Fig. 1From: Metabolomic profiling in patients undergoing Off-Pump or On-Pump coronary artery bypass surgeryHeatmap (a) showing a graphic representation of the differences in metabolite concentrations in the Off-Pump and On-Pump groups, measured at the beginning of the operation. Rows represent the metabolites and columns the samples. The Pearson distance and the average algorithm were used for the dendrogram for the metabolites on the right hand side. Panels b, c and d represent a quantitative comparison in form of a bar diagram of acylcarnitines (b), arginine (c) and glycerophospholipids (d) concentrations compared to On-Pump. # and *: p < 0.05. Data are presented as mean ± SD. a, acyl; aa, acyl-acyl; Cx:y, where x is the number of carbons in the fatty acid side chain; y is the number of double bonds in the fatty acid side chain; DC, decarboxyl; M, methyl; OH, hydroxyl; PC, phosphatidylcholineBack to article page
