Abstract:
Objective:To investigate the relationship between different types of hemorrhagic transformation and serum uric acid in patients with acute cerebral infarction.Methods:The clinical data of 365 patients with acute cerebral infarction in Jinhua Central Hospital of Zhejiang Province from June 2018 to December 2020 were retrospectively analyzed. The clinical data and the serum uric acid level at the time of admission were recorded, and the occurrences of hemorrhagic infarction (HI) and cerebral parenchymal hematoma (PH) were counted. The risk factors of HI and PH in patients with acute cerebral infarction were analyzed by multivariate Logistic regression analysis.Results:Among 365 patients, 328 cases had no hemorrhagic transformation (control group); 37 cases (10.1%) had hemorrhagic transformation, with 20 cases of HI (HI group) and 17 cases of PH (PH group). The uric acid in PH group was significantly lower than that in control group and HI group: (243.59 ± 61.49) μmol/L vs. (307.84 ± 80.12) and (305.45 ± 94.99) μmol/L, and there was statistical difference ( P<0.05); there was no statistical difference in uric acid between control group and HI group ( P>0.05). The patients was divided into 3 groups according to the tertiles of serum uric acid, uric acid ≤ 264.9 μmol/L was in 121 cases (Ⅰ group), 265.0 to 338.8 μmol/L was in 122 cases (Ⅱ group) and ≥338.9 μmol/L was in 122 cases (Ⅲ group). The rate of PH in Ⅲ group was significantly lower than that in Ⅰ group: 0.8% (1/122) vs. 8.3% (10/121), and there was statistical difference ( P<0.05). Taking patients without hemorrhage transformation as a reference, multivariate Logistic regression analysis result showed that diabetes, atrial fibrillation and large-area infarction were independent risk factors of HI in patients with acute cerebral infarction ( P<0.01); the age, large-area cerebral infarction, thrombolytic therapy, platelet count and uric acid were independent risk factors of PH in patients with acute cerebral infarction ( P<0.05 or <0.01). Conclusions:In patients with acute cerebral infarction, higher serum uric acid is independently correlated with lower PH, and has no correlation with HI. Serum uric acid level has certain value in predicting PH.
