You Answered:

Selection ATypical angina pectoris

Incorrect

The correct answer is: (B).

If you chose "typical angina pectoris," you chose incorrectly. The patient does have anginal pain in that it is substernal, but it is somewhat atypical in that it doesn't radiate to his arms, neck, or jaw. In patients with typical exertional angina, the chest pain is closely related to exertion. Usually, the patient knows just how much exertion it takes to cause pain and tries to stay below the threshold. If the patient exercises at a time of emotional stress, after a meal, or in cold weather, the pain occurs at a lower level of exertion. The pain is typically so severe that the patient must stop all activities until it resolves.
