Postoperative N-terminal pro-brain natriuretic peptide level in coronary artery bypass surgery with ventricular dysfunction after perioperative glucose-insulin-potassium treatment.

Objective: The aim of this study was to clarify the efficacy of perioperative glucose-insulin-potassium (GIK) infusion on preoperative and postoperative N-terminal (NT)-pro-brain natriuretic peptide (BNP) concentrations in patients with a low ejection fraction undergoing isolated on-pump coronary artery bypass graft (CABG) surgery.

Design: A double-blind, randomized, controlled study.

Setting: Modarres Hospital, Tehran, Islamic Republic of Iran.
