MAIN PROBLEM: The prognostic value of soluble lectin-like oxidized low-density lipoproteinreceptor-1 (sLOX-1) for stroke was unclearly. This study aimed to investigate the association between sLOX-1 and recurrent stroke in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA).
METHODS: Data were obtained from the Third China National Stroke Registry. Eligible cases consisted of 400 patients who developed recurrent stroke within 1-year follow-up, 800 controls were selected using age- and sex-matched with a 1:2 case-control ratio. Conditional logistic regressions were used to evaluate the association between sLOX-1 and recurrent stroke.
RESULTS: Among 1200 patients included in this study, the median (interquartile range) of sLOX-1 was 247.12 (132.81-413.58) ng/L. After adjustment for conventional confounding factors, the odds ratio with 95% confidence interval in the highest tertile versus the lowest tertile was 2.23 (1.61-3.08) for recurrent stroke, 2.31 (1.64-3.24) for ischemic stroke, 2.30 (1.66-3.19) for combined vascular events within 1-year follow-up. Furthermore, the addition of sLOX-1 to a conventional risk model had an incremental effect on predictive value for recurrent stroke (C-statistics 0.76, p < 0.0001; integrated discrimination improvement 13.38%, p < 0.0001; net reclassification improvement 55.39%, p < 0.0001). Similar results were observed when the timepoint was set up as 3 months. Subgroup analysis showed the association between higher sLOX-1 and recurrent stroke was more pronounced in patients with a history of stroke (p for interaction = 0.0062).
CONCLUSIONS: sLOX-1 was positively associated with the risk of recurrent stroke, which may be a candidate biomarker to improve risk stratification of recurrent stroke.
