Chest Pain and Panic in a 42-Year-Old With a Family History
A 42-year-old woman presents to the emergency department with 40 minutes of substernal pressure radiating to the left arm, diaphoresis, and nausea that began while she was arguing with her supervisor. She has a 6-year history of panic disorder with prior identical episodes, all of which resolved with reassurance. Risk factors: father had a myocardial infarction at 58; she smokes 1 pack per day; BMI 31; no diabetes. Vital signs: HR 112, BP 148/92, RR 22, SpO2 97% on room air. She is tearful, hyperventilating, and says "this is just my panic again - please don't do tests, I've been through this." She has no known cardiac disease and no prior ECG.
1. How do you weigh the competing explanations, and what is the risk of anchoring on her psychiatric history?
Read the worked answer
Both diagnoses can be true simultaneously, and the psychiatric label must not short-circuit the medical workup.
Features that support panic attack: young age, known panic disorder, stereotyped prior episodes, onset during acute stress, hyperventilation, tearfulness, normal oxygen saturation.
Features that raise concern for acute coronary syndrome: substernal pressure radiating to the arm, diaphoresis, nausea, tachycardia, hypertension, active smoking, obesity, family history of premature CAD. Diaphoresis and arm radiation are particularly concerning; these are not typical of panic alone.
The anchoring trap: clinicians are more likely to miss ACS in patients with known anxiety, and more likely to label women's cardiac symptoms as anxiety. Panic disorder does not protect against coronary disease - patients with panic disorder have elevated cardiovascular risk, and panic can be the presenting symptom of ischemia.
Bottom line: this presentation mandates an ECG and troponin; the psychiatric history changes the prior probability but does not lower it enough to skip testing.
2. What is your immediate diagnostic and management sequence, and how do you handle her refusal of testing?
Read the worked answer
Sequence:
- ECG within 10 minutes - non-negotiable, low burden, and can be done while talking with her.
- Troponin (high-sensitivity if available) with serial measurement per local protocol.
- Continuous cardiac monitoring, IV access, aspirin if ACS is not excluded and no contraindication.
- Targeted exam and history - ask about exertional pattern, prior stress testing, cocaine/stimulant use, and DVT risk; examine for murmurs and unequal pulses.
Handling refusal - use shared decision-making, not confrontation:
- Acknowledge her experience: "You've had these before, and I believe you. I also want to be sure we're not missing something dangerous, because the stakes of missing it are high."
- Reframe the tests as ruling out, not ruling in: "The ECG takes two minutes and lets us safely focus on your panic."
- Explain that treating panic effectively requires excluding cardiac causes; otherwise her anxiety will not resolve.
- If she still declines, document capacity and informed refusal, continue monitoring, and reassess; do not discharge with an unexplained chest pain presentation.
Judgment being tested: refusing to let a psychiatric diagnosis substitute for a cardiac workup, while preserving the therapeutic alliance.
3. Assuming cardiac workup is negative, how do you address the panic disorder at this visit and at follow-up?
Read the worked answer
At this visit:
- Deliver the reassurance explicitly and concretely ("your ECG and troponins are normal") - vague reassurance fuels future health anxiety.
- Do not start long-term anxiolytics in the ED; avoid benzodiazepines as a discharge prescription because they reinforce the "emergency pill" pattern and carry dependence risk.
- Provide a brief explanation of the panic physiology (hyperventilation → hypocapnia → paresthesias, dizziness) to reduce catastrophic misinterpretation.
At follow-up:
- Confirm she has a treating clinician and a structured plan: CBT with interoceptive exposure is first-line; SSRIs are first-line pharmacotherapy.
- Screen for depression, substance use, and suicide risk - panic disorder carries elevated suicide risk.
- Address cardiovascular risk factors (smoking cessation, weight, BP) as part of the same visit; framing them as part of anxiety care improves engagement.
- Give a written safety plan: what to do if chest pain recurs with features that differ from her usual panic (exertional onset, prolonged duration, syncope).
Judgment being tested: using the negative workup as a therapeutic tool rather than dismissing her, and avoiding the benzodiazepine shortcut.
