SHAM: rats subjected to surgery but without coronary occlusion; BW: body weight; HR: heart rate; LVWT: LV posterior wall thickness; LVEDD: LV end-diastolic dimension; LVESD: LV end-systolic dimension; LA: left atrium; RWT: relative wall thickness; E wave: peak velocity of transmitral flow during early ventricular filling; A wave: peak velocity of transmitral flow during atrial contraction; IVRT/RR0.5: isovolumetric relaxation time corrected for heart rate; EDT: E wave deceleration time; PWSV: posterior wall shortening velocity; FAC: fractional area change. Data are expressed as means±SD or medians (25%-75%).
