Characteristics of sham and CHF rats

	Sham	CHF
Body weight, g	386 ± 16	431 ± 24*
Heart weight, g	1.3 ± 0.2	1.7 ± 0.2*
Wet lung weight, g	1.8 ± 0.1	2.1 ± 0.2*
Infarct size, % of epicardial LV	0	34 ± 6*
LVEDP, mmHg	1 ± 1	20 ± 4*
+dP/dtmax, mmHg/s	7,538 ± 385	5,827 ± 319*
−dP/dtmax, mmHg/s	−5,328 ± 641	−4,082 ± 281*

Values are means ± SE; n = 15 for each group of sham-operated (Sham) and chronic heart failure (CHF) rats.

LV, left ventricle; LVEDP, left ventricular end-diastolic pressure; ±dP/dt_max, maximum rate of rise and fall in pressure over time.

^*P < 0.05 compared with respective sham group.
