the maximal inotropic effect of dopamine was about 50 % that of calcium ( 15 mm , 6.2 +/- 0.7 mn ) or ouabain ( 1 x 10 ( -7 ) m , 5.0 +/- 0.8 mn ) when measured in the same muscle strips , possibly due to the reduced cardiac noradrenaline content together with the reduced beta-receptor number in congestive heart failure .
