Chest Pain
Chest pain in the urgent care setting: the disposition question is binary — ED or not. ECG within 10 minutes of any concerning chest pain. Most outpatient settings cannot definitively rule out ACS — when in doubt, send. This page covers can't-miss diagnoses (ACS, aortic dissection, PE, pneumonia, pneumothorax, pericarditis, esophageal rupture, sepsis, arrhythmia, severe anemia), red flags, immediate management while you work it up, condition-specific pathways, the minimum safe first-pass workup, what can be managed outpatient only after serious causes are excluded, escalation criteria, defensive documentation, and safety-net return precautions. Written for NPs, PAs, and MDs caring for all adults — with a geriatric-modifier section at the bottom for adults 55+, geriatrics 65+, and frail younger adults.

Chest Pain
Why this symptom matters
The disposition question is binary: ED or not. ECG within 10 minutes of any concerning chest pain. Most outpatient settings cannot definitively rule out ACS — when in doubt, send.
Treat any chest-pain equivalent (dyspnea, sudden weakness, diaphoresis, nausea, syncope, "just not feeling well") with the same urgency as chest pain itself, especially in patients with cardiac risk factors.
What must I not miss first?
- Acute coronary syndrome (STEMI / NSTEMI / unstable angina)
- Aortic dissection
- Pulmonary embolism
- Pneumonia
- Pneumothorax
- Pericarditis (with or without tamponade)
- Esophageal rupture
- Sepsis
- Arrhythmia
- Severe anemia
Red flags — escalate or work up urgently
- Pressure-like pain radiating to arm/jaw/back, with diaphoresis or nausea
- Chest pain + shortness of breath
- Chest pain + syncope or near-syncope
- Chest pain + new confusion (geriatric MI equivalent)
- Hypotension, tachycardia, or new murmur
- SpO₂ < 92%
- Sudden tearing pain to back; unequal pulses or BP differential between arms
- Pleuritic pain + tachycardia + hypoxia + recent immobility/surgery (PE)
- Sudden unilateral pleuritic pain with decreased breath sounds (pneumothorax)
- Unilateral leg swelling
- Anticoagulated patient with new severe pain
- Any new EKG finding
Immediate Management — While You Work It Up
- Vitals + SpO₂ immediately. Place on continuous monitoring.
- 12-lead ECG within 10 minutes — non-negotiable for any concerning chest pain or chest-pain equivalent in an older adult.
- Check blood glucose — hypoglycemia and DKA can mimic or coexist.
- Aspirin 325 mg PO (chewed) — give immediately if ACS not excluded. Hold for true allergy or active GI bleed.
- IV access and continuous cardiac monitoring.
- Nitroglycerin 0.4 mg SL — may repeat q5 min × 3. Hold if SBP < 90, HR < 50 or > 100, suspected inferior MI, or sildenafil/tadalafil within 24–48 h.
- Oxygen only if SpO₂ < 90% — routine O₂ in normoxic patients is not recommended (AHA).
- Avoid NSAIDs — can worsen ACS and renal function in older adults.
- Avoid GI cocktails until ACS is ruled out — symptomatic relief can falsely reassure.
- NPO if escalation to ED is likely. Patient should not ambulate unassisted.
- If ACS suspected → ED immediately.
Minimum safe first-pass workup
- What to ask: onset, character, radiation, exertional component, prior similar episodes, recent immobility/surgery, anticoagulation, illicit drug use, baseline functional status
- What to examine: vitals + SpO₂, equal breath sounds, equal pulses bilaterally, JVP, lung exam, abdominal/leg exam (DVT)
- 12-lead ECG within 10 minutes — repeat in 15–30 min if first is non-diagnostic and pain ongoing
- POC troponin if available (a single negative does not exclude ACS)
- CXR if pulmonary cause suspected
- CBC, BMP
- Wells/PERC before any D-dimer
- Blood glucose
What can usually be managed outpatient
Only after ACS, PE, dissection, and pneumonia have been thoughtfully ruled out:
- Reproducible musculoskeletal chest-wall pain in well-appearing patient with normal exam and ECG
- Stable known GERD with classic features
- Costochondritis with normal vitals and benign exam
- Stable angina with established cardiology plan, symptoms unchanged
- Anxiety-related chest pain (diagnosis of exclusion in adults 55+)
When to escalate to ED / higher level of care
Condition-specific pathways:
- Suspected ACS: ECG, vitals, ASA, O₂ if hypoxic, ED transfer immediately. Avoid delays.
- Suspected aortic dissection: sudden tearing pain, pulse deficits, neurologic symptoms → ED immediately.
- Suspected PE: tachycardia, hypoxia, unilateral leg swelling, recent surgery → ED immediately.
- Suspected pneumonia: CXR, CBC, consider empiric antibiotics; ED if unstable.
- Suspected GI cause (after ACS ruled out): GERD, esophageal spasm, gallbladder disease, pancreatitis.
Escalate to ED for:
- Any red flag
- Any concerning ECG change, ST shift, new BBB, or new arrhythmia
- Elevated troponin
- Hypoxia, hypotension, or new confusion
- Persistent or progressive pain despite NTG / antacid trial
- Suspected ACS, PE, dissection, pneumothorax, or perforation
- Older adult, diabetic, or anticoagulated with atypical pain you cannot fully explain
- No improvement with initial treatment
- Inability to obtain ECG/troponin in a timely manner
What to document when the diagnosis is still uncertain
- Exact pain description, onset, duration, triggers, radiation, associated symptoms
- Vitals + SpO₂ (initial and serial)
- EKG findings (or absence of changes)
- CXR findings, labs ordered
- "ACS / PE / dissection considered and ruled out today because…"
- Why ED transfer is or is not indicated
- Discharge vitals, specific safety-net instructions, follow-up plan
- Who was notified (PCP, cardiology, family)
Safety-net & return precautions to give
- Call 911 / go to the ED for chest pain that returns, worsens, lasts > 15 min, or comes with sweating, nausea, jaw/arm/back pain, shortness of breath, fainting, or palpitations.
- Return today for new fever, leg swelling, vomiting, new confusion, or coughing up blood.
- Return if no improvement in 24 hours.
- Follow up in 24–72 hours regardless of symptoms.
Geriatric-specific modifiers (apply on top of the above)
The guidance above applies to all adult patients seen in this setting. Layer the points below for adults 55+, geriatric (65+), and frail younger adults — they are additions, not replacements.
Chest pain in older adults is high-risk because classic symptoms of cardiac ischemia are often absent. Older patients may present with shortness of breath, fatigue, weakness, nausea, confusion, syncope, or "just not feeling well."
Up to 40% of older adults with MI have no chest pain. Treat chest-pain equivalents the same way you would treat chest pain itself.
- Lower your threshold for ECG and troponin in any vague decompensation in adults 55+ or frail patients.
- Consider silent ischemia in diabetics, women, and patients with dementia who cannot describe pain.
- Confusion or new functional decline can be the only presenting feature of ACS — work it up.
- Beta-blockers, rate-control meds, and pacemakers can blunt the tachycardic response — do not use a "normal" HR to reassure yourself.
