Body weight, ventricular weight, and echo data in sham and CHF rats

Factor	Pretreatment	Sham	CHF
n	51	24 (4 wk)	27 (4 wk)
BW, kg	2.85 ± 0.12	3.66 ± 0.10	4.08 ± 0.12
LVW/BW, g/kg		1.62 ± 0.06	2.16 ± 0.07*
LVEDD, mm	13.10 ± 0.50	13.90 ± 0.40	16.80 ± 0.40*
LVESD, mm	8.20 ± 0.30	8.40 ± 0.30	12.70 ± 0.30*
FS, %	39.70 ± 1.70	40.40 ± 1.20	21.10 ± 1.60*
EF, %	75.80 ± 1.50	75.20 ± 1.40	48.10 ± 1.90*

Values are means ± SE, where n represents number of animals. CHF, chronic heart failure; LVW/BW, ratio of left ventricular weight to body weight; LVEDD, left ventricular end-diastolic diameter; LVESD, left ventricular end-systolic diameter; FS, fractional shortening; EF, ejection fraction.
