Summary of national guidance for lipid management for primary and secondary prevention of cardiovascular disease
Check out the guidance from January 2023 ..You didn't actually include a link; and, when I search for "Summary of national guidance for lipid management for primary and secondary prevention of cardiovascular disease"-- what I get is the link I posted. Which says "Document first published 9 April 2020" and then says it was updated in December 2022 ...
I feel I should emphasise I'm not being sarcastic! If you do know of very recent research casting doubt on what NICE recommended as of late 2022, I genuinely want to know.
As it is, it looks as though you may have been looking at something out-of-date which has been overtaken by further research?
- Total cholesterol is an important predictor of CVD events. However, non-high density lipoprotein cholesterol (non-HDL-C) — the difference between total and HDL-C is a powerful risk factor.
- Non-HDL-C has replaced low-density lipoprotein cholesterol (LDL-C) as the primary target for reducing cardiovascular risk with lipid-modifying treatment.
So as of now Total minus HDL is the key measure ( no mention of 'ratios'). This January advice seems to follow the ADA/AHA revised guidance on chol measures of Dec 2022. As usual we are behind and following USA. Looks like Qrisk3 will have to be revised at least the chol measure used. HTH. The new ADA advice is also heavy on LDL targets
Mayo Clinic abandoned ratios in favour of Total minus HDL a couple of years ago.
