Incidence of cardiac sarcoidosis in those with extra-cardiac disease without known cardiac involvement - a CMR study

Background Cardiac death is the leading cause of mortality in patients with sarcoidosis. However, the incidence of cardiac sarcoidosis in those with extracardiac disease has yet to be formally examined. Cardiovascular magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE) may identify the myocardial infiltration of cardiac sarcoidosis (CS), and thus allow risk stratification of these at risk individuals. We therefore investigated the incidence of CS in patients with extracardiac sarcoidosis without cardiac manifestations using CMR-LGE.
