Echocardiogram measurement to determine heart function

	Baseline	90 Days Post-MI	Baseline	90 Days Post-MI
	LVESV, ml	LVESV, ml	LVEF, %	LVEF, %
MI, n = 7	0.44 ± 0.07	0.57 ± 0.12*†	80.3 ± 1.7	74.9 ± 2.7*†
VNS-MI, n = 7	0.43 ± 0.11	0.41 ± 0.13	79 ± 4.4	81.4 ± 4.4

Values expressed as means ± SE, with number of animals shown. Significant effect (

^*P < 0.05) compared with their baseline level using repeated-measures ANOVA and significant effect (

^†P < 0.05) compared with vagus nerve stimulation (VNS)-myocardial infarction (MI). LVESV, left ventricular end systolic volume; LVEF, LV ejection fraction.
