Stroke is a leading cause of morbidity, mortality, and disability in patients undergoing cardiac surgery. In this issue of Anesthesiology, Sun et al. evaluate the association between the severity and duration of intraoperative hypotension and postoperative stroke in patients undergoing cardiac surgery. The study’s findings suggest that mean arterial pressure may be an important intraoperative therapeutic hemodynamic target to reduce the incidence of stroke in patients undergoing cardiopulmonary bypass.
