Introduction
Acute type A aortic dissection (ATAAD) is a life-threatening cardiovascular condition that requires emergency surgery. Recently, the incidence of ATAAD has been increasing with the increasing incidence and poor control of hypertension in patients (1). With the great progress in various imaging technologies, our understanding of ATAAD has become clearer than it was previously. With the rapid development of materials technology and improved outcome expectations, the therapeutic strategies and concepts for ATAAD are constantly being updated. Therefore, further analysis and recognition of this critical and severe disease are needed to improve the clinical prognosis. The purpose of this study was to identify risk factors for in-hospital mortality in patients with ATAAD.
