The Claim

In patients with coronary artery disease and lipid-rich plaque (maxLCBI4mm ≥324.7), achieving LDL-C below 55 mg/dL is associated with a significantly lower frequency of major adverse cardiovascular events (MACE), with an adjusted hazard ratio of 0.27 (95% CI: 0.08–0.97).

In plain English

In patients with coronary artery disease and fatty plaques in their arteries, lowering LDL cholesterol below 55 mg/dL is associated with fewer heart attacks, strokes, or deaths from heart disease compared to higher LDL levels.

See the scientific wording

In patients with coronary artery disease, achieving LDL-C below 55 mg/dL is associated with a significantly lower frequency of MACE in lesions with lipid-rich plaque (maxLCBI4mm ≥324.7), with an adjusted hazard ratio of 0.27 (95% CI: 0.08–0.97), supporting the hypothesis that lipid-rich plaques are more responsive to intensive lipid-lowering therapy.

Why this might work

When bad cholesterol is lowered below 55 mg/dL, it stops more fat from entering fatty plaques in the artery walls and removes existing fat from inside them. This reduces swelling and immune cell buildup in the plaque, making the protective cap over the plaque thicker and the dangerous core smaller. As a result, the plaque becomes less likely to burst and trigger a blood clot that causes a heart attack or stroke.

  1. Study: Achieved LDL-C levels <55 mg/dL and cardiac events in patients and lesions harbouring lipid-rich plaque phenotypes

    In people with fatty buildups in their heart arteries, lowering bad cholesterol below 55 mg/dL helped prevent heart attacks and other serious events — but only in those with the fattest plaques. Other plaques didn’t benefit as much.
