Examination of cardiac functions during acute attack and remission period in children with familial Mediterranean fever.

Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease characterized by recurring serosal inflammation. Cardiac involvement in FMF commonly manifests as pericarditis and pericardial effusion; however, there is limited research on myocardial function. This study aimed to assess cardiac functions during active inflammation and remission periods of FMF patients and investigate the cardiac effects of inflammation during the attack period.
