Arterio-venous (coronary sinus) difference in plasma metabolomite composition measured at the beginning of the operation. Panels a and c represent the quantitative comparison of metabolites in form of a bar diagram for the corresponding heatmap (Panels b and d). Heatmap rows represent the samples and columns the metabolites. The Pearson distance and the average algorithm were used for the dendrogram for the metabolites on the top. Thus, Panels a and b represent the On-Pump group and Panels c and d represent the Off-Pump group. #: p < 0.05. Bar diagram 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, phosphatidylcholine
