Unstable angina (UA) (also "crescendo angina"; this is a form of acute coronary syndrome) is defined as angina pectoris that changes or worsens or begins suddenly at rest. [12] Unstable angina is a medical emergency and requires urgent medical treatment from a doctor. [5] It has at least one of these three features: [13]

Therefore, any disorder or disease of the coronary arteries can have a serious impact on health, possibly leading to angina, a heart attack, and even death. [3]
Among women who experience a heart attack, many do not have any prior chest pain. [19] Due to alterations in sensory pathways, diabetic and elderly individuals also may present without any chest pain and may have atypical symptoms similar to those seen in women. [8] This type of ischemia is also known as silent ischemia. [21] [22] [23] [24]
