Should be noted total cholesterol is irrelevant if HDL is low and LDL is high. One can have an HDL fo 4, LDL of 80, still have normal total cholesterol (or even in the designated optimal bracket)… but given they’re HDL/LDL ratio, overall lack of protection from lipid oxidation etc they’re still at immense risk regarding atherogenesis.
LDL absolutely induces issues when elevated over prolonged periods of time, particle sizes, other lipid parameters (apolipoproteins) also come into play… given HDL is known as the “good”, “cardioprotective” cholesterol you’d think it’d be relevant.
If you’ve got an HDL of 65, LDL of 160, you’re HDL/LDL ratio is fine, whilst even very high levels of HDL may be linked in relation to an elevated risk regarding cardiovascular disease… the risk is minimal, and such a ratio would still elict an element of cardioprotection despite high LDL… it’s all about the ratio, particle sizes and triglycerides.
Are you sure you’re doctor said HDL/LDL doesn’t matter? That’s an incredibly ignorant and potentially dangerous thing to tell a patient (in my opinion)
If LDL wasn’t proven to cause issues, men with severe familial hypercholesterolemia wouldn’t die in their 20’s/30’s, many large meta analysis wouldn’t have come to the conclusion regarding elevated cholesterol inducing premature death
There are ways to mitigate risk even with sub-par cholesterol, a bad HDL/LDL ratio doesn’t neseccarily equate to increased lipid oxidation/plaque build up. A healthy diet, antioxidant supplementation, regular exercise can go a long way (unless you’ve got severe inherited ailment regarding cholesterol management… then see a doc, get it sorted)
