Myocardial lactate production (A) and oxygen extraction (B) (median, 25% and 75% percentiles, and range) before grafting (I), after completion of the first (II) and second (III) distal anastomoses, and 5 (IV) and 15 (V) minutes after the last proximal anastomosis was completed. ∗p = 0.02 compared with initial value (Scheffé’s test). p = and p = 0.01 for overall changes in lactate production and oxygen extraction, respectively, by analysis of variance.
