mPer2-M mice showed improved LV pressure, end-systolic pressure-volume relationship (ESPVR), and preload recruitable stroke work (PRSW) 4 days after infarction. ESPVR: slope of the best fit line through the end-systolic pressure-volume points in the series of pressure-volume loops. With linear fit, all slopes have regressions r > 0.94. PRSW: r > 0.95 for each of the stroke work/end-diastolic volume slopes.
