Unstructed Abstract
This is the first study to
investigate the impact of the
corticosteroids therapy on the efficacy of an upgrade to cardiac
resynchronization therapy (CRT) therapy in patients with cardiac
sarcoidosis (CS). The echocardiographic response to an upgrade to CRT
was lower in patients with CS than in those with other etiologies of
non-ischemic cardiomyopathy. The patients with CS who had taken
corticosteroids before the upgrade to CRT (group 1) demonstrated the
lowest echocardiographic response. However, the cumulative freedom from
hospitalizations from worsening heart failure and cardiovascular death
did not significant differ between patients with CS and those with other
etiologies. Especially, group 1 patients presented with the lowest rate
of cardiovascular death and heart failure hospitalizations.
