Figure 4. Spearman correlation between normalised Bnp mRNA levels (using geNorm selected reference genes) in rabbit left ventricles (normal diet n = 7 and cholesterol diet n = 11) and LVDD parameters determined by echocardiography before sacrifice: transmitral flow E velocity (A), transmitral flow deceleration rate (B), mitral annulus lateral E/Em ratio (C) and mitral annulus septal E/Em ratio (D).
