Abstract:

Objective To investigate the predictive value of serum soluble triggering receptors expressed on myeloid cells 1 (sTREM1) combined with ABCD-3I score in the prediction of recent acute ischemic stroke (AIS) in patients with transient ischaemic attack (TIA). Methods A total of 288 TIA patients were selected, and they were divided into the low-risk group (102 cases), the intermediate-risk group (131 cases) and the high-risk group (55 cases) according to their ABCD-3I scores. In addition, the patients were sub-divided into the AIS group (41 cases) and the non-AIS group (247 cases) according to whether AIS occurred after 90 days. The clinical data such as age, sex and basic diseases were collected, and the serum sTREM1 level was detected by enzyme-linked immunosorbent assay. Results The age, proportion of diabetes, proportion of hypertension, low-density lipoprotein cholesterol (LDL-C) level, sTREM1 level and AIS ratio were significantly higher in the high-risk group than those in the intermediate-risk group and the low-risk group (P<0.05). The sTREM1 level was significantly higher in the intermediate-risk group than that in the low-risk group (P<0.05). The age, proportion of hypertension, LDL-C level, ABCD-3I score and sTREM1 level were significantly higher in the AIS group than those in the non-AIS group (P<0.05). Multivariate Logistic regression model analysis showed that both higher ABCD-3I score and higher sTREM1 level were risk factors for recent AIS in TIA patients (P<0.05). The area under the curve of ABCD-3I score and sTREM1 level in predicting AIS in TIA patients were 0.795 (95%CI: 0.723-0.867) and 0.755 (95%CI: 0.672-0.839) respectively, and the area under the curve increased to 0.881 (95%CI: 0.830-0.932) after the combination of ABCD-3I score and sTREM1 level. Conclusion Serum sTREM1 combined with ABCD-3I score has a high predictive value for recent AIS in TIA patients, and which has certain clinical application value.
