measurements and main results : glyceryl trinitrate infusion ( 18 micrograms.kg-1.min-1 ) in rats with congestive heart failure caused by a 28.5 ( sem 3.5 ) % infarction induced a rapid fall in left ventricular end diastolic pressure from 12.0 ( 0.8 ) mm hg to a peak effect of 5.5 ( 0.6 ) mm hg within 30 min ( n = 7 ) , but rapid attenuation developed beginning about 4 h after the start of the infusion .
