Table I.

Cardiac function in each group before modeling (mean ± SD).

Groups	LVEDD (cm)	LVESD (cm)	LVEF (%)	SF (%)
Control	0.62±0.08	0.32±0.08	85.75±7.85	57.60±7.98
Sham operation	0.62±0.11	0.32±0.10	85.33±8.90	57.00±8.78
Non-medication	0.61±0.11	0.31±0.11	86.75±7.96	58.11±7.88
Medication	0.62±0.07	0.32±0.08	83.88±8.56	60.19±8.13

The remaining quantity of animals in each group: In the sham operation, 9; control, 10; non-medication, 8; and medication groups, 9. LVEDD, LVESD, LVEF and SF in each group show that P>0.05. LVEDD, left ventricular end-diastolic diameter; LVEF, left ventricular ejection fraction; LVESD, left ventricular end-systolic diameter; SF, shortening fraction; SD, standard deviation.
