The predominant venodilation results in decreased venous return to the heart by reducing the left ventricular end-diastolic volume, left ventricular end-diastolic pressure(preload), and the ventricular wall tension,therebyindirectly facilitating subendocardial blood flow. Isosorbide dinitrate also comes as an injection or drip (infusion), which is given in hospital. Long-acting nitrates.
