Does elevated preoperative BNP (>382 pg/mL) predict 30-day all-cause mortality in patients undergoing cardiac surgery?
Preoperative serum BNP > 382 pg/mL is an independent predictor of 30-day all-cause mortality in patients undergoing CABG or valve surgery, suggesting its utility for preoperative risk stratification.
