The Claim

Among patients with coronary artery disease and high lipid plaque density index (LPDI ≥7.65), achieving an LDL cholesterol level below 55 mg/dL is associated with a reduced incidence of major adverse cardiovascular events, including cardiac death, non-fatal myocardial infarction, and unplanned revascularization.

In plain English

In patients with coronary artery disease and high plaque density, having LDL cholesterol below 55 mg/dL is linked to fewer heart attacks, cardiac deaths, and need for repeat heart procedures.

See the scientific wording

Among patients with coronary artery disease and high lipid plaque density index (LPDI ≥7.65), achieving an LDL cholesterol level below 55 mg/dL is associated with a reduced incidence of major adverse cardiovascular events, including cardiac death, non-fatal myocardial infarction, and unplanned revascularization, suggesting that plaque phenotype may influence response to intensive lipid-lowering therapy.

Why this might work

When LDL cholesterol drops below 55 mg/dL, fat builds up less in artery walls and existing fatty deposits shrink as immune cells remove the excess fat. This makes the plaques tougher and less likely to burst, which stops blood clots from forming and prevents heart attacks or the need for emergency artery procedures.

  1. Study: Lipid plaque density index as a phenotypic plaque feature which benefits from achieving LDL-C <55 mg/dL: Observations from the REASSURE-NIRS Multi-center Registry

    In people with heart disease and fatty plaques in their arteries, lowering LDL cholesterol below 55 mg/dL helped prevent heart attacks and other serious problems—but only if their plaques were very fatty. If their plaques weren’t fatty, lowering LDL didn’t help as much.
