Two people can have the exact same LDL and very different risk of a heart attack.
One of the most controversial topics in medicine is cholesterol and statins, which effectively lower LDL (“bad” cholesterol). Organizations like the American College of Cardiology and American Heart Association recommend lowering LDL to less than 70 mg/dL for primary prevention of ASCVD (atherosclerotic cardiovascular disease) for people whose 10-year risk is 10% or higher. This might make sense for some people.
The “lower LDL is always better” argument has become more of a slogan than a conclusion — repeated so often that questioning it gets treated like heresy instead of normal scientific inquiry.
Dr. Nick Norwitz, a physician-researcher (Oxford PhD, Harvard MD), wrote a piece worth reading on this: “When Cholesterol Science Becomes Religion”. He uses a real case — a 55-year-old woman whose LDL is already 75 mg/dL — to ask whether pushing an already-low number even lower reliably helps her, or whether we’re reciting a rule instead of looking at her actual evidence. I agree with where he lands.
Here is a link to his article on substack:

My take: LDL matters, but it was never the whole story. Dr. Benjamin Bikman makes a similar case in Why We Get Sick — he argues insulin resistance may be the single most relevant variable in heart disease, more than any one lipid number. One practical example from his work: your triglyceride-to-HDL ratio (just divide the two numbers off your last lipid panel) is a strong proxy for LDL particle size. A low ratio (under ~2.0) skews toward larger, more buoyant LDL particles — generally less atherogenic. A high ratio means more small, dense particles, which pe*****te the artery wall more easily. Two people with identical LDL can have very different real risk based on this ratio alone — and you can calculate it from labs you probably already have.
This is why cardiovascular risk assessment at Beacon goes beyond a standard lipid panel — ApoB, Lp(a), insulin resistance markers, hs-crp, and imaging like a CAC score when the picture is unclear. Not a slogan. Your actual risk.
When “lower LDL is always better” becomes dogma, even asking questions can look radical. Here’s what one cholesterol controversy reveals about evidence, medicine, and scientific humility.
