Table 3.

Steady-state and dynamic contractile parameters measured before and following incubation with OM at equivalent levels of activator [Ca²⁺] (pCa 6.1) in control donor human heart preparations

Group	Force (mN/mm²)	P1	k_tr (s⁻¹)	k_rel (s⁻¹)	k_df (s⁻¹)
Pre-OM	6.06±1.53	0.677±0.050	0.76±0.07	56.32±4.77	0.86±0.07
Post-OM	8.56±1.87^*	0.724±0.033	0.52±0.05^*	38.26±4.32^*	0.49±0.03^*

P1: XB stiffness; k_tr: rate of force redevelopment; k_rel: rate of XB detachment; k_df: rate of XB recruitment. Paired t-tests were used to compare the data between pre- and post-OM treatment groups. 10 preparations were analyzed from 3 hearts, with multiple preparations from each heart. Values are expressed as mean ± S.E.M.

Significantly different from the corresponding pre-OM group; P < 0.05.
