Values are means ± SE; n = 5, 6, and 6 for CON, HF, and HF-IT, respectively. CON, nonsham sedentary control; HF, aortic-banded heart failure sedentary; HF-IT, aortic-banded heart failure interval exercise trained; HR, heart rate; LVESV, left ventricular (LV) end-systolic volume; LVESP, LV end-systolic pressure; EF, ejection fraction; SV, stroke volume; ESPVR, end-systolic pressure-volume relationship; PRSW, preload recruitable stroke work; LVEDV, LV end-diastolic volume; LVEDP, LV end-diastolic pressure; EDPVR, end-diastolic pressure-volume relationship; NS, not significant.
