Consistently replicated independent predictors of poor outcomes include preoperative shock, renal dysfunction, and elevated inflammatory markers such as a neutrophil-to-lymphocyte ratio (NLR) greater than 6.0. Long-term prognosis is further dictated by aortic remodeling, where a residual patent false lumen (FL) and an in-hospital aortic volume growth rate serv…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
