Supports durable outcomes after CABG for unstable angina; leaves open applicability to current patients and techniques.
Cohort (n=1,282)
Coronary bypass surgery for unstable angina is associated with excellent 5- and 10-year survival rates and significant long-term symptom relief.
Rahimtoola et al. (1983) conducted a cohort in Unstable angina (n=1,282). Coronary bypass surgery was evaluated on 10-year survival rate. Coronary bypass surgery for unstable angina resulted in a 10-year survival rate of 83%, with no significant differences in survival among clinical subgroups (P=0.49).
