BACKGROUND: The purpose of this study was to use serum markers for @entity296 damage to evaluate the effect of the severity of @entity7244 after 1-vessel off-pump coronary artery bypass grafting. METHODS: A consecutive series of 20 @entity1 with a totally occluded @entity6128 and only retrograde filling (group T; n = 10) or critical @entity850 (70%-99%) and only antegrade filling (group C; n = 10) were included in this study. One @entity1 in group C who displayed no increases in the levels of markers for @entity741 was excluded from the study because of the intraoperative repetition of the @entity254 . @entity908 kinase activity (CK), CK-MB activity, and CK-MB mass, myoglobin, @entity880 , and @entity6949 ( @entity6949 ) concentrations were determined in venous blood samples taken immediately before and after the @entity254 and at 4, 8, 12, 24, and 48 hours postoperatively. RESULTS: There were no perioperative @entity583 . One @entity1 in group T developed @entity998 48 hours after the operation and died after 1 month. His enzyme levels did not increase in the first 2 days postoperatively. @entity254 times were similar for the T and C groups (6.85 +/- 0.9 minutes versus 8.4 +/- 2.2 minutes, respectively; P =.069). The levels of all cardiac markers except @entity6949 increased significantly in the first 24 postoperative hours. CK-MB activity, CK-MB mass concentration, and @entity6949 concentration were not different between the 2 groups. Four @entity1 in each group were evaluated for the patency of the @entity254 , and all control angiography and myocardial scanning tests showed patent anastomoses and no @entity63 . CONCLUSIONS: One-vessel off-pump coronary artery bypass grafting can be performed safely in @entity1 with serious @entity6128 @entity850 and borderline antegrade blood flow without the need for any coronary collateral circulation support. A short @entity254 time prevents @entity296 during off-pump coronary surgery.
