It is considered part of the \u201cacute coronary syndrome\u201d spectrum, along with heart attack (myocardial infarction). It often presents as new, worsening, or unpredictable chest pain, sometimes occurring at rest. The term is commonly used in emergency and hospital cardiology to describe a higher-risk chest pain pattern."}
