although systemic resistance declined similarly with both drugs , cardiac index increased more with nitrate therapy than during converting-enzyme inhibition ( +0.47 vs +0.23 l/min/m2 ) ( p less than 0.01 ) , and therefore mean arterial pressure fell less with isosorbide dinitrate than with captopril ( -10.5 mm hg vs -16.7 mm hg ) ;
