What is the primary action of nitroglycerin in the treatment of acute coronary syndrome?
Increasing heart rate
Dilation of blood vessels
Constriction of blood vessels
Reducing oxygen saturation in the blood
Nitroglycerin works by dilating blood vessels, which helps to improve blood flow to the heart muscle and reduce the workload on the heart. This helps alleviate chest pain associated with acute coronary syndrome. Myocardial oxygen demand is reduced by lowering preload and afterload.
