Scenario

John Mitchell, a 72-year-old retired accountant, presents with palpitations and fatigue for the past 3 months.

He describes occasional shortness of breath on exertion but no chest pain or syncope.

He has a history of hypertension (on perindopril) and a family history of stroke.

He is worried about whether he has a heart condition and wants to know about treatment options.

On examination:

  • BP: 138/86 mmHg
  • HR: Irregularly irregular, 96 bpm
  • Heart sounds: No murmurs, normal S1/S2
  • Lungs: Clear
  • No peripheral oedema

ECG Findings:

  • Irregularly irregular rhythm, absent P waves, fibrillatory baseline – consistent with atrial fibrillation.

Likely Diagnosis:

Newly diagnosed atrial fibrillation (likely persistent).

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: How would you explain John’s diagnosis and its implications?

The competent candidate should:

  • Explain atrial fibrillation (AF) in simple terms:
    • “AF is a condition where the heart beats irregularly and sometimes faster than normal due to abnormal electrical activity.”
    • “It can lead to symptoms like palpitations, fatigue, and breathlessness, and increases the risk of stroke.”
  • Stroke risk:
    • Blood can pool in the heart, forming clots that may travel to the brain and cause a stroke.
    • The risk is assessed using the CHA₂DS₂-VASc score.
  • Reassurance and treatment options:
    • “AF is common and manageable with medications and lifestyle changes.”
    • “We will assess whether you need medication to slow the heart rate, restore normal rhythm, or reduce stroke risk.”

Q2: What further investigations are needed to assess John’s condition?

The competent candidate should:

  • Baseline cardiovascular and metabolic tests:
    • ECG (to confirm AF and assess for rate, QRS, QT abnormalities).
    • Echocardiogram (to check for structural heart disease or thrombus).
    • 24-hour Holter monitor (if paroxysmal AF is suspected).
    • Thyroid function tests (TSH, T4) (to exclude hyperthyroidism).
    • FBC, U&E, LFTs (to check for anaemia, electrolyte imbalances, and liver function).
  • Stroke risk assessment:
    • CHA₂DS₂-VASc score to determine anticoagulation need.
  • Bleeding risk assessment:
    • HAS-BLED score to evaluate anticoagulation safety.

Q3: What are the key components of John’s management plan?

The competent candidate should:

  • Rate vs rhythm control:
    • Rate control preferred (e.g., beta-blockers or calcium channel blockers) unless symptomatic despite rate control.
    • Rhythm control (cardioversion or antiarrhythmics) considered if AF is new onset (<48 hours) or significantly impacting quality of life.
  • Anticoagulation for stroke prevention (based on CHA₂DS₂-VASc score):
    • Warfarin or NOACs (e.g., apixaban, rivaroxaban) if high stroke risk.
    • Discuss risks/benefits of anticoagulation based on HAS-BLED score.
  • Blood pressure control:
    • Ensure BP is well controlled to reduce AF progression and stroke risk.

Q4: How would you educate John on lifestyle modifications and risk reduction?

The competent candidate should:

  • Lifestyle modifications to reduce AF triggers:
    • Regular physical activity (moderate-intensity, avoiding excessive exertion).
    • Limit caffeine and alcohol intake (excess alcohol can trigger AF).
    • Maintain a healthy weight (obesity is a key AF risk factor).
    • Manage stress and sleep disorders (e.g., screen for sleep apnoea).
  • Regular monitoring and follow-up:
    • Annual cardiovascular risk review.
    • Blood tests every 6-12 months if on anticoagulation.

Q5: When would you consider referral to a cardiologist?

The competent candidate should:

  • Urgent referral if:
    • Severe symptoms (syncope, unstable BP, severe breathlessness).
    • Uncontrolled heart rate despite medication (>110 bpm).
  • Routine cardiology referral if:
    • Rhythm control (e.g., electrical or pharmacological cardioversion) is being considered.
    • High stroke risk requiring left atrial appendage closure (if anticoagulation contraindicated).

SUMMARY OF A COMPETENT ANSWER

  • Explains AF in a patient-friendly way, addressing stroke risk and symptoms.
  • Orders appropriate investigations, including ECG, echocardiogram, and CHA₂DS₂-VASc scoring.
  • Develops a structured management plan, including rate control, anticoagulation, and lifestyle changes.
  • Provides clear guidance on monitoring, follow-up, and when to seek urgent care.
  • Recognises when referral to a cardiologist is required.

PITFALLS

  • Failing to assess stroke risk with CHA₂DS₂-VASc score.
  • Not discussing anticoagulation or misjudging bleeding risk.
  • Overlooking modifiable risk factors such as weight, alcohol, or sleep apnoea.
  • Not considering referral when symptoms are severe or persistent.
