Mock 1 · Cholesterol
Video consultation — full 12-minute exam frame, 3 minutes' reading · Long-term conditions · Prevention · Shared decision-making · Mock SCA 1 · 15:35–16:10
A 49-year-old with a QRISK of 14% has been told to take a statin, has read that they cause dementia and diabetes, and would rather 'do it naturally'.
Candidate brief
Read this as you would in the exam. Three minutes' reading, then twelve minutes. You may ask the patient for examination findings; there is no reference material.
| Patient | Elaine Marsh, 49, self-employed nutrition and wellness coach |
| Reason for appointment | "Cholesterol result — discuss" (booked after the nurse's health check) |
| PMH | Nil. Never smoked. BMI 27 |
| Medication | None. Takes omega-3, turmeric, red yeast rice (bought online). Allergies: none |
| Recent entries | NHS Health Check: total cholesterol 7.4; HDL 1.2; non-HDL 6.2; triglycerides 1.9; HbA1c 41; BP 138/86 (repeat 134/84); QRISK3 14.2%. Family history: father MI at 58 (alive after stents); paternal uncle died of MI at 52. Nurse: 'advised statin per pathway; patient declined, wants to discuss with GP' |

Persona and manner
- Articulate, confident, well-informed on her own terms; sees this as a debate she has prepared for; slightly condescending about 'the pharmaceutical model'.
- Underneath: frightened by her father's heart attack and by the number; she does not want to be told what to do, and she is genuinely open to numbers.
Opening line — say this verbatim
- "The nurse basically tried to hand me a statin prescription. I'm not against medicine, but I've read a lot about statins — the diabetes, the memory problems, the muscle damage — and I'd rather manage this naturally. I'd like to hear your honest view rather than the pathway."
Volunteer freely if given the space
- 'I eat better than anyone I know'; runs three times a week; 'no sugar'; 'red yeast rice is basically a natural statin anyway'.
- 'My dad's on five different tablets since his stents and he's never been the same.'
Only if asked
- Father: MI at 58, stents, alive, 'diminished'; uncle died at 52; grandmother 'heart' at 70. No one tested for familial hypercholesterolaemia; no known tendon xanthomata; her cholesterol 'has always been high — 6.8 five years ago'.
- No chest pain; no breathlessness; no claudication; no symptoms.
- Alcohol: wine four nights a week, 'a glass or two' — about 12 units. Sleep fine. Stress: 'a business to run'.
- Red yeast rice: two capsules a day for a year; she does not know it contains a statin-like compound (monacolin K) at an unregulated dose.
- Statins: 'I've read they cause diabetes in one in three, dementia, and everyone gets muscle pain.' She knows two clients 'who couldn't walk on them'.
- She would consider a statin 'if the numbers were compelling and it was my decision'; she would also accept 'a proper test for the family thing'.
- Menopause: perimenopausal, hot flushes, not on HRT — 'I manage it'.
Ideas, concerns and expectations
- Idea: 'diet and exercise will fix it; statins are over-prescribed'.
- Concern: her father's decline; dementia and diabetes from statins; 'being on tablets for life at 49'.
- Expectation: an honest discussion, a natural plan, and to be respected.
Cues to deliver, timed
- Minute 1: 'rather than the pathway.'
- Minute 4: 'he's never been the same' — about her father.
- Minute 8: 'if the numbers were compelling…'
How to respond to the doctor's plan
- If the doctor explores her beliefs and her father's story first, takes a family history that raises the possibility of familial hypercholesterolaemia (total cholesterol >7.5 or personal/family history of premature CHD — refer or apply Simon Broome/DLCN), explains QRISK in absolute terms she can use (14 in 100 over ten years; a statin roughly a quarter to a third fewer events — about 3–4 people per 100 helped), answers each statin belief with the evidence (new diabetes about 1 in 100 over 5 years, mostly in those already at risk; no evidence of dementia — if anything protective; muscle symptoms in trials no more common than placebo, with a nocebo effect), explains that red yeast rice is an unregulated statin, offers a genuine choice (lifestyle for three months with repeat lipids, or atorvastatin 20 mg with a 3-month check, or FH assessment first), agrees a plan with her, addresses alcohol and blood pressure, and safety-nets: she pauses — 'so the red yeast rice is a statin?' — and chooses the FH assessment with a trial of atorvastatin, 'on my terms'.
- If the doctor says 'the guideline says over 10% you should have a statin': 'that's exactly what the nurse said' — and she disengages.
- If the doctor agrees to 'natural management' without discussing FH or the numbers: she is pleased; the examiner is not.
Examination findings if requested
- BP 136/84; BMI 27; no xanthelasma; no tendon xanthomata; no corneal arcus; pulse 64.
Do not
- Volunteer the red yeast rice ingredient, the uncle's death age or the 5-year-old cholesterol unless asked.
- Concede quickly; she should be won by numbers and respect, not by authority.

Teaching points
- NICE NG238 (2023): offer atorvastatin 20 mg for primary prevention at QRISK3 ≥10%; do not rule out treatment below 10% if the person wants it; aim for >40% non-HDL reduction. Consider FH when total cholesterol >7.5 or LDL >4.9, especially with premature family CHD (NICE CG71).
- Statin harms in numbers: new diabetes about 1 extra per 100 treated over 5 years, mostly in those at risk; no causal link with dementia; muscle symptoms in blinded trials equal to placebo (SAMSON: nocebo). Red yeast rice contains monacolin K — a statin at an unknown dose.
- Statement 3.2: a well-read patient's beliefs are the consultation; the examiner watches whether you explore, quantify, then offer a choice.
