Key result
Complete coronary revascularization assessed 6 months post-CABG was associated with a 15-year survival rate similar to that of the general Danish population.
Why the study?
Does complete coronary revascularization after CABG improve long-term survival to match the general population in patients treated for angina?
Cohort (n=198)
Does complete coronary revascularization after CABG improve long-term survival to match the general population in patients treated for angina?
Complete revascularization after CABG, if maintained at 6 months postoperatively, restores 15-year survival rates to match those of the general population.
Supports complete revascularization post-CABG for population-level survival; leaves open prospective validation in current-era patients.
To evaluate the influence of complete coronary revascularization after coronary artery bypass grafting (CABG) on long-term survival, we reviewed the records, including reports of coronary angiography, of 198 patients (25 women). Coronary artery bypass grafting was performed in the period 1973-1982, when the patients' mean age was 52.5 years. No significant (p < 0.05) difference in survival in the first 15 postoperative years was found between the patients judged to have complete revascularization at coronary angiography 6 months after CABG and the general Danish population. Complete revascularization by extensive grafting should improve survival of patients treated for angina. If the revascularization remains complete at coronary angiography assessment 6 months postoperatively, the 15-year survival rate can be expected to equal that in the general population.

Bertelsen et al. (1997) conducted a cohort in Angina post-CABG (n=198). Complete coronary revascularization vs. General Danish population was evaluated on 15-year survival. Complete coronary revascularization assessed 6 months post-CABG was associated with a 15-year survival rate similar to that of the general Danish population.
