Administration of nitroglycerin results in the dilation of systemic veins and decrease of myocardial wall tension and oxygen demand, accompanied by vasodilation of large- and medium-sized coronary arteries with increased coronary blood flow to the subendocardium. Nitroglycerin reduces the afterload, reduces preload coronary disease ventricular volume, and increases ventricular compliance. Click here to return to the questions
