Predictive value of ischemia-modified albumin level in secondary cerebral infarction after transient ischemic attack in anterior circulation / 中华老年医学杂志

ABSTRACT

Objective To predict a value of ischemia modified albumin (IMA) levels for assessing secondary cerebral infarction in patients with transient ischemic attack (TIA) in anterior circulation.Methods 105 patients with TIA in anterior circulation admitted to the hospital within 3 hours were retrospectively studied.Combined with ABCD2 score,the correlations of IMA levels at 3 h,6 h and 12 h with secondary cerebral infarction after anterior circulation TIA were analyzed.Results IMA level was 75.28 u/L within 3h after TIA,and the sensitivity and specificity of TIA in anterior circulation were 66.7％ and 76.2％ respectively.In the total of 105 patients,16 cases (15.2％) suffered from secondary cerebral infarction within 7d,and 21 cases (20.0％) within 8～30d.The serum IMA levels were (87.43±19.89)U/L,(63.88±12.51)U/L and (61.21±12.28)U/L at 3h,6h and 12h after TIA,respectively.A simple analysis showed that there was a linear correlation between the IMA level and ABCD2 scores (P=0.000,r=0.666).Kaplan-Meier survival curve analysis showed that the increased IMA level within 3h,and moderate to high ABCD2 score were the risk factors for secondary cerebral infarction after TIA in anterior circulation (P=0.012,0.041).Conclusions Early detection of IMA has a clinical value similar to ABCD2 score to predict secondary cerebral infarction in patients with TIA in anterior circulation.
