Incidence and significance of @entity2294 in @entity1 with @entity583 ( @entity583 ) have not been established. To evaluate these issues, we studied prospectively 138 consecutive @entity1 with @entity583 . An echocardiogram was obtained in each 1, 3, and 10 days and 3 and 6 months after admission. Fifty four @entity1 with @entity1459 and 57 without @entity299 were studied as controls. Echocardiographic diagnostic criteria of @entity2294 were established from 33 additional @entity1 undergoing surgery. @entity2294 was found in 28% of @entity1 with @entity583 . Twenty-five percent of @entity1 with @entity583 had @entity2294 on the third day, vs 8% of @entity1 with @entity1459 (p less than .02) and 5% of @entity1 without @entity299 (p less than .01). At 1, 3, and 10 days and 3 and 6 months prevalence of @entity2294 was 17%, 25%, 21%, 11%, and 8%, respectively. There was no case of tamponade. @entity2294 was more common in anterior @entity583 (p less than .02) and in @entity1 with @entity712 (p less than .05) but it was not significantly associated with @entity2396 , peak @entity908 kinase-MB, the level of anticoagulation, or mortality. Thus, @entity2294 is a common event in @entity1 with @entity583 (incidence of 28%), but does not result in specific complications. The reabsorption rate of @entity2294 is slow and, in our experience, mild or moderate @entity2294 does not preclude heparin therapy.
