Why the study?
Cardiac sarcoidosis and giant cell myocarditis are rare conditions with overlapping similarities but distinct clinical and histopathological features, prompting a direct comparison of their demographics, clinical presentation, and outcomes.
Population
Adult patients with CS (n = 71) or GCM (n = 21)
Comparison
CS vs GCM
Design
Single-center retrospective comparative cohort study
Follow-up
Median 33.5 months for CS and 2.98 months for GCM

GCM warrants closer surveillance than CS for rapid deterioration; leaves open whether etiology-tailored therapies alter outcomes.
Giant cell myocarditis has a significantly more fulminant clinical course with higher rates of biventricular failure and need for heart transplantation or death compared to cardiac sarcoidosis.
Bobbio et al. (2022) studied this question.
