in excised cross-circulated dog hearts , a decrease in cp from 82 ( mean ) to 51 mmhg decreased ventricular contractility index emax ( slope of end-systolic pv relation ) by 17 % ( p less than 0.05 ) and slightly ( p less than 0.05 in 3 of 11 hearts ) lowered the vo2-pva relation in a parallel fashion .
