The Claim

In patients with coronary artery disease and multiple non-culprit lesions exhibiting lipid-rich plaque (maxLCBI4mm ≥324.7), achieving LDL-C below 55 mg/dL is associated with a 78% lower risk of major adverse cardiac events (adjusted HR = 0.22, 95% CI: 0.09–0.53), whereas no significant benefit is observed in those with only a single such lesion.

In plain English

Among patients with coronary artery disease and multiple lipid-rich plaque deposits, those who reduce their LDL cholesterol to below 55 mg/dL have a 78% lower rate of major adverse cardiac events compared to those who do not, but patients with only one such plaque deposit do not show this benefit.

See the scientific wording

In patients with coronary artery disease and multiple non-culprit lesions exhibiting lipid-rich plaque (maxLCBI4mm ≥324.7), achieving LDL-C below 55 mg/dL is associated with a 78% lower risk of major adverse cardiac events (adjusted HR = 0.22, 95% CI: 0.09–0.53), whereas no significant benefit is observed in those with only a single such lesion.

Why this might work

When bad cholesterol is lowered below 55 mg/dL, it stops more fat from entering unstable fatty plaques in the artery walls. This causes existing fat inside the plaques to shrink and reduces swelling from immune cells. The plaque's outer covering thickens and becomes tougher, making it less likely to burst and trigger a blood clot that blocks the artery.

    For people with multiple fatty buildups in their heart arteries, getting their bad cholesterol below 55 mg/dL greatly lowers their risk of heart attacks or other serious heart problems. But if they only have one such fatty buildup, lowering cholesterol doesn’t seem to help as much.
