Comparison of LV chamber dimension and fraction shortening (FS) in sham-operated (Sham), myocardial infarction-induced (MI), sham-operated and treated with H₂S (Sham+H₂S), and myocardial infarction-induced and treated with H₂S (MI+H₂S) mice.

Experimental groups	Sham	Sham+H2S	MI	MI+ H2S
FS,%	64±0.4	65±0.8	28±0.4*	47±0.3*#
LVDd, mm	2.17±0.5	2.16±0.3	3.2±0.5*	2.85±0.5*#
LVDs, mm	0.87±0.2	0.98±0.5	2.15±0.4*	1.6±0.9*#

Presented results are calculated from the following equation [(LVDd−LVDs)/LVDd] ×100%.

* P < 0.05 vs. Sham and Sham+H₂S, # P<0.05 vs. MI; n=9 for all groups.
