Which statement best describes a classic symptom of myocardial infarction?

• A. Pain is often rated 9 to 10 on a pain scale and lasts more than 30 minutes
• B. It is always relieved by nitroglycerin
• C. It is typically unrelated to exertion
• D. It is caused by a clot forming outside the coronary artery

Answer: (A)

The main idea here is recognizing what chest pain typically looks like in a heart attack. A classic myocardial infarction causes intense chest discomfort that people often describe as pressure, squeezing, or heaviness in the center of the chest. This pain is usually very severe and lasts a long time—commonly more than 20 minutes and often cited as 9 or 10 out of 10 in intensity. Because it lasts so long and isn’t reliably relieved by rest or medicines like nitroglycerin, this description fits the hallmark experience of an MI. Nitroglycerin can relieve angina but isn’t always effective for an MI, so saying the pain is always relieved by nitro isn’t accurate. Some MIs can occur with little or no exertion, but the key point is that the pain is severe and prolonged, not a short-lived or easily manageable sensation. And the cause of an MI is a blockage inside the coronary artery due to a clot forming at a ruptured atherosclerotic plaque, not a clot forming outside the artery.
