ΔM/M Tau (sec) T1 (sec) kf (sec−1) Normalized CK flux rate
Baseline 0.64±0.07 1.37±0.12 4.33±0.84 0.47±0.06 1
8-PT 0.62±0.07 1.17±0.14 3.28±0.37 0.58±0.14 1.13±0.26
8-PT+GLIB 0.66±0.06 1.47±0.07 4.55±0.82 0.48±0.04 0.73±0.08*

Values are means ± SE. 8-PT, 8-Phenyltheophylline at 5mg/kg intravenous; GLIB, Glibenclamide at 20 μg/kg/min intracoronary; ΔM/M, relative change of PCr resonance intensity; Tau, time constant that fits the integral of PCr magnetization decay as the time of saturation of ATPγ increased from 0 to infinite; T1, longitudinal relaxation time; kf, forward rate constant of creatine kinase;
