the present study examined the regional vascular effects ( radioactive microspheres ) of converting-enzyme inhibition ( captopril , 1 mg/kg ) and calcium-antagonism ( diltiazem , 1 mg/kg ) in a rat model of cardiac failure due to large myocardial infarction ( n = 18 , infarct size 40 % of the left ventricle ) both at rest and during submaximal treadmill exercise .
