Isolated heart systolic intrinsic contractility.

Slope-Pmax−V, mmHg/μl rPmax−V Range
Sham 0.378 ± 0.073 0.94 ± 0.03
21 wk Fist 0.172 ± 0.019* 0.96 ± 0.01
21 wk Fist+lis 0.312 ± 0.065 0.97 ± 0.01
lis regression 0.133 ± 0.026*‡ 0.93 ± 0.02

Values are mean ± SD. rPmax−V Range, range of regression coefficient of the linear Pmax−V relations. For statistical purposes all age-matched control groups were combined into one group.

*

= p<0.05 compared to control;

‡

= p<0.5 compared to 21 wk Fist+lis.
