Biochemical composition of normal and infarcted myocardium. Collagen I content was significantly greater in infarcted myocardium than normal septum (A). Although pyridinoline crosslink content trended lower in the septum than the MI, the difference was not statistically significant (B). Pyridinoline crosslink content per collagen I content was significantly lower in infarcted myocardium than normal septum (C). Sulfated GAG content was significantly greater in infarcted myocardium than normal septum (D). Water content in MI was not significantly different than that in normal septum (E). Results plotted as mean ± standard deviation. Groups not connected by same letter are significantly different, p < 0.05 (n = 5 per group).
