Va1ues are mean ± SD.W = Wistar; SAD = sinoaortic denervation; GSHR = spontaneously hypertensive rats; GSHRDSA = spontaneously hypertensive rats with denervation;LVd = left ventricular end-diastolic dimension; LVd = left ventricular end-systolic dimension; IVSd = interventricular septum thickness in diastole; PWd = posterior wall thickness in diastole; FS = fractional shortening; CI = cardiac index; LVMass = left ventricular mass; RWT = relative wall thickness; Ao = aortic dimension; LA = left atrium thickness in diastole.apbp
