Protein comparison between the left and right ventricles of each disease. A) Volcano plot of the entire set of proteins quantified in the left and right ventricles of AVS patients. B) Volcano plot of the entire set of proteins quantified in the left and right ventricles of CAD patients. Each point represents the difference in expression (log2 fold difference) between left and right ventricles plotted against the level of statistical significance. Solid lines represent ± 1.2 fold difference and a significance level of P < 0.05 (Student’s t-test). Proteins represented by (x) had less than ± 1.2 fold difference or were not statistically significant. Proteins represented by a (•) had greater than ± 1.2 fold difference and were statistically significant.
