Case

Elevated BNP despite apparent functional capacity

A case on how to approach a discordance between self-reported functional capacity and an elevated preoperative BNP.

Teaching points

  • Self-reported walking ability is not equivalent to confirmed functional capacity — ask about hills and stairs.
  • When FC and BNP conflict, BNP elevation is a signal to consider further evaluation, not a reason to cancel surgery.
  • Elevated BNP prompts investigation into the underlying cause, not automatic deferral.
