despite the fact that beta receptor density was decreased by 50 % in failing hearts ( iodocyanopindolol bmax 84.4 +/- 8.9 fmol/mg protein in nonfailing hearts vs 42.9 +/- 3.2 fmol/mg in failing hearts , p less than 0.01 ) , dihydropyridine calcium antagonist binding sites were not reduced significantly by heart failure .
