Values are presented as mean with standard deviation. SD indicates Sprague-Dawley; LV, left ventricle; BW, body weight; LVEDP, left ventricular end-diastolic pressure; ANP, atrial natriuretic peptide and BNP, B-type natriuretic peptide. dP/dtmax represents the maximum rise in LV pressure in early systole corrected for peak systolic pressure.
