Why Cardiology History Taking Is High-Yield
Chest pain is the presenting complaint in roughly 5% of all A&E attendances in the UK. Cardiology history stations appear in almost every OSCE circuit — and they're often paired with a follow-up examiner question about differentials or investigations. Getting this station right is one of the highest-yield revision investments you can make.
💡 Tip
Before you start — take 10 seconds to read the station brief carefully. Note the patient's age, sex, and chief complaint. Let this guide your differential before you even walk through the door.
The Core Framework: SOCRATES + ICE
Every symptom — chest pain, palpitations, breathlessness — should be explored with SOCRATES first, then ICE.
SOCRATES Breakdown
| Letter | Question | Example phrase |
|---|---|---|
| Site | Where exactly? | "Can you point to where you feel the pain?" |
| Onset | When did it start? Sudden or gradual? | "When did you first notice this? Did it come on suddenly?" |
| Character | What does it feel like? | "How would you describe it — is it a sharp pain, a dull ache, a pressure?" |
| Radiation | Does it spread? | "Does the pain go anywhere else — your arm, your jaw, your back?" |
| Associated symptoms | What comes with it? | "When the pain is there, do you feel breathless, sweaty, or sick?" |
| Timing | Duration, constant vs intermittent | "How long does each episode last?" |
| Exacerbating/relieving | What makes it better or worse? | "Does anything bring it on — like exercise? Does rest help?" |
| Severity | 0–10 | "On a scale of 0–10, where 10 is the worst pain you've ever felt, where would you rate it?" |
ICE — Ideas, Concerns, Expectations
These three questions score marks directly and should never be skipped:
- "What do you think might be causing this?"
- "Is there anything in particular you're worried about?"
- "What were you hoping we might do for you today?"
ICE also gives the patient's agenda — an angry or worried patient will be much more co-operative once you've acknowledged what they're afraid of.
Chest Pain: Differentials and Discriminating Questions
Acute Coronary Syndrome (STEMI / NSTEMI / Unstable Angina)
💎 Clinical Pearl
Classic ACS: Central, crushing/pressure-like pain, radiating to left arm or jaw, associated with sweating, nausea, breathlessness. Brought on by exertion (stable angina) or at rest (ACS).
Key questions:
- "Does anything bring it on — exercise, climbing stairs, cold weather?"
- "Does it go to your left arm, jaw, or shoulder?"
- "Does resting or a tablet under your tongue help?" (GTN response)
- "Any sweating, feeling sick, or shortness of breath with it?"
Aortic Dissection
⚠️ Red Flag
Red flag: Sudden-onset, severe tearing or ripping pain radiating to the back between the shoulder blades. Hypertension and Marfan syndrome are major risk factors. This is a surgical emergency.
- "Did the pain come on very suddenly — like the worst pain you've ever had?"
- "Does it radiate through to your back?"
- "Do you have high blood pressure? Any connective tissue conditions?"
Pulmonary Embolism
Key questions:
- "Is the pain worse when you breathe in?" (pleuritic)
- "Any swelling or redness in your legs?"
- "Any recent long-haul flights, surgery, or periods of immobility?"
- "Do you take the contraceptive pill?"
- "Any recent illness that kept you in bed?"
Pericarditis
- "Is the pain worse lying flat and better sitting forward?"
- "Have you had a recent viral illness — cold, flu, or fever?"
Musculoskeletal / Costochondritis
- "Is it painful when I press on your chest?" (Tietze's sign)
- "Did you have a recent cough, injury, or do a lot of physical activity?"
- "Does it change with movement or posture?"
GORD / Oesophageal
- "Any acid coming back up into your throat? Any heartburn?"
- "Is it worse after meals or lying down?"
- "Does it get better with antacids?"
Palpitations — Systematic Approach
Palpitations can represent anything from benign ectopics to life-threatening arrhythmias. Ask:
- 1Onset and offset — sudden or gradual? (Sudden-on/sudden-off suggests SVT)
- 2Rate — fast or normal?
- 3Rhythm — regular or irregular? ("Can you tap it out on the table?")
- 4Duration — seconds, minutes, hours?
- 5Associated symptoms — dizziness, pre-syncope, chest pain, breathlessness?
- 6Triggers — caffeine, alcohol, stress, exercise?
- 7Thyroid symptoms — weight loss, heat intolerance, tremor?
- 8Drug history — stimulants, decongestants, inhalers?
💎 Clinical Pearl
"Can you tap out what your heart was doing?" is one of the most clinically useful questions for rhythm assessment — and it impresses examiners.
Dyspnoea — NYHA Classification
Quantify breathlessness using the New York Heart Association (NYHA) functional class:
| Class | Description |
|---|---|
| I | No limitation — ordinary activity doesn't cause breathlessness |
| II | Slight limitation — comfortable at rest, breathless with moderate exertion |
| III | Marked limitation — comfortable at rest, breathless with minimal exertion |
| IV | Symptoms at rest — unable to carry out any activity without discomfort |
Then ask about:
- Orthopnoea: "How many pillows do you sleep on? Is this more than usual?"
- Paroxysmal nocturnal dyspnoea: "Do you ever wake up in the night feeling breathless?"
- Ankle swelling: "Have your ankles been swollen at all?"
Syncope — Key Questions
Distinguishing cardiac syncope from a simple vasovagal is critical:
| Feature | Vasovagal | Cardiac | Seizure |
|---|---|---|---|
| Prodrome | Dizziness, nausea, tunnel vision | None or very brief | Aura possible |
| Trigger | Standing, heat, emotion | Exertion (dangerous), no trigger | Variable |
| Recovery | Quick, feels well after | May be slow | Prolonged confusion, headache |
| Tongue biting | No | No | Yes |
| Incontinence | Rarely | No | Yes |
Systematic Review — Never Skip These
Always ask in order (use the mnemonic DAFSHOE):
🧠 Mnemonic
DAFSHOE for systematic cardiovascular review:
- Drug history (antihypertensives, statins, anticoagulants, GTN, diuretics)
- Allergies
- Family history (first-degree relative with cardiac disease before 60)
- Social history (smoking pack-years, alcohol, occupation)
- Hypertension
- Obesity / diabetes
- Exercise tolerance (in METs or practical terms)
Red Flags — Never Miss
⚠️ Red Flag
Immediate red flags requiring urgent action:
- Chest pain at rest lasting > 20 minutes
- Radiation to jaw or left arm with sweating/nausea
- Syncope with chest pain (consider aortic stenosis or hypertrophic cardiomyopathy)
- Sudden-onset severe tearing back pain (aortic dissection)
- New arrhythmia with haemodynamic compromise
- First seizure (may be cardiac arrhythmia)
How to Close the Station
After completing your history:
- 1Briefly summarise: "So to summarise what you've told me..."
- 2Confirm accuracy: "Is that right? Have I missed anything?"
- 3ICE if not already done: "Is there anything you're particularly worried about?"
- 4Next steps: "I'd like to examine you further and arrange some tests..."
- 5Safety net: "If your symptoms get worse before we meet again, please call 999 immediately."
Common Examiner Follow-Up Questions
After the history station, examiners often ask:
- "What investigations would you request?"
- "What's your differential diagnosis in order of likelihood?"
- "What's the most dangerous diagnosis you need to rule out?"
For a chest pain station:
- First-line investigations: ECG, troponin (serial at 0h and 3h), FBC, U&E, CXR
- If PE suspected: D-dimer (Wells score) or CTPA
- If dissection suspected: CT aortogram
