PY - 2023 T2 - Current Medical Diagnosis & Treatment 2023 AB - ESSENTIALS OF DIAGNOSISSudden but not instantaneous development of prolonged (> 30 minutes) anterior chest discomfort (sometimes felt as “gas” or pressure).Sometimes painless, masquerading as acute heart failure, syncope, stroke, or shock.ECG: ST-segment elevation or left bundle branch block.Immediate reperfusion treatment is warranted.Primary PCI within 90 minutes of first medical contact is the goal and is superior to fibrinolytic therapy.Fibrinolytic therapy within 30 minutes of hospital presentation is the goal and reduces mortality if given within 12 hours of onset of symptoms.
