Quizplus · Accepted Answer

Unstable angina is characterized by worsening symptoms and is often a warning sign of an impending heart attack. It is caused by a ruptured or eroded plaque in the coronary arteries and is a medical emergency. Stable angina, on the other hand, is predictable and does not indicate an immediate threat of a heart attack.
