Experimental Autoimmune Myocarditis (EAM)

The Experimental Autoimmune Myocarditis (EAM) Model mimics human myocarditis. Myocarditis results from inflammatory cell infiltration and myocardial injury leading to cardiac dilation and dysfunction.

Experimental Protocol

Experimental autoimmune myocarditis is induced via vaccination with myosin heavy chain (MHC) emulsified in Complete Freund’s adjuvant (CFA). Cardiac remodeling is monitored using echocardiography at 14 days post-injection. Final samples and measurements are collected.

Abbreviations: IVSd, Interventricular Septum Thickness at end Diastole; LVEDd, Left-Ventricular End-Diastolic Dimension; LVPTd, Left-Ventricle Posterior Wall Thickness Diastole; IVSs, Interventricular Septum Thickness at end Systole; LVESd, Left-Ventricular End-Systolic Dimension; LVPTs, Left-Ventricle Posterior Wall Thickness Systole; HR, Heart Rate; FS, Fractional Shortening; EF, Ejection Fraction. All parameters are expressed as means ± the SD. The P value was calculated by comparing the final echo of the SHAM and EAM mice.
