Management of Acute Chest Pain

Initial Assessment and Triage

The American College of Cardiology recommends obtaining a 12-lead ECG within 10 minutes of arrival to identify ST-segment elevation myocardial infarction (STEMI) or other acute coronary syndromes 1
The European Society of Cardiology suggests drawing blood samples for cardiac biomarkers (troponin T or I, CK-MB mass) on admission and at 10-12 hours after symptom onset 1
Assessing vital signs, level of consciousness, and signs of hemodynamic instability (heart rate <40 or >100/min, systolic BP <100 or >200 mmHg, cold extremities) is crucial in the initial assessment 1
Evaluating for high-risk features: ongoing pain, associated symptoms (sweating, nausea, vomiting), and ECG changes is essential 1
Multi-lead ECG ischemia monitoring is recommended for continuous assessment by the European Heart Journal 2

The European Heart Journal recommends administering fast-acting aspirin (250-500 mg, chewable or water-soluble) as soon as possible for suspected ACS 1, 2
Providing pain relief with intravenous morphine titrated according to pain severity, but using caution due to potential interactions with oral antiplatelet therapy is suggested by the European Heart Journal 1, 3
Administering sublingual or intravenous nitrates for suspected myocardial ischemia or to reduce cardiac filling pressures, unless contraindicated by hypotension or bradycardia is recommended by the European Heart Journal 1, 2
Beginning heparin therapy (preferably enoxaparin) in patients with suspected ACS is recommended by the European Heart Journal 2, 3

Initiating immediate reperfusion therapy (thrombolysis or primary PCI) within 30 minutes of diagnosis is recommended by the American College of Cardiology 1
Transferring directly to cardiac catheterization laboratory if PCI facilities are available is suggested by the European Heart Journal 1, 3
If PCI is not available within 120 minutes, administering fibrinolytic therapy with weight-adjusted tenecteplase (half dose for patients >75 years old) is recommended by the European Heart Journal 3
Administering P2Y12 inhibitors: ticagrelor or prasugrel as first-line agents (if no contraindications), or clopidogrel if these are unavailable is suggested by the European Heart Journal 3

Administering aspirin, heparin, beta-blockers, and nitrates is recommended by the European Heart Journal 2
Considering early invasive strategy for high-risk patients (elevated troponin, hemodynamic instability, recurrent ischemia) is suggested by the American College of Cardiology 1, 2
Considering upstream GP2b3a inhibition for high-risk patients presenting early (<2h) after symptom onset is recommended by the European Heart Journal 3

Assessing for high-risk features: recurrent ischemia, elevated troponin levels, hemodynamic instability, major arrhythmias, and diabetes mellitus is crucial in risk stratification 1, 2
Considering admission to coronary care unit for patients with ongoing pain, ischemic ECG changes, positive troponin, left ventricular failure, or hemodynamic abnormalities is recommended by the American College of Cardiology 1
For low-to-moderate risk patients, observing for 10-12 hours after symptom onset in a chest pain unit with resuscitation capabilities and cardiac monitoring is suggested by the American College of Cardiology 1
Performing stress testing or other non-invasive testing for patients with normal initial evaluations but intermediate risk is recommended by the European Heart Journal 1, 2

Using the ADD score in the pre-hospital setting to assess likelihood of aortic dissection is recommended by the European Heart Journal 3
Focusing on pain relief and blood pressure control in suspected aortic dissection is suggested by the European Heart Journal 3
Targeting heart rate <60 beats/min and systolic blood pressure between 100-120 mmHg is recommended by the European Heart Journal 3

Considering pulmonary scintigraphy or spiral CT examination for suspected pulmonary embolism is recommended by the American College of Cardiology 1
