The study of small-molecule metabolites may assist in cardiovascular risk monitoring during therapy. We assessed whether acute changes in the metabolome by lipoprotein apheresis are able to predict changes in microvascular function. We performed mass-spectrometry-based profiling of 186 metabolites in
