Does Coronary Bypass Surgery Prolong Life Expectancy?
While relief of disabling angina following coronary artery bypass (CAB) generally has been accepted, the influence of CAB upon long- term survival has remained controversial. Comparison of survival data of nonrandomized surgical series with “noncurrent” historic medical controls  has been criticized frequently, most recently by Braunwald , In addition, the results of two recent multicenter cooperative studies of patients with unstable angina (NHLI) and stable angina (VAH), who were randomly assigned to medical or surgical therapy, show no difference in long-term survival.
