Nitroglycerin works mostly by causing venous dilation, which decreases preload, decreasing the amount of work of the heart. Nitroglycerin also causes a small amount of coronary vessel dilation. Nitroglycerin has a proven role in AMI. It is less well documented on its effects in angina, but at this point it is considered the standard of care.

There may be more than one correct answer for this decision point.
