Echocardiography results in control and HF rabbits.

Parameter	Control (n=6)	HF (n=6)	P-value
LVEF (%)	77.8±2.3	39.2±2.5	<0.001
LVIDd (cm)	1.4±0.1	1.2±0.1	<0.001
LVIDs (cm)	0.8±0.1	0.9±0.1	0.009
FS (%)	53±3	26±2	<0.001
LA diameter (mm)	7.0±0.6	8.3±0.8	0.008

Values are expressed as the mean ± standard error of the mean. HF, heart failure; LVEF, left ventricular ejection fraction; LVIDd, left ventricular internal diameter end diastole; LVIDs, left ventricular internal diameter end systole; FS, fractional shortening; LA, left atrial.
