Key result
Repeated CABG for recurrent angina yields a ~40% angina-free rate at five years.
Why the study?
The cost effectiveness and clinical outcomes of repeated coronary artery bypass grafting for recurrent angina were not well established.
Is repeated coronary surgery for recurrent angina cost-effective and does it improve functional status?
Population
49 patients reoperated for recurrent angina after first-time CABG
Comparison
Second time CABG vs first time CABG hospital expenses
Design
Cohort study
Follow-up
Mean 3.7 years, range 10-108 months

May warrant consideration in selected recurrent angina cases; leaves open cost-effectiveness and randomized comparisons to PCI.

Is repeated coronary surgery for recurrent angina cost-effective and does it improve functional status?
Repeated coronary surgery for recurrent angina is associated with reasonable mortality and good late functional results, though at a higher cost than first-time CABG.
Dougenis et al. (1992) conducted a cohort in Recurrent angina (n=49). Repeated coronary artery bypass grafting (second time CABG) was evaluated on 5-year actuarial probability of angina-free interval. Repeated coronary surgery for recurrent angina achieved a 1- and 5-year angina-free probability of 87.5% and 40%, respectively, with reasonable mortality.
