Management of Chest Pain Radiating to the Shoulder

Immediate Actions

The American College of Cardiology recommends that patients with chest pain radiating to the shoulder should receive immediate emergency department evaluation with ECG within 10 minutes, as this presentation carries a 2.3-4.7 times increased likelihood of acute coronary syndrome 1, 2
The American College of Cardiology suggests calling 9-1-1 immediately and transporting the patient by ambulance rather than private vehicle or driving to a physician's office 3
The American Heart Association recommends administering aspirin 162-325 mg orally immediately unless contraindicated or already taken 4
The European Society of Cardiology suggests giving sublingual nitroglycerin (up to 3 doses, 5 minutes apart) if previously prescribed and systolic BP >90 mmHg 3, 4, 2
The American College of Cardiology recommends initiating continuous ECG monitoring during transport to detect life-threatening arrhythmias 5, 6

The European Society of Cardiology recommends obtaining a 12-lead ECG within 10 minutes of arrival to identify ST-segment elevation ≥1 mm in contiguous leads or new left bundle branch block 5, 6, 4, 2
The American College of Cardiology suggests drawing cardiac troponin immediately with repeat measurement at 1-2 hours using rapid rule-in/rule-out protocols 1, 4, 2
The European Society of Cardiology recommends placing the patient in an environment with continuous ECG monitoring and defibrillation capability 1
The American College of Cardiology suggests not waiting for troponin results before initiating reperfusion therapy if ST-elevation is present on ECG 6, 4, 2

The American College of Cardiology recommends primary PCI as the preferred treatment if available within 90 minutes of first medical contact for patients with STEMI 4
The European Society of Cardiology suggests administering aspirin 160-325 mg if not already given, and adding a P2Y12 inhibitor (clopidogrel) for dual antiplatelet therapy 4
The American College of Cardiology recommends giving IV morphine 4-8 mg with additional 2 mg doses every 5 minutes until pain relieved (avoid IM injections) 5, 6
The European Society of Cardiology suggests administering oxygen 2-4 L/min if breathless, heart failure features, or oxygen saturation low 5, 6
The American College of Cardiology recommends starting IV nitroglycerin for ongoing chest pain unless systolic BP <90 mmHg 4, 2

The American College of Cardiology notes that elderly patients may present with atypical symptoms including generalized weakness, stroke, syncope, or altered mental status rather than typical chest pain 1, 6, 7
The European Society of Cardiology suggests that diabetic patients may have atypical presentations due to autonomic dysfunction 1, 7
The American College of Cardiology recommends considering atypical chest pain and symptoms in women 1
