Regional myocardial work during the different interventions. (a) Representative LV pressure-strain loops from a segment in the anterior, apical LV region for the different interventions in one animal. (b) Median regional work for all animals during the different interventions: baseline (BAS), ischemia (ISC), dobutamine (DOB), and dobutamine + ischemia (DOB + ISC). Black triangles represent mean values.
