Which Statement About Stable Angina Is True?

Which Statement About Stable Angina Is True?

• A. It Is Transient And Recurrent
• B. It Is Not Related To Coronary Blood Flow
• C. It Causes Permanent Myocyte Damage
• D. It Is Not A Transient Or Recurrent Episode

Answer: (D)

Stable angina is a pattern of transient, reproducible myocardial ischemia caused by fixed narrowing of a coronary artery. The chest discomfort lasts a few minutes, is provoked by exertion or stress, and is relieved with rest or nitroglycerin. Because the obstruction is fixed, the heart can’t sufficiently increase blood flow during activity, leading to temporary ischemia rather than lasting injury. This is why episodes are transient and recurrent rather than persistent. It does not cause permanent myocyte damage under typical stable angina, though prolonged or severe ischemia can lead to infarction in other contexts.
