Disclosed herein are compositions and methods for targeted metabolomics profiling to provide absolute quantification of a broad array of metabolic intermediates of fatty acids, amino acids, and carbohydrate metabolism for HFpEF. In an aspect, the disclosure relates to a method for assessing risk of death or a major adverse cardiac event (MACE) in a subject diagnosed with heart failure with preserved ejection fraction (HFpEF). The method may include (a) determining in a sample from the subject the level of each metabolite in at least one factor, wherein the factor is selected from the group consisting of factor 1, factor 3, factor 4, factor 5, factor 10, factor 12, and factor 14; and (b) comparing the level of each metabolite in the sample to a standard, wherein the level of the metabolite in the subject relative to a standard is indicative of the risk of death or MACE in the subject.
本文公开了用于靶向代谢组学分析的组合物和方法,以提供针对 HFpEF 的脂肪酸、氨基酸和碳水化合物代谢的一系列代谢中间产物的绝对定量。在一个方面,本公开涉及一种用于评估被诊断为射血分数保留型心力衰竭(HFpEF)的受试者死亡或重大心脏不良事件(MACE)风险的方法。该方法可包括(a)在受试者的样本中确定至少一种因子中每种代谢物的水平,其中因子选自由因子1、因子3、因子4、因子5、因子10、因子12和因子14组成的组;以及(b)将样本中每种代谢物的水平与标准进行比较,其中受试者体内代谢物相对于标准的水平指示受试者的死亡或MACE风险。
