Protective effect of pyridoxal-5-phosphate (MC-1) on perioperative myocardial infarction is independent of aortic cross clamp time: results from the MEND-CABG trial.

MC-1 decreased the incidence of CV death and MI (CK-MB >or=100 ng/mL) during the first 90 days after CABG in the MEND-CABG trial. Although longer aortic clamping time increased the risk of cardiovascular events, the protective effect of MC-1 was independent of ischemic time during CABG.
