Neurology:血浆三甲胺N-氧化物水平升高与卒中损伤增加之间的关系

2020-01-07 xing.T MedSci原创

由此可见,缺血性卒中患者血浆TMAO水平高于健康对照者。入院时血浆TMAO水平升高是急性缺血卒中患者严重程度和梗死体积的独立预测因子。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,该研究旨在调查血浆三甲胺N-氧化物(TMAO)水平升高是否与初始卒中严重程度和梗死体积有关。

这项横断面研究纳入了377例急性缺血性卒中患者和50例健康对照者。入院时评估血浆TMAO水平,用弥散加权成像和NIH中风量表(NIHSS)测量卒中的梗塞体积和临床卒中的严重程度。轻度卒中定义为NIHSS得分<6。

缺血性卒中患者的血浆TMAO水平高于健康对照者(中位数为5.1 vs. 3.0μmol/L; p<0.001)。调整血管危险因素后,TMAO每增加1 µmol/L,NIHSS得分增加1.13分(95%置信区间[CI]为1.04–1.29;p<0.001)和梗死体积增加1.69mL(95%CI为1.41–2.03; p<0.001)。入院时,159名患者(42.2%)经历了轻度卒中,其血浆TMAO水平低于中度至重度卒中的患者(中位值3.6 vs. 6.5 µmol/L; p<0.001)。在预测中度至重度卒中时,血浆TMAO水平的受试者工作特征曲线下的面积为0.794(95%CI为0.748–0.839;p<0.001),最佳临界值为4.95μmol/L。中度至重度卒中TMAO≥4.95μmol/L的敏感性和特异性分别为70.2%和79.9%。

由此可见,缺血性卒中患者血浆TMAO水平高于健康对照者。入院时血浆TMAO水平升高是急性缺血卒中患者严重程度和梗死体积的独立预测因子。
