A key symptom of coronary ischemia is chest pain or pressure, known as angina pectoris. [4] Angina may present typically with classic symptoms or atypically with symptoms less often associated with heart disease. [19] Atypical presentations are more common in women, diabetics, and elderly individuals. [8] Angina may be stable or unstable.
Symptoms of unstable angina are the same as those of stable angina, however the pattern of the symptoms changes. [7] In unstable angina, symptoms related to decreased blood flow to the heart may appear on rest or on minimal exertion. [4] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get ...

[6] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get worse over time. [8] [10] Though ACS is usually associated with coronary thrombosis, it can also be associated with cocaine use. [11]
The diagnosis of microvascular angina (previously known as cardiac syndrome X – the rare coronary artery disease that is more common in females, as mentioned, is a diagnosis of exclusion. Therefore, usually, the same tests are used as in any person suspected of having coronary artery disease: [ 77 ]
It is named for Samuel A. Levine (1891–1966), an influential American cardiologist, who first observed that many patients with chest pain made this same sign to describe their symptoms. This clenched fist signal may be seen in patients with acute coronary syndrome (myocardial infarction and angina pectoris). [citation needed]
