摘要："Objective: To investigate whether plasma trimethylamine N-oxide (TMAO) levels might predict early neurological deterioration (END) in individuals with acute ischemic stroke.Study Design: Cohort study.Place and Duration of the Study: Jiulongpo District Hospital of Traditional Chinese Medicine, Chongqing City, China, from January 2020 to December 2021.Methodology: Patients presenting with ischemic stroke were classified into the END group and the non-END group. The National Institutes of Health Stroke Scale (NIHSS) total increasing by 2 points or more within 72 hours of admission was the definition of the END. Plasma TMAO levels were determined by high-performance liquid chromatographic and tandem mass spectrometry.Results: Twenty-six (25%) of the 104 patients, diagnosed with END exhibited higher TMAO levels after admission (median 1.438 vs. 0.449 nmol/mL, p=0.001). Elevated plasma TMAO levels were significant predictors of END in univariate logistic anal-ysis. After controlling for age, gender, and cardiovascular risk factors in the multivariate conditional logistic regression model, the plasma TMAO levels in the END group remained significantly higher than those in the non-END group (OR=6.646, 95% CI 2.434-18.147, p<0.001). In receiver operator characteristic (ROC) analysis, the sensitivity and specificity of TMAO in distin-guishing the END group and the non-END group at 0.564 nmol/mL cutoff value were 0.885 and 0.679, respectively.Conclusion: According to this research, the development of END on admission in patients with acute ischemic stroke may be positively correlated with the elevation in plasma TMAO levels."
