Does a blood-fat insulin score predict early heart disease?
The claim, precisely: lipoprotein insulin resistance correlates with cardiovascular disease
Yes — it beat bad cholesterol in one large study, but it shows association, not proven cause.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Population patterns (Observational)
How the studies fall
What the evidence shows
A lipoprotein-insulin-resistance (LPIR) score discriminated premature coronary heart disease better than LDL-C in a large women's cohort - real support for the 'metabolic context matters more than LDL alone' framing, though single-cohort and observational.

| Dugani SB, et al. 2021 · JAMA Cardiol | observational | supports | moderate | JAMA Cardiol (n~28,000 women): LPIR & metabolic markers best distinguished premature CHD; LDL-C a weak discriminator |
