Table 2.

Comparison of the duration of the anesthetic-surgical procedure and the percentage of rats with ejection fraction of the left ventricle (LVEF) less than 40% between G1, G2 and SHAM groups.

Number of Operated Rats	Duration in minutes of the anaesthesia and surgery (mean ± standard deviation)	Number of surviving rats 24 hours after surgery	Mortality Rate (%)	Number (%) of surviving rats whose LVEF <40%
G1: n=35	14.6±0.1^a	16	54.3^a	56.3^a
G2: n=40	5.5±0.2^b	20	50.0^a	30^ab
SHAM: n=14	-	14	0^b	0^b

n=sample size; different letters between rows = P<0.05, and is the significance of the difference between the groups
