Echocardiographic parameters of WT and Tg mice in feeding or 24-h-fasting condition

	Feeding		Fasting
	WT	Tg	WT	Tg
HR, beats/min	659 ± 9	660 ± 10	603 ± 11†	608 ± 12†
FS, %	47.0 ± 1.4	46.4 ± 1.4	45.4 ± 1.7	46.7 ± 1.8
LVIDd, mm	2.94 ± 0.12	3.03 ± 0.12	2.94 ± 0.13	3.14 ± 0.12
LVIDs, mm	1.56 ± 0.09	1.59 ± 0.05	1.63 ± 0.10	1.70 ± 0.09
IVS, mm	0.78 ± 0.03	0.81 ± 0.03	0.76 ± 0.02	0.74 ± 0.02
LVPW, mm	0.71 ± 0.04	0.73 ± 0.04	0.69 ± 0.04	0.67 ± 0.02

Values are means ± SE of 9 male mice. HR, heart rate; FS, fractional shortening; LVIDd, left ventricular internal dimension in diastole; LVIDs, left ventricular internal dimension in systole; IVS, interventricular septum; LVPW, left ventricular posterior wall.
