The Claim
Among patients with atherosclerotic cardiovascular disease on statin therapy, achieving less than a 50% reduction in LDL-C is associated with a 107% higher risk of stroke compared to achieving a 50% or greater reduction, regardless of whether both groups reach LDL-C levels below 70 mg/dL.
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.
In patients with atherosclerotic cardiovascular disease taking statins, those whose LDL cholesterol decreases by less than 50% have a 107% higher risk of stroke than those whose LDL cholesterol decreases by 50% or more, even when both groups end up with LDL cholesterol below 70 mg/dL.
See the scientific wording
Among patients with atherosclerotic cardiovascular disease on statin therapy, those achieving less than a 50% reduction in LDL-C have a 107% higher risk of stroke compared to those achieving 50% or greater reduction, even when both groups reach LDL-C levels below 70 mg/dL, indicating that the magnitude of LDL-C reduction may be particularly important for stroke prevention.
When LDL cholesterol drops by more than half, plaque in the arteries becomes more stable and less likely to rupture, and inflammation in the blood vessel walls decreases, which prevents clots from forming and blocking brain arteries.
What the research says
1 studyEven if two heart disease patients end up with the same low cholesterol level, the one whose cholesterol dropped by at least half has a much lower risk of stroke than the one whose cholesterol dropped less. The bigger the drop, the better the protection — no matter how low the final number is.
