Table 3 Multivariable predictors of in-hospital mortality and organ malperfusion (derivation cohort)

From: Prognostic dynamic nomogram integrated with metabolic acidosis for in-hospital mortality and organ malperfusion in acute type B aortic dissection patients undergoing thoracic endovascular aortic repair

Variables Multivariate
OR 95% CI P value
Base excess*     < 0.001
 Moderate risk versus low risk 4.98 2.01–12.32 0.001
 High risk versus low risk 8.40 2.09–33.84 0.003
Renal dysfunction 3.99 1.62–9.81 0.003
D-dimer ≥ 5.44 μg/mL 3.82 1.55–9.46 0.004
Albumin ≤ 30 g/L 4.51 1.88–10.80 0.001
Diameter ≥ 55 mm 6.51 1.89–22.45 0.003
  1. The predictive model was adjusted by pH, lactate, bicarbonate, decreased peripheral arterial pulse, hypertension, coronary artery disease, stroke, anemia, estimated glomerular filtration rate < 60 mL/min/1.73 m2, extent of the dissection, blood supply of visceral arteries (coeliac artery, superior mesenteric artery, left renal artery and right renal artery)
  2. OR, odds ratio; CI, confidence interval
  3. *Base excess was divided into low risk group (> − 5), moderate risk group (− 10 to − 5) and high risk group (≤ − 10)
