The aim of a retrospective analysis performed at St. Antonius Hospital in the Netherlands was to investigate whether acute kidney injury (AKI) after coronary artery bypass grafting (CABG) can be attributed to intraoperative hypo-tension during cardiopulmonary bypass (IOH-CPB). The authors did not observe an association between IOH-CPB and AKI when they corrected this association for well-known confounders and suggest that future studies randomising patients to various IOH-CPB thresholds for CABG should be performed. Intra-operative and post-operative data were collected routinely in MetaVision, including the mean arterial pressure (MAP), which was monitored invasively and recorded every minute.
