We systematically searched Medline and Scopus to identify all observational cohort studies published before January 2020 that compared outcome (short‐term mortality) in patients with AAD with high vs low levels of baseline NT‐proBNP combining terms “brain natriuretic peptide” and “aortic dissection.” A meta‐analysis was conducted using the generic inverse variance method. The gene discussed is NPPB; the disease is Aortic dissection.
