Plos One:复律后全血基因表达区分房颤和窦性心律

2018-03-25 李伟超 “罂粟花”微信号

这项研究表明,SLC25A20,PDK4和NT-proBNP作为生物标志物可区分房颤与窦性心律的增量效用。AF期间SLC25A20和PDK4的表达升高表明AF中能量代谢的重要作用。

背景

房颤动(AF)患者恢复窦性心律的治疗方案限制了长期复律成功率。 基因表达谱可能提供AF病理生理学的新见解。

通过比较电复律(ECV)前后的全血基因表达来识别生物标志物并改善我们对AF病理生理学的理解。

方  法

在46例持续性房颤患者接受ECV治疗后,在成功复律前1-2小时和复律后4至6周时收集全血样本。 将配对的样品送入基因芯片中和血浆生物标志物进行比较。

结  果

在所测试的13,942个基因中,SLC25A20和PDK4的表达与AF的相关性最强。心脏复律后,SLC25A20和PDK4表达分别下降0.8(CI 0.7-0.8,p = 2.0x10-6)和0.7(CI 0.6-0.8,p = 3.0x10-5)倍。心脏复律后,NT-proBNP浓度中位数从127.7 pg / mL降至44.9 pg / mL(p = 2.3x10-13)。与单独的NT-proBNP相比,结合型NT-proBNP和基因表达(NT-proBNP + SLC25A20曲线下面积= 0.88,NT-proBNP + PDK4AUC = 0.86)的AF辨别模型具有较高的判别能力。此外,与其他模型相比,包括NT-proBNP,SLC25A20和PDK4的模型显着提高AF辨别(AUC = 0.87,净重新分类指数> 0.56,p <5.8x10-3)。我们验证了17名患者独立样本中SLC25A20和PDK4与AF之间的关联性。

结  论

这项研究表明,SLC25A20,PDK4和NT-proBNP作为生物标志物可区分房颤与窦性心律的增量效用。AF期间SLC25A20和PDK4的表达升高表明AF中能量代谢的重要作用。
