Echocardiographic assessment of the left ventricular chamber

Genotype	LVEDD, cm	LVESD, cm	FS
Wild type	0.237	0.081	0.66
α-MHC-hMCIP1	0.253	0.098	0.62
α-MHC-CnA*	0.479	0.339	0.30
α-MHC-CnA* × α-MHC-hMCIP1	0.298	0.113	0.63

Data collected from 20-week-old male littermates. LVEDD, left ventricular end-diastolic dimension; LVESD, left ventricular end-systolic dimension; FS, fractional shortening; FS = (LVEDD − LVESD)/LVEDD.
