Analysis of epidemiological characteristics and prognosis based on 1,343 cases of aortic dissection from a regional single center

This study indicates that AD predominantly affects middle-aged and elderly males with hypertension, with distinct temporal and seasonal patterns. Acute onset, chest pain, type A dissection, higher heart rate, non-surgical, and larger false lumen diameter significantly increase the risk of in-hospital mortality, highlighting the need for increased vigilance in emergency clinical practice.
