BACKGROUND: Current strategies for management of acute @entity583 ( @entity583 ) include thrombolysis, angioplasty, and coronary bypass surgery singly or in combination. This study was designed to identify contemporary risk factors for coronary bypass surgery among @entity1 in this high-risk group. METHODS: Between June 1992 and December 1995, 1181 consecutive @entity1 underwent isolated coronary bypass surgery. Of these, 316 underwent coronary bypass surgery within 21 days of @entity583 . Mean age was 65 years (range, 33 to 87 years), and 73% were male. There were 166 @entity1 with @entity5749 (group 1), 107 @entity1 with @entity1459 requiring intravenous @entity1242 for a control of @entity63 (group 2), 20 @entity1 with angina requiring @entity661 for stabilization (group 3), and 23 @entity1 with severe postinfarction @entity63 complicated by @entity1455 (group 4). RESULTS: The overall in-hospital mortality rate was 5.1% (16 of 316), which was higher (p < 0.05) than the 2.5% (22 of 865) among @entity1 undergoing coronary bypass surgery without recent @entity583 . Mortality increased with severity of clinical preoperative status and was 1.2% in group 1, 3.7% in group 2, 20.0% in group 3, and 26% in group 4. Serious postoperative morbidity occurred in 7.3% of @entity1 . Multivariate logistic regression analysis identified preoperative @entity661 , left @entity67 , and @entity177 as the only independent correlates of mortality. CONCLUSIONS: Coronary bypass surgery can be safely performed in stable @entity1 at any time after acute @entity583 , with an operative mortality similar to elective surgery. Thus, in this era of medical cost containment, there is no apparent indication for prolonged stabilization attempts that delay surgery.
