Prognostic impact on Type B acute aortic dissection with renal insufficiency: A single-center study

Aims: The aim was to study the impact of renal insufficiency on type B acute aortic dissection (AAD), in terms of in-hospital mortality and long-term survival. Materials and Methods: A total of 241 consecutive patients with type B AAD from 2007 to 2014 were enrolled. Based on estimated glomerular filtration rate, two groups were formed: Group A, with e-GFR 0.05). Both groups received main cardiovascular drugs and/or interventional therapies (P > 0.05). Group A had longer coronary care unit stays than Group B (P < 0.05). Multivariate logistic regression model showed white blood cell (WBC) count (odds ratio [OR], 1.107; 95% confidence interval [CI], 1.016-1.206; P < 0.05), e-GFR < 60 ml/min/1.73 m2 (OR, 4.809; 95% CI, 1.716-13.480; P < 0.05), and in-hospital hypotension (OR, 13.87; 95% CI, 2.544-75.591; P < 0.05) as significant predictors for in-hospital mortality. This was also significant in Cox regression analysis: WBC count (Hazard ratio (HR), 1.108; 95% CI, 1.029-1.194, P < 0.05), e-GFR
