@entity299 was suspected in 95 @entity1 with severe blunt @entity764 of whom 93 did not require hospitalization. @entity908 kinase (CK) MB isoenzyme activity was elevated over 4.0 U/l in 10 (10.5%) @entity1 (CK MB positive) by between 2% and 8% (mean +/- SE 4.1 +/- 0.6%), when the total CK was 296 +/- 74 (mean +/- SE). Two @entity1 had a pericardial rub. M-mode echocardiography was performed on 16 @entity1 : 7 CK MB positive (CK MB+) and 9 CK MB negative (CK MB-) without the physician's knowledge of the CK MB status of the @entity1 . The left ventricular end-diastolic diameter, in healthy subjects 48.3 +/- 4.9 mm, was increased to 55.4 +/- 1.8 mm (p less than 0.01) in CK MB+ @entity1 and to 56.3 +/- 6.0 mm (p less than 0.01) in CK MB- @entity1 . The end-systolic left ventricular diameter, in healthy subjects 36.7 +/- 5.2 mm, was increased to 42.4 +/- 6.7 mm (p less than 0.01) in CK MB+ @entity1 and to 41.3 +/- 6.5 mm (p less than 0.01) in CK MB- @entity1 . The mean ejection fraction was 48.6 +/- 11.0 in CK MB+ and 53.6 +/- 11.8 in CK MB- group. @entity854 occurred in all CK MB+ @entity1 in 2 or more left ventricular regions and in 7 out of 9 CK MB- @entity1 in 1 or 2 regions. The regional motion pattern was @entity2845 with sharp systolic deflections at abnormal areas and @entity2915 on normal segments. Aortic root was enlarged in all @entity1 with contusion and CK MB+. There was no apparent increase in left atrial size. "Flattened" ST-segment and T-waves were seen in 5 CK MB+ @entity1 but not in the CK MB- @entity1 .(ABSTRACT TRUNCATED AT 250 WORDS)
