Abstract
BACKGROUND: Transient ischemic attack (TIA) is a super warning for cerebral infarction stroke, thus probe of sensitive biomarker for TIA diagnosis and prognosis can contribute to make an optimal intervention plan. OBJECTIVE: This study was conducted to explore the value of ischemic modified albumin (IMA) and microRNA-12miR-126 on the diagnosis of posterior circulation TIA and the prediction of secondary cerebral infarction. STUDY DESIGN: This study was conducted as a longitudinal prospective research. METHODS: The levels of serum IMA and miR-126 at 3h, 6h and 12h after TIA onset were analyzed in 106 patients, then the predictive value of IMA and miR-126 for secondary cerebral infarction were tested. RESULTS: A significant increase of serum IMA and a decrease of miR-126 were observed after TIA onset (P = 0.000),simultaneously a significant negative correlation was found between serum IMA for 3 h and miR-126 for 12 hr=-0.401, P = 0.000. Both IMA and miR-126 were significant associated with the secondary cerebral infarction. CONCLUSION: Early detection of IMA and miR-126 is of great value in diagnosing posterior circulation TIA and predicting the secondary cerebral infarction.
