Morphological and hemodynamic characteristics of Sham and CHF groups

	Sham (n = 10)	CHF (n = 10)
Infarct size, % of left ventricle	0	36 ± 0.02*
LVEDP, mmHg	3 ± 0.5	26 ± 2.8*
dP/dt max, mmHg/s	8,291 ± 443	6,936 ± 291*
dP/dt min, mmHg/s	−9504 ± 697	−6157 ± 416*
MAP, mmHg	112 ± 8.3	107 ± 4.0
HR, beats/min	348 ± 8.3	347 ± 7.2
EF, %	69 ± 0.9	41 ± 2.7*
FS, %	40 ± 0.7	2.1 ± 1.7*

Data are represented as means ± SE. CHF, chronic heart failure; LVEDP, left ventricular end-diastolic pressure; dP/dt, delta pressure divided by delta time; EF, ejection fraction; FS, fractional shortening; MAP, mean arterial pressure; HR, heart rate.
