Does preoperative BNP concentration predict postoperative outcomes in patients undergoing cardiac surgery?
Preoperative BNP is a valuable and easily measurable biomarker for predicting adverse postoperative outcomes, including mortality and prolonged hospital stay, in patients undergoing cardiac surgery.
No takes yet. Share an insight, caveat, or question.
Preoperative BNP may refine risk assessment before cardiac surgery; leaves open its incremental value beyond standard scores.
