hypothesis of maternally inherited diabetes and deafness (MIDD) due to a mitochondrial disease. This diagnosis was confirmed by genetic testing which showed a DNA A3243G mutation in the mitochondria, the prevalence of which is 1-2% in diabetes mellitus. Cardiac abnormalities are frequent (18-34% of patients depending on the series) and the co-existence of left ventricular hypertrophy and systolic dysfunction is suggestive of this disease. Some authors have proposed co-enzyme Q as a treatment to improve the left ventricular ejection fraction and insulin secretion.
