Stable Angina is the most common type and usually lasts

5 minutes or less More than 30 minutes Several hours A few days

Correct Answer:

5 minutes or less

Explanation:

Stable angina episodes are brief and self-limited, reflecting transient, reversible ischemia from a fixed narrowing. Because these episodes are provoked by exertion or stress and relieved by rest or nitroglycerin, they typically last five minutes or less. If chest discomfort lasts longer than several minutes or occurs at rest, it suggests an unstable pattern or evolving acute coronary syndrome that needs urgent evaluation. This short, predictable duration helps distinguish stable angina from more dangerous conditions like unstable angina or myocardial infarction.
