Question 2 of 5
A 48-year-old man was brought to the emergency department because of severe chest pain that had been ongoing for over 3 hours. The man had been suffering from chronic stable exertional angina for 1 year and from duodenal ulcer for 3 months. His current medication included isosorbide mononitrate and verapamil for angina and famotidine for duodenal ulcer. Which of the following events most likely triggered the patient's present chest pain?
Correct Answer: C
Rationale: The most likely trigger for the patient's present chest pain is the abrupt withdrawal from nitrate therapy. Nitrates are commonly used in the treatment of angina to help relax and widen blood vessels, improving blood flow to the heart. Abruptly stopping nitrate therapy can lead to rebound symptoms, including chest pain, due to the body's dependence on the medication for vasodilation. This withdrawal can cause a sudden decrease in nitric oxide levels, leading to vasoconstriction and potentially triggering angina symptoms.
