The Claim

In patients with established atherosclerotic cardiovascular disease, lowering LDL cholesterol to below 55 mg/dL reduces the risk of major adverse cardiovascular events by 33% over 3 years, with no increase in adverse events compared to higher LDL cholesterol targets.

Cause and effect
1 study reviewed
In plain English

For people with known heart disease, lowering LDL cholesterol to under 55 mg/dL reduces the chance of heart attacks, strokes, or death by 33% within three years, and does not increase the rate of side effects compared to higher LDL targets.

See the scientific wording

In patients with established atherosclerotic cardiovascular disease, lowering LDL cholesterol to below 55 mg/dL reduces the risk of major adverse cardiovascular events by 33% over 3 years, and this benefit is achieved without increasing safety risks, as demonstrated by comparable adverse event rates to higher LDL targets.

Why this might work

When LDL cholesterol drops below 55 mg/dL, less cholesterol enters the artery walls, causing fatty plaques to shrink and become less inflamed. This makes the plaques tougher and less likely to burst, which prevents blood clots that cause heart attacks and strokes.

What the research says

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

    For heart disease patients with fatty, unstable plaques in their arteries, lowering LDL cholesterol below 55 mg/dL greatly reduces the chance of heart attacks or strokes. But this benefit doesn’t seem to happen for everyone — only those with these specific dangerous plaques.
