Eighty-two consecutive patients undergoing reoperation for coronary revascularization from January 1980 to November 1990 were reviewed to determine early and late results and predictors of survival. Seventy patients were male and 12 female; age ranged from 36 to 75 years (mean 56.4 +/- 8.1). All were symptomatic for angina. The mean interval between first and second operation was 62.8 +/- 47.8 months (range 1 to 220 months). Angiographic indications for reoperation were: graft failure (34.1%), progression of atherosclerosis in the native coronary circulation (6.1%) and combination of the two (59.8%). Mean ejection fraction was 45.9 +/- 10.2 (range 11 to 67). Surgical indication was elective in 79.3%, urgent in 14.6% and emergent in 6.1%; 199 grafts were performed (2.4 +/- 1 grafts/patient). Hospital mortality was 6.1% (5 cases). Late mortality was 5.2% (4 cases). Actuarial survival rate (including hospital mortality) was 87.9% at 3, 5 and 10 years. Multivariate analysis identified left main stenosis (p = 0.00001), family history of coronary disease (p = 0.003), urgent/emergency operation (p = 0.015) as predictors of increased in-hospital mortality; postoperative myocardial infarction (p = 0.002) and preoperative heart failure (p = 0.01) as predictors of increased late mortality. Follow-up of in-hospital survivors (mean interval 42.7 +/- 25.8 months, range 3 to 120 months) documented 27 cardiac major events (other than death) in 24 patients (32.9%). Actuarial rates of freedom from major cardiac events were 70%, 52.9% and 48.1% at 3, 5 and 10 years respectively. Multivariate analysis identified preoperative ejection fraction (p = 0.01) as predictor of recurrence of angina and preoperative heart failure (p = 0.02) as predictor of occurrence of cardiac major events.

Abstract

Eighty-two consecutive patients undergoing reoperation for coronary revascularization from January 1980 to November 1990 were reviewed to determine early and late results and predictors of survival. Seventy patients were male and 12 female; age ranged from 36 to 75 years (mean 56.4 +/- 8.1). All were symptomatic for angina. The mean interval between first and second operation was 62.8 +/- 47.8 months (range 1 to 220 months). Angiographic indications for reoperation were: graft failure (34.1%), progression of atherosclerosis in the native coronary circulation (6.1%) and combination of the two (59.8%). Mean ejection fraction was 45.9 +/- 10.2 (range 11 to 67). Surgical indication was elective in 79.3%, urgent in 14.6% and emergent in 6.1%; 199 grafts were performed (2.4 +/- 1 grafts/patient). Hospital mortality was 6.1% (5 cases). Late mortality was 5.2% (4 cases). Actuarial survival rate (including hospital mortality) was 87.9% at 3, 5 and 10 years. Multivariate analysis identified left main stenosis (p = 0.00001), family history of coronary disease (p = 0.003), urgent/emergency operation (p = 0.015) as predictors of increased in-hospital mortality; postoperative myocardial infarction (p = 0.002) and preoperative heart failure (p = 0.01) as predictors of increased late mortality. Follow-up of in-hospital survivors (mean interval 42.7 +/- 25.8 months, range 3 to 120 months) documented 27 cardiac major events (other than death) in 24 patients (32.9%). Actuarial rates of freedom from major cardiac events were 70%, 52.9% and 48.1% at 3, 5 and 10 years respectively. Multivariate analysis identified preoperative ejection fraction (p = 0.01) as predictor of recurrence of angina and preoperative heart failure (p = 0.02) as predictor of occurrence of cardiac major events.
