Description

<jats:sec> <jats:title>Abstract</jats:title> <jats:p>Serum albumin (SA) is associated with inflammation and thrombosis, which are involved in acute aortic dissection (AAD). Our aim was to investigate the effect of SA level on survival in patients with AAD.</jats:p> <jats:p>We analyzed 777 patients with AAD. The patients were divided into hypoalbuminemia and non-hypoalbuminemia groups according to their AAD Stanford classification. Multivariable Cox regression was used to investigate the association between SA levels and in-hospital mortality in type A and B AAD.</jats:p> <jats:p>A total of 103 (13.3%) patients died in-hospital. The in-hospital mortality in type A and B patients with hypoalbuminemia was higher compared to those without (type A: 34.2% vs 13.9%, <jats:italic toggle="yes">P</jats:italic> <.001; type B: 7.9% vs 1.6%, <jats:italic toggle="yes">P</jats:italic> = .001). Kaplan–Meier analysis showed that survival was significantly lower in patients with hypoalbuminemia compared to those without, regardless of AAD type (type A: log-rank χ<jats:sup>2</jats:sup> = 14.71; <jats:italic toggle="yes">P</jats:italic> <.001; Type B: log-rank χ<jats:sup>2</jats:sup> = 10.42; <jats:italic toggle="yes">P</jats:italic> = .001). After adjusting for confounding factors, hypoalbuminemia was an independent predictor of in-hospital mortality in patients with either type A (HR, 2.492; 95% confidence interval [CI], 1.247–4.979; <jats:italic toggle="yes">P</jats:italic> = .010) or type B (HR, 8.729; 95% CI, 1.825–41.736; <jats:italic toggle="yes">P</jats:italic> = .007).</jats:p> <jats:p>SA is independently associated with increased in-hospital mortality in both type A and B AAD.</jats:p> </jats:sec>
