A 48‑year‑old female patient reports to the emergency room experiencing episodes of severe chest pain that often occur at rest, sometimes waking her from sleep. The ECG obtained during an episode shows transient ST‑segment elevation, but the pain resolves quickly with nitroglycerin. The patient was diagnosed with Prinzmetal angina. The patient asks the nurse, “How is this different from having a heart attack?” Which explanation should the nurse give?
