Vasodilators relieve chest discomfort by improving myocardial oxygen supply, which in turn dilates epicardial and collateral vessels, improving blood supply to the ischemic myocardium.

Nitroglycerin IV (Nitro-Dur)

Nitroglycerin relaxes vascular smooth muscle via stimulation of intracellular cyclic guanosine monophosphate production, causing a decrease in blood pressure. Nitrates are useful for preload reduction and symptomatic relief but have no apparent impact on mortality rate in myocardial infarction.
