摘要
Objective: To measure the preoperative uric acid (UA) concentration in patients with type A aortic dissection (TAAD), and to assess its value in predicting in-hospital mortality. Methods: A total of 747 patients with TAAD between January 2016 and December 2022 were enrolled. The patients were divided into a survivor group and a non-survivor group. The clinical data of the two groups were compared. Univariate and multiple logistic regression analyses were performed to determine risk factors related to in-hospital mortality. Results: Compared with survivors, non-survivors had significantly higher serum uric acid levels (486.84 +/- 127.59 vs 419.49 +/- 141.02, P = 0.040). The incidence of in-hospital death increased along with higher UA levels (3.8% vs 0.7%, P = 0.007). Serum UA >= 373.5 mmol/L had 89.5% sensitivity and 41.3% specificity for predicting in-hospital death (area under the curve = 0.659, 95% CI: 0.554-0.765, P < 0.05). In the multivariable logistic model, Serum UA >= 373.5 mmol/L was independently associated with inhospital mortality (OR = 1.022, 95% CI: 1.000-1.044, P = 0.048). Conclusion: Serum UA resulted as an independent predictor of adverse prognosis in patients with TAAD, and thus could be used as an effective tool for the risk-stratification of patients with TAAD.
