Unstable Angina

Unstable angina is a type of chest pain that occurs unexpectedly and often lasts longer than stable angina, which typically happens with exertion and goes away with rest. It can occur at rest, during minimal activity, or with increased intensity. This condition indicates that the heart is not getting enough oxygen due to narrowed arteries, and it may signal a higher risk of a heart attack. Symptoms can include chest discomfort, shortness of breath, and fatigue. Unstable angina is a medical emergency and requires immediate attention to prevent serious complications.
