Myocardial performance index, right ventricular outflow by transesophageal, transthoracic echocardiography and invasive data.

Va1ues are mean ± SD. W = Wistar; SAD = sinoaortic denervation; SHR = spontaneously hypertensive rats; SHRSAD = spontaneously hypertensive rats with sinoaortic denervation. MPI = myocardial performance index; LV = left ventricle; RV = right ventricle; AcT = aceleration time of right ventricular outflow; TT = time from the beginning to the end of right ventricular outflow; EDPRV = end-diastolic pressure of right ventricle; EDPLV = end-diastolic pressure of left ventricle; ESPRV = end-systolic pressure of the right ventricle. ap<0.05 vs. W, bp<0.05 vs. SAD, and cp<0.05 vs. SHR.
