The nurse is caring for a patient recently diagnosed with Prinzmetal's angina. The nurse explains to the patient that with this type of angina, symptoms may be triggered by which of the following?
• Prinzmetal's angina, also known as variant angina, is characterized by cyclic chest pain that often occurs at rest (typically at night). It is caused by vasospasms, leading to narrowing of the coronary arteries.
• Vasospasms may be triggered by cold, stress, tobacco use, medications, cocaine use, and magnesium deficiency.
