People born with a certain gene that lowers their bad cholesterol their whole life have a lower risk of heart disease than what we'd expect from cholesterol-lowering drugs like statins — meaning starting early and keeping cholesterol low for longer might protect the heart better.
See the scientific wording
Lifelong reduction in LDL cholesterol due to genetic variants in the PCSK9 gene is associated with a greater reduction in coronary heart disease risk than that predicted by clinical trials of statin therapy, suggesting that earlier and sustained LDL cholesterol lowering provides enhanced cardiovascular protection.
Correlational — new studies may shift this
ObservationalOne moderate-quality study links this claim to the outcome, but causation is not established.
What the research says

Sequence variations in PCSK9, low LDL, and protection against coronary heart disease.
Cohort StudyHuman2006
People born with certain PCSK9 gene changes have lower cholesterol their whole lives and are much less likely to get heart disease, even more than expected from cholesterol-lowering drugs, suggesting early and long-term lowering helps more.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Mendelian Randomization Studies on PCSK9 Variants and Coronary Heart Disease Risk vs. Statin Trial Outcomes
Systematic review and meta-analysis of Mendelian randomization studies comparing the effect size of PCSK9-related lifelong LDL reduction on coronary heart disease risk versus pooled effect sizes from statin RCTs, adjusting for LDL reduction magnitude.
Long-Term PCSK9 Inhibitor Initiation in Young Adults vs. Standard Statin Therapy for Primary Prevention
Double-blind, randomized controlled trial comparing early-life initiation of PCSK9 inhibitors versus standard statin therapy in middle age, tracking coronary heart disease incidence over 20+ years in high-genetic-risk individuals.
Longitudinal Cohort Study of PCSK9 Variant Carriers vs. Non-Carriers with Matched LDL Levels on Statins
Prospective cohort study following PCSK9 loss-of-function variant carriers and matched controls on statins with similar LDL levels, comparing incident coronary heart disease over decades.
Case-Control Study of PCSK9 Variant Frequency in Early-Onset CHD Patients vs. Protected Elderly Controls
Case-control study comparing the prevalence of PCSK9 variants in individuals with early-onset coronary heart disease versus age-matched controls with lifelong low LDL and no disease.
Cross-Sectional Analysis of Coronary Artery Calcium Scores in PCSK9 Variant Carriers vs. Statin-Treated Individuals with Similar LDL Levels
Cross-sectional study measuring coronary artery calcium scores in asymptomatic adults with PCSK9 variants versus those on statins with matched LDL levels.
