The Claim
In patients with established atherosclerotic cardiovascular disease, targeting an LDL cholesterol level below 55 mg/dL reduces the risk of major cardiovascular events by 33% over 3 years compared to targeting below 70 mg/dL, with cumulative event rates of 6.6% and 9.7%, respectively, without increasing overall safety risks, supporting lower LDL targets for secondary prevention.
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.
For people who already have heart disease, aiming to get their 'bad' cholesterol (LDL) below 55 mg/dL cuts their risk of serious heart problems by about one-third over three years compared to aiming for below 70 mg/dL — and it doesn’t seem to cause more side effects.
See the scientific wording
Targeting an LDL cholesterol level below 55 mg/dL reduces the risk of major cardiovascular events by 33% over 3 years compared to targeting below 70 mg/dL in patients with established atherosclerotic cardiovascular disease, with a cumulative event rate of 6.6% versus 9.7%, respectively. This benefit occurs without increasing overall safety risks, supporting lower LDL targets for secondary prevention.
What the research says
1 studyStudy: Intensive LDL Cholesterol Targeting in Atherosclerotic Cardiovascular Disease
The study found that aiming for very low LDL cholesterol (below 55 mg/dL) cut heart risks by about one-third compared to a less strict target, just like the claim says, and it was safe.
