Unstable angina is new, worsening, or rest angina in patients whose cardiac biomarkers do not meet criteria for myocardial infarction. Symptoms of unstable angina include new or worsening chest pain or chest pain occurring at rest. Diagnosis is based on serial ECGs and cardiac biomarkers.
Mar 22, 2024 · Unstable angina is typically severe and lasts longer than stable angina, maybe 20 minutes or longer. The pain doesn't go away with rest or the usual angina medicines. If the blood flow doesn't improve, the heart doesn't get enough oxygen.
