Which statement is most characteristic of myocardial infarction pain?

Explanation:
Prolonged chest pain lasting thirty minutes or more is the hallmark feature that points toward myocardial infarction. Ischemic pain from an MI tends to be a heavy, pressure-like sensation that persists well beyond a few minutes, unlike angina or other chest pains that are brief and often relieved by rest or nitroglycerin. Pain relieved by antacids suggests a GI origin such as reflux, and pain that changes with breathing points to pleuritic or musculoskeletal causes. Therefore, the enduring nature of the discomfort—lasting over 30 minutes—best matches an MI.
