Reduction of contractile performance in the myocardium from unilaterally nephrectomized rats.
The contractile performance of left ventricle papillary muscles from sham operated controls and uninephrectomized rats was investigated using isometric contractions. The results suggest that unilateral nephrectomy induces a decrease in the developed tension of the papillary muscles characterizing a reduction in contractility.
