Figure 2 Pre-Operative NT-proBNP Predicts 30-Day Post-Operative Outcome After Adjustment for the Time Onset of Symptoms and the Logistic EuroSCORE

Adjusted odds ratios (OR) (diamonds) and 95% confidence intervals (CIs) (solid lines) comparing N-terminal pro-brain natriuretic peptide (NT-proBNP) levels on admission (in tertiles) and occurrence of major adverse events or death within a 30-day post-operative observation period. Major adverse event was defined as composite end point, including need for rethoracotomy, occurrence of post-operative heart failure, neurologic deficit, lung failure, renal failure, or sepsis. Final models were adjusted for logistic EuroSCORE and time of onset of symptoms. EuroSCORE = European System for Cardiac Operative Risk Evaluation.
