Does an elevated preoperative Blood Urea Nitrogen to Serum Albumin Ratio (BAR) predict unfavorable outcomes in patients undergoing cardiac surgery?
Elevated preoperative blood urea nitrogen to serum albumin ratio (BAR) may serve as a prognostic marker for adverse outcomes in cardiac surgery patients.
Increased preoperative BAR is a potent predictor of unfavorable outcomes in patients undergoing cardiac surgery.
