Artery Bypass Grafting

Background and Aims: Cardiopulmonary bypass induces a systematic inflammatory response, which is partly understood by investigation of peripheral blood cytokine levels alone; the lungs may interfere with the net cytokine concentration. We investigated whether lung ventilation influences lung passage of some cytokines after coronary artery bypass grafting. Material and Methods: In total, 47 patients undergoing coronary artery bypass grafting were enrolled, and 37 were randomized according to the ventilation technique: (1) No-ventilation group, with intubation tube detached from the ventilator; (2) low tidal volume group, with continuous low tidal volume ventilation; and (3) continuous 10 cm H2O positive airway pressure. Ten selected patients undergoing surgery without cardiopulmonary bypass served as a referral group. Representative pulmonary and radial artery blood samples were collected for the evaluation of calculated lung passage (pulmonary/radial artery) of the pro-inflammatory cytokines (interleukin 6 and interleukin 8) and the anti-inflammatory interleukin 10 immediately after induction of anesthesia (T1), 1 h after restoring ventilation/return of flow in all grafts (T2), and 20 h after restoring ventilation/return of flow in all grafts (T3). Results: Pulmonary/radial artery interleukin 6 and pulmonary/radial artery interleukin 8 ratios ( p = 0.001 and p = 0.05, respectively) decreased, while pulmonary/radial artery interleukin 10 ratio ( p = 0.001) increased in patients without cardiopulmonary bypass as compared with patients with cardiopulmonary bypass. Conclusions: The pulmonary/radial artery equation is an innovative means for the evaluation of cytokine lung passage after coronary artery bypass grafting. The mode of lung ventilation has no impact on some cytokines after coronary artery bypass grafting in patients treated with cardiopulmonary bypass.

Objective: To evaluate the feasibility and results of performing cardiopulmonary exercise test (CPET) in coronary artery disease (CAD) patients before elective coronary artery bypass grafting surgery (CABG). CPET has been increasingly employed in the evaluation of preoperative risk before noncardiac surgeries, but is still underutilized before cardiac surgery and may be useful, as clinical risk scores for preoperative assessment before cardiac surgeries have several limitations. Methods: Patients with CAD underwent CPET within 1 week before CABG. Oxygen consumption, oxygen pulse, oxygen consumption at the anaerobic threshold, minute ventilation/carbon dioxide relationship slope (VE/VCO2 slope), oxygen uptake efficiency slope (OUES) and heart rate recovery (HRR) were analyzed. The occurrence of complications during the test was recorded. Results: Twenty-eight patients (75% men), aged 61 (8) years, underwent preoperative CPET. There were no complications during CPET, even though 71.4% were interrupted by signs or symptoms of ischemia, and only 57% of the patients reached the anaerobic threshold.  Conclusions: Preoperative CPET before elective CABG was feasible and safe. However, a large proportion of patients did not achieve the anaerobic threshold. Therefore, VE/VCO2 slope, OUES and HRR may be the most useful CPET variables in the preoperative period.
