Vasodilators reduce systemic vascular resistance (afterload), decrease preload, relieve pulmonary congestion, and increase tissue perfusion to muscles and vital organs. Vasodilators reduce systemic vascular resistance (afterload) and reduce preload so that the high volume of blood returning to the heart is decreased.
