The Correlation Between The Clinical Features Of TIA And The DWI Manifestations

This paper is a MeTa-analysis study on the correlation between the clinical features of TIA patients and their Diffusion Weighed Imaging (DWI) results. We searched the major medical databases home and abroad (CNKI, SCI, PubMed and Cochrane Library ) and finally 17 literatures, which involved 1,541 subjects, were identified as conforming to the inclusion criteria. In this paper, we analyzed the correlation between the DWI results and such parameters the age and the gender of the TIA patients, hypertension, diabetes, hyperlipidemia, the smoking history, the TIA or cerebral apoplexy history, the ischemic heart disease history, artrial fibrillation, carotid stenosis, symptoms lasting for≥1h, dyskinesia, dysphonia and paresthesia. The study results indicate that age, diabetes, the TIA or cerebral apoplexy history, artrial fibrillation, symptoms lasting for≥1h, dyskinesia and dysphonia are significantly correlated with DWI(+). The correlations cannot be sufficiently verified because there were relatively fewer high quality researches. And further studies should be required to identify the hierarchy of the cerebral apoplexy risk of TIA patients according to these factors to establish the selection criteria for different intervention measures.
