FGF23 and myocardial infarction: In the setting of experimental myocardial infarction in mice, Andhrukova et al. [32] found that circulating FGF23 levels were increased with a concomitant reduction in the level of 1,25(OH)2-vitamin D3 and that myocardial FGF23 mRNA and protein levels were increased, suggesting that the observed increase in circulating FGF23 levels after myocardial infarction was at least partially derived from the myocardium itself [31].
