The Study
LDL treatment-years: a new paradigm for cardiovascular risk reduction
This study looked at lots of past heart trials and found that people who lowered their bad cholesterol for longer tended to have fewer heart problems. But it didn't do new experiments—it just added up results from other studies, so we can't say for sure that lowering cholesterol caused the improvement.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
Lowering cholesterol isn't just about how low it goes—it's also about how long you keep it low. This study found that if you lower cholesterol enough and keep it down for long enough, you prevent more heart attacks.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes—this means starting strong and fast after a heart attack (e.g., with PCSK9 inhibitors) may save more lives than slowly increasing statins over time.
- 2A total of 79.5 LDL treatment-years (e.g., lowering LDL by 50 mg/dL for 1.6 years, or 100 mg/dL for 0.8 years) was needed to reduce heart attacks.
- 3Trials above 135.6 LDL treatment-years saw big benefits; those below 57.8 saw none.

Starting high-intensity LDL-lowering treatment with PCSK9 inhibitors immediately after a heart attack leads to fewer major heart events compared to slowly increasing statin doses, because it lowers LDL cholesterol to a cumulative target of 79.5 LDL treatment-years faster.
People treated with LDL-lowering therapies for longer durations and at higher cumulative levels have fewer heart attacks and strokes compared to those with lower cumulative exposure.
Using a fixed LDL cholesterol target below 55 mg/dL does not reflect how long a person has been lowering their cholesterol, and this approach may not properly guide treatment for people at high risk of heart disease.
People who have had lower LDL cholesterol levels for longer periods have a lower rate of serious heart problems, such as heart attacks and strokes, compared to those with less cumulative exposure.
Longer and more intense LDL-lowering treatment is required to reduce cardiovascular events, and trials that failed to show benefit did so because the treatment was not given long enough or strongly enough.
