Unstable angina is a type of chest pain that is unexpected and usually occurs while resting. It is caused by reduced blood flow to the heart muscle because the coronary arteries are narrowed by fatty buildups (atherosclerosis) that can rupture, causing injury to the coronary blood vessel. Unstable angina should be treated as an emergency.
The diagnosis of unstable angina is made based on the presence of symptoms suggestive of myocardial ischemia (e.g., acute chest pain), ECG findings, and the result of troponin testing. A resting 12-lead ECG should be recorded and interpreted within 10 minutes of the point of first medical contact in any patient with suspected unstable angina. In practice, a diagnosis of unstable angina should be made by a cardiologist; the diagnosis is confirmed using further diagnostic imaging, which includes invasive coronary angiography, functional (stress) testing, or coronary computed tomography angiography.
