PTHLH and myocardial ischemia: As expected, myocardial ischemia-reperfusion in the pig is characterized by a high incidence of VF [23]: 12/15 animals developed one or more episodes of VF during LAD occlusion or immediately upon reperfusion (n = 7 in the PTHrP(1-36)-treated group; n = 5 in controls; p = 0.57 (ns)).
