Management of Severe Chest Pain

Immediate Assessment and Management

The European Heart Journal recommends placing patients with severe chest pain on cardiac monitor immediately with emergency resuscitation equipment nearby, and performing ECG within 10 minutes of arrival 1
Obtain vital signs (blood pressure, heart rate, respiratory rate, oxygen saturation, temperature) and a focused history of the chest pain (onset, character, radiation, associated symptoms) as recommended by the European Heart Journal 2, 3
Administer aspirin 250-500mg if not contraindicated (no history of allergy or recent bleeding), as suggested by the European Heart Journal 1
Establish IV access and draw blood for cardiac biomarkers (troponin T or I), complete blood count, and basic chemistry, following the guidelines of the European Heart Journal 2
Provide supplemental oxygen if oxygen saturation is low (<94%), as recommended by the European Heart Journal 3
Administer pain relief: morphine given intravenously is the preferred drug for severe pain, titrated according to severity, according to the European Heart Journal 3

ECG interpretation is the most critical initial diagnostic tool - look for ST-segment elevation/depression, T-wave inversions, or other abnormalities, as stated by the European Heart Journal 2
Obtain chest X-ray to evaluate for pneumothorax, pneumonia, pleural effusion, or widened mediastinum, as recommended by the European Heart Journal 2
Perform bedside echocardiography if available, particularly if hemodynamic instability or new murmurs are present, following the guidelines of the European Heart Journal 2
Consider additional imaging based on clinical suspicion, such as CT angiography if aortic dissection is suspected, as suggested by the European Heart Journal 2

Recurrent ischemia (ongoing pain or dynamic ECG changes) is a high-risk feature that requires immediate intervention, according to the European Heart Journal 4
Elevated troponin levels are a high-risk feature that requires immediate intervention, as stated by the European Heart Journal 4
Hemodynamic instability (hypotension, pulmonary edema) is a high-risk feature that requires immediate intervention, following the guidelines of the European Heart Journal 4
Major arrhythmias (ventricular tachycardia, ventricular fibrillation) are a high-risk feature that requires immediate intervention, as recommended by the European Heart Journal 4
ECG showing ST-segment elevation or new left bundle branch block is a high-risk feature that requires immediate intervention, according to the European Heart Journal 2

For high-risk patients (suspected acute coronary syndrome), continue aspirin therapy, as recommended by the European Heart Journal 4
Administer low molecular weight heparin or unfractionated heparin for high-risk patients (suspected acute coronary syndrome), following the guidelines of the European Heart Journal 4
Consider beta-blockers if no contraindications (particularly with tachycardia or hypertension) for high-risk patients (suspected acute coronary syndrome), as suggested by the European Heart Journal 3
For ST-elevation MI, activate cardiac catheterization lab for primary PCI or administer thrombolytics if PCI not available within 120 minutes (door-to-needle time should be under 30 minutes), according to the European Heart Journal 2
For non-ST elevation ACS with high-risk features, plan for early invasive strategy with coronary angiography within 48 hours, as recommended by the European Heart Journal 4

Patients with ongoing chest pain should be admitted to a specialized coronary care unit or intensive care unit without delay, as stated by the European Heart Journal 2
Priority for CCU admission should be given to those with severe continuing pain, ischemic ECG changes, positive troponin test, or left ventricular failure or hemodynamic abnormalities, following the guidelines of the European Heart Journal 2

Do not rely solely on pain severity to determine urgency, as severity is a poor predictor of imminent complications such as cardiac arrest, as warned by the European Heart Journal and Praxis Medical Insights 1
Do not delay treatment while waiting for definitive diagnosis in patients with red flags, as cautioned by the European Heart Journal and Praxis Medical Insights 1
Do not discharge patients with normal ECG without further evaluation - consider serial troponin measurements (6-12 hours apart), as recommended by the European Heart Journal 4
Do not transport high-risk patients by private vehicle - approximately 1 in 300 chest pain patients transported by private vehicle goes into cardiac arrest en route, as warned by Praxis Medical Insights 1
Be aware that elderly patients or those with diabetes may present with atypical symptoms, as noted by Praxis Medical Insights 1
