Preoperative therapy with angiotensin-converting enzyme inhibitors in cardiac surgery patients: is there any impact on postoperative renal function?

Preoperative therapy with angiotensin-converting enzyme inhibitors (ACEI) is common in patients undergoing cardiac surgery. The aim of this study was to evaluate the still-debated impact of preoperative use of ACEI on postoperative renal function in cardiac surgery patients [1],[2].
