WebVenodilators, such as nitrates, exert a venous pooling effect, decreasing cardiac preload and symptoms of congestion. Arterial dilators, such as hydralazine, decrease afterload and improve cardiac output. The combination of hydralazine and isosorbide dinitrate provides balanced vasodilation. WebNTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen …

Cardiac Afterload: Definition & Reducing Agents

WebVasodilators are medications that open (dilate) blood vessels. They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. As a result, blood flows more easily through the vessels. The heart doesn't have to pump as hard, reducing blood pressure.
