Question

Quizplus · Accepted Answer

The characteristics described are typical of Prinzmetal's (variant) angina, which is caused by coronary artery spasms rather than fixed atherosclerotic lesions. It often occurs at rest, particularly at night, and can be associated with normal or near-normal coronary arteries. It is not typically precipitated by physical activity or emotional stress, as in stable or unstable angina.
