BACKGROUND: Although successful recanalization of the occluded artery is achieved, no-reflow phenomenon (NRP) becomes a main contributor to poor prognosis in patients with acute ischemic stroke. There are some laboratory results to represent biomarkers of the no-reflow phenomenon. However, few studies have characterized the metabolomic signature of NRP. Using high-performance liquid chromatography-tandem mass spectrometry (LC-MS)-based method, this study aims to characterize the plasma metabolites associated with NRP.
METHODS: A total of 34 patients with acute large vessel occlusion in anterior circulation who underwent successful thrombectomy with final angiographic expanded Treatment in Cerebral Infarction score of 2c-3 score were enrolled (19 without NRP and 15 with NRP). Fasting venous blood collected 24 h after the procedure was centrifuged and subjected to metabolomic analysis.
RESULTS: We identified 29 differentially expressed plasma metabolites, the majority of which were phosphatidylcholine (PC) species. Among them, PC(20:4(5Z,8Z,11Z,14Z)/P-16:0) showed the most significant alteration and exhibited robust predictive performance (AUC = 0.846). The most prominently disrupted metabolic pathway was glycerophospholipid metabolism, particularly PC-mediated pathways, which appeared to play a central role in the association with of NRP.
CONCLUSION: This study depict the plasma metabolic profile of NRP patients following stroke thrombectomy, and discover that phosphatidylcholine-dominated metabolites and related pathways may play a potential role in the occurrence of NRP. These metabolic biomarkers demonstrate promising discriminative ability and may help identify high-risk patients at an early stage, providing new targets for mechanism research and therapeutic intervention.
