Our patient was a young man with no known preexisting conditions that presented in cardiopulmonary arrest. We contrast this case with prior instances of non-toxigenic C. diphtheriae strain infection in the United States and the literature that suggests the resulting systemic infection can result in cardiogenic toxicity. We speculate on possible missed, pre-existing conditions that could have increased this patient’s susceptibility to poor clinical outcome.
