Wen D, et al. - Researchers designed this single-center prospective study assessing the predictive value of N-terminal pro-brain natriuretic peptide (NT-proBNP) and aortic diameter for in-hospital mortality in acute aortic dissection (AD). In the setting of the University hospital in China, they enrolled 122 patients with acute AD. Findings revealed the occurrence of acute AD in-hospital mortality in independent correlation with NT-proBNP ≥569.75 pg/ml and aortic diameter ≥40 mm. In-hospital mortality was more specifically predicted with NT-proBNP ≥1325.6 pg/ml or aortic diameter ≥47 mm. Better prediction for in-hospital mortality with higher sensitivity could be made using NT-proBNP and aortic diameter together.
