We have documented a unique instance of diabetic ketoacidosis(DKA)-induced stress-related cardiomyopathy (CMP) in a 46-yr-oldCaucasian female with type I diabetes mellitus. In times ofstress, tissues with high capacity for aerobic metabolism, likemyocardium, can preferentially change their metabolic substrateto ketones. The myocyte has a decreased ability to metabolizeglucose and free fatty acids in stress CMP. To the best of ourknowledge this is the first report of stress CMP complicatingDKA. A possible mechanism for the same is hypothesized.
