WebMay 11, 2024 · Glyceryl trinitrate reduces the tone of vascular smooth muscle. This action is more marked on the venous capacitance vessels than the arterial vessels. There is a reduction in venous return to the heart and a lowering of elevated filling pressure. This lowering of filling pressure reduces the left ventricular end diastolic volume and preload. WebThe decrease in venous return reduces the end diastolic pressure (preload) within the left ventricle, additionally causing a decrease in systemic vascular resistance and arterial pressure (afterload) due to arteriolar relaxation (MIMS, 2024).
