Key result

Pre-operative BNP levels predicted new postoperative cardiac events with an area under the curve of 0.85 (CI 0.72-0.98, p=0.001), where a value >170 pg/ml had 82% sensitivity and 79% specificity.

Why the study?

Overview

May support preoperative BNP for risk stratification in emergency noncardiac surgery; hypothesis-generating and requires prospective validation.

Study Design

Type

Observational (n=40)

Structured PICO

Does pre-operative BNP level predict postoperative cardiac events and mortality in patients undergoing major emergency non-cardiac surgery?

P
Population
40 patients undergoing major emergency non-cardiac surgery
I
Intervention
Pre-operative B-type natriuretic peptide (BNP) level measurement
O
Outcome
Composite of a new postoperative cardiac event, and/or development of significant ECG changes, and/or cardiac deathcomposite

Main Result

Effect estimate: AUC 0.85 (95% CI 0.72-0.98)

p-value: p=0.001

Pre-operative BNP levels > 170 pg/ml show good sensitivity and specificity for predicting early postoperative cardiac events in patients undergoing major emergency non-cardiac surgery.

Limitations

  • Small sample size
  • small study

Cite This Study

Cuthbertson et al. (2007) conducted an observational in Major emergency non-cardiac surgery (n=40). Pre-operative B-type natriuretic peptide (BNP) levels was evaluated on New postoperative cardiac event, and/or development of significant ECG changes, and/or cardiac death (AUC 0.85, 95% CI 0.72-0.98, p=0.001). Pre-operative BNP levels predicted new postoperative cardiac events with an area under the curve of 0.85 (CI 0.72-0.98, p=0.001), where a value >170 pg/ml had 82% sensitivity and 79% specificity.
