Myths About Cardiovascular Risk, Checked Against the Guidance
Cardiovascular Risk: what people commonly get wrong, set against what published UK guidance says.
Treatment decisions in the UK are made on overall risk rather than on any single number, which is why identical cholesterol can produce different advice.
Key takeaways
- Risk tool used in the UK: QRISK
- Inputs: age, sex, blood pressure, smoking, diabetes, ethnicity, family history, cholesterol
- Most useful single change: Ask what your ten-year risk score is, not just your readings.
- Commonest mistake: Focusing on one number in isolation.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
The published position, before we get to what people believe instead.
| Measure | Figure |
|---|---|
| Risk tool used in the UK | QRISK |
| Inputs | age, sex, blood pressure, smoking, diabetes, ethnicity, family history, cholesterol |
| NICE threshold to offer a statin | 10 per cent ten-year risk |
| NHS Health Check, England | ages 40-74, every 5 years |
| Largest single modifiable factor for most people | smoking |
Where people go wrong
Each of these is common, and each is a mistake in the sense that the guidance says otherwise.
- Focusing on one number in isolation
- Assuming a normal weight means low risk
- Delaying a check because you feel well; risk is silent
What to do instead
- Ask what your ten-year risk score is, not just your readings
- Accept the NHS Health Check invitation when it arrives
- Tackle smoking first if you smoke; nothing else comes close
- Treat blood pressure, cholesterol and activity as one package
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Call 999 for chest pain or tightness lasting more than a few minutes, sudden weakness or numbness on one side, facial drooping, or difficulty speaking. Use the FAST test for stroke: Face, Arms, Speech, Time to call 999. Never drive yourself to hospital.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
