The Claim
In patients with atherosclerotic cardiovascular disease, lowering LDL cholesterol to a median of 56 mg/dL, compared to 66 mg/dL, reduces the hazard of a composite cardiovascular outcome by 33% (hazard ratio 0.67) over a 3-year period, with an absolute risk reduction of 3.1 percentage points and a number needed to treat of 32 to prevent one major cardiovascular event.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you have heart disease from clogged arteries, getting your bad cholesterol down to around 56 mg/dL instead of 66 mg/dL can cut your risk of heart attacks or strokes by about a third over three years. For every 32 people treated this way, one person avoids a major heart problem.
See the scientific wording
Among patients with atherosclerotic cardiovascular disease, lowering LDL cholesterol to a median of 56 mg/dL reduces the hazard of a composite cardiovascular outcome by 33% (HR 0.67) over 3 years compared to 66 mg/dL, with absolute risk reduction of 3.1 percentage points, translating to a number needed to treat of 32 to prevent one major cardiovascular event.
What the research says
1 studyStudy: Intensive LDL Cholesterol Targeting in Atherosclerotic Cardiovascular Disease
The study looked at patients with heart disease and found that lowering their bad cholesterol more deeply reduced their risk of heart problems by about one-third over three years, just like the claim says.
