Figure 1 Pre-Operative NT-proBNP as Outcome Predictor in Surgery for Acute Type A Aortic Dissection

Pre-operative NT-proBNP in 104 patients undergoing emergency surgical repair of type A aortic dissection with respect to post-operative occurrence of major adverse events and 30-day mortality. Plots indicate median and interquartile range (range from the 25th to the 75th percentile). 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. MAE = major adverse event; NT-proBNP = N-terminal pro-brain natriuretic peptide.
