In the context of treating acute pain associated with suspected myocardial infarction, nitroglycerin is used primarily to alleviate chest pain. It acts as a vasodilator, relaxing the smooth muscles of the coronary arteries, which increases blood flow to the myocardium. This can help reduce ischemic pain that occurs during a myocardial infarction by improving oxygen delivery to the heart muscle.

For patients experiencing severe chest pain, nitroglycerin can relieve discomfort rapidly by decreasing the workload on the heart and dilating blood vessels, thereby lowering the oxygen demand of the heart. While other medications like aspirin are important in the overall management of myocardial infarction by helping to inhibit platelet aggregation, nitroglycerin's specific action on pain relief during an acute event makes it particularly relevant for treating the symptoms of myocardial ischemia.

Other medications like ibuprofen provide analgesic effects but are not typically indicated for myocardial infarction, as the treatment focus is on coronary artery perfusion and rapid symptom relief. In this acute scenario, morphine may also be used to manage severe pain, but nitroglycerin is specifically recognized for its immediate effects on chest pain management in myocardial infarction cases.
