Case

Elevated BNP before surgery

A case on how to interpret an elevated preoperative BNP and what steps to take next.

Teaching points

  • BNP is a marker of cardiac wall stress, not a standalone diagnostic criterion for heart failure.
  • Elevated BNP before surgery is a signal to assess the underlying cause, not to simply proceed.
  • Consider cardiology referral and echocardiography when preoperative BNP is elevated.
