Recurrence of XXXX after coronary artery bypass surgery: predictors and prognosis (CASS Registry). Coronary Artery Surgery Study.

@entity1 @entity951 @entity453 @entity86 @entity583
OBJECTIVES: This study sought to define the predictors and prognosis of @entity86 in @entity1 undergoing coronary artery bypass surgery. BACKGROUND: Angina recurs in the first postoperative year in 20% to 30% of @entity1 after coronary artery bypass surgery. The Coronary Artery Surgery Study Registry provides an opportunity to study the predictors and prognosis of @entity86 in a large sample. METHODS: All @entity1 with isolated coronary artery bypass surgery in the registry were identified, and anginal status was determined on a yearly basis. The influence of @entity951 on mortality, recurrent @entity583 and need for reoperation was determined. RESULTS: Angina recurred in the first year in 24% of @entity1 and by the sixth year in 40%. The significant predictors in a multivariate analysis were minimal @entity453 , @entity951 , use of vein grafts only, previous @entity583 , incomplete revascularization, female gender, smoking and younger age. In subsequent years important predictors were @entity951 in the first postoperative year, female gender, younger age and incomplete revascularization. The presence of @entity951 in the first postoperative year was associated with more frequent @entity583 (p = 0.04) and greater need for reoperation (p = 0.003) but did not affect survival during the 6-year follow-up period. CONCLUSIONS: These findings show that the predictors of @entity86 are features that are or could be predicted before bypass surgery. Thus, @entity1 with these features before bypass surgery could be advised that they would be more likely to experience @entity86 than those without these features. @entity86 is associated with an increased risk of late @entity583 and reoperation.
