Nephrogenic systemic fibrosis: considerations for the cardiologist.

The manuscript by Schietinger et al. (1) in this issue of iJACC (JACC: Cardiovascular Imaging) assesses patterns of late gadolinium enhancement (LGE) in the myocardium of chronic hemodialysis patients. The observation that the majority of LGE was not infarct related but was tied to the degree of left ventricular hypertrophy, particularly in dysfunctional segments, led the authors to suggest that LGE patterns within the myocardium may be able to serve as a clinical marker, perhaps for sudden death.
