Elevated Pulse Pressure in Anesthetized Subjects Before Cardiopulmonary Bypass Is Associated Strongly With Postoperative Acute Kidney Injury Stage.

Objective: To investigate whether pulse pressure (PP) in anesthetized patients undergoing cardiac surgery before and after cardiopulmonary bypass (CPB) is associated with higher postoperative acute kidney injury (AKI) stage.

Design: Retrospective cohort of 597 patients undergoing cardiac surgery.

Setting: Single academic health care center.
