Text: The use of off-pump CABG, as compared with on-pump CABG, significantly reduced the rates of blood-product transfusion (50. 7 % vs. 63. 3 % ; relative risk, 0. 80 ; 95 % CI, 0. 75 to 0. 85 ; P < 0. 001), reoperation for perioperative bleeding (1. 4 % vs. 2. 4 % ; relative risk, 0. 61 ; 95 % CI, 0. 40 to 0. 93 ; P = 0. 02), acute kidney injury (28. 0 % vs. 32. 1 % ; relative risk, 0. 87 ; 95 % CI, 0. 80 to 0. 96 ; P = 0. 01), and respiratory complications (5. 9 % vs. 7. 5 % ; relative risk, 0. 79 ; 95 % CI, 0. 63 to 0. 98 ; P = 0. 03) but increased the rate of early repeat revascularizations (0. 7 % vs. 0. 2 % ; hazard ratio, 4. 01 ; 95 % CI, 1. 34 to 12. 0 ; P = 0. 01).
