we compared the acute hemodynamic effects ( by swan-ganz catheterization ) and long-term responses ( maximal oxygen uptake during exercise ) associated with isosorbide dinitrate , a predominant venodilator , captopril , an arterial and venous dilator , and minoxidil , an arterial dilator , in 22 patients with congestive heart failure .
