left ventricular filling pressures declined similarly with both captopril ( -10.5 mm hg ) and with isosorbide dinitrate ( -9.3 mm hg ) , but because pulmonary arteriolar resistance fell significantly with nitrate therapy , mean right atrial pressure decreased more with isosorbide dinitrate than with captopril ( -5.4 vs -2.8 mm hg , respectively ; p less than 0.001 ) .
