Nitroglycerin mechanism of action preload

WebThese actions produce a reduction in both preload and afterload, with significant reduction of the left ventricular volume and wall tension, and, therefore, a reduction in the myocardial demand for oxygen. , In patients with coronary arterial disease and elevated left ventricular end-diastolic pressure, therapy with nitroglycerin seldom causes an … WebAt low doses, nitroglycerin dilates veins more than arteries, thereby reducing preload (volume of blood in the heart after filling); this is thought to be its primary mechanism of action. By decreasing preload, the heart has less blood to pump, which decreases oxygen requirement since the heart does not have to work as hard.
