Baseline characteristics of sham-operated and CHF rats

	Sham	CHF
Body weight, g	386.7 ± 13.5	386.7 ± 7.7
Lung weight, %body wt	0.4 ± 0.02	0.6 ± 0.07*
Infarct size, %left ventricle	0	37.9 ± 2.0*
MAP, mmHg	113.5 ± 3.3	100.4 ± 2.4
HR, beats/min	363.8 ± 12.8	317.2 ± 7.4
LVEDP, mmHg	3.9 ± 0.6	21.4 ± 2.7*
dP/dtmax, mmHg/s	8,796.7 ± 670.4	4,966.3 ± 361*
dP/dtmin, mmHg/s	−7,686.8 ± 539.4	−4,323 ± 526.1*

Values are means ± SE; n = 6 rats/group. CHF, congestive heart failure; MAP, mean arterial pressure; HR, heart rate; LVEDP, left ventricular end-diastolic pressure; dP/dt, change in pressure over change in time.

^*P < 0.05 vs. sham.
