FGF2 and aortic valve stenosis: We revealed that the FGF-2 level in AS patients compared to controls was increased (p = 0.035) (Figure 3A), but we did not find any statistically significant differences between controls and patient groups with different degrees of AS (Figure 3B), although the correlation analysis showed a weak positive relationship (p = 0.012) of FGF-2 levels regarding the AS severity degree (Figure 3C).
