A comparative study of right ventricular histopathologic findings and clinical profiles in 174 cases with @entity1121 ( @entity1121 ), 145 cases with @entity384 ( @entity384 ), and 241 cases with idiopathic @entity943 and/or conduction disturbance with significant myocardial pathology [Electric disturbance type of @entity296 ( @entity14315 )], totaling 560 cases, was made in order to clarify the role of @entity2401 in these conditions. @entity1987 ( @entity1987 ) was defined by assessing serial biopsy findings in nine cases with @entity2401 . The @entity1987 was observed in three cases with @entity1121 (1.7%), 22 with @entity384 (15%), and 21 with @entity14315 (8.7%). The incidence of @entity1987 was significantly higher in @entity384 and @entity14315 than in @entity1121 (P less than 0.001). The typical pattern of onset of @entity2401 , i.e., high fever, @entity1729 , and gastrointestinal symptoms preceding @entity299 within 10 days, was recognized in one case with @entity1121 , eight with @entity384 , and 6 of 123 cases with @entity14315 . The incidence was higher in @entity384 and @entity14315 than in @entity1121 (P less than 0.05). Of 46 cases with @entity1987 , 12 (26%) showed this pattern, on the other hand only 3 of 377 cases (0.8%) without @entity1987 did so (P less than 0.0001). Familial occurrence was not found in any of the 46 cases with @entity1987 but was found in 38 of the 377 cases without @entity1987 (P less than 0.01). This study indicates that @entity2401 may often be the causative agent of @entity296 , especially @entity384 and @entity14315 . It is also noticed that familial occurrence of the cases with @entity1987 was never seen.
