Classification
Unstable angina
Unstable angina is defined as "precordial pain at rest, which may precede a myocardial infarction".[1]
Myocardial infarction
A myocardial infarction is defined as "gross necrosis of the myocardium, as a result of interruption of the blood supply to the area".[2]
Diagnosis
The Acute Cardiac Ischemia Time-Insensitive Predictive Instrument (ACI-TIPI), a clinical prediction rule, can help diagnose patients with chest pain.[3][4]
Treatment
Clinical practice guidelines address the treatment of unstable angina and non-ST-elevation myocardial infarction.[5]
Prognosis
The Thrombolysis in Myocardial Infarction [TIMI] clinical prediction rule can predict the likelihood of morbidity in patients with unstable angina or NSTEMI.[6] The TIMI risk score is scored as one point for each of the following:
- Age 65 years or older
- At least 3 risk factors for coronary artery disease (family history or coronary heart disease, hypertension, hypercholesterolemia, diabetes, current smoking)
- Prior coronary stenosis of 50% or more
- ST-segment deviation on electrocardiogram at presentation
- At least 2 anginal events in prior 24 hours
- Use of aspirin in prior 7 days
- Elevated serum cardiac markers
