Values are expressed as mean ± SEM. MI mice were randomized to one of six experimental groups.

HW, heart weight; BW, body weight. LVEF, left ventricular ejection fraction; LVFS, left ventricular fractional shortening; LVIDd, left ventricular internal diameter at end-diastole; LVIDs, left ventricular internal diameter at end-systole. Baseline, at the beginning of the normal model construction prior to the operation in the studied mice; BK, bradykinin; PC, preconditioning; HOE, HOE140; LY, LY294002; LN, L-NAME. ^* P < 0.01 vs. Baseline, Sham, and Con group, ^# P < 0.01 vs. EPCs group. n = 5 - 6 for each group.
