The Claim
The reduction in coronary heart disease risk associated with PCSK9 gene variants is proportional to the extent of LDL cholesterol lowering, with a 88% lower risk observed for approximately 28% reduction in LDL cholesterol and a 47% lower risk for approximately 15% reduction, indicating a graded relationship between lifelong lower LDL cholesterol levels due to genetic variation and reduced incidence of coronary heart disease.
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.
People born with certain gene changes that lower their bad cholesterol over their whole life have a lower chance of heart disease — the more their cholesterol is lowered, the lower their risk.
See the scientific wording
The degree of coronary heart disease risk reduction associated with PCSK9 variants is proportional to the magnitude of LDL cholesterol lowering, with 88 percent lower risk for ~28 percent LDL reduction and 47 percent lower risk for ~15 percent LDL reduction, suggesting a graded relationship between lifelong LDL exposure and CHD incidence.
What the research says
1 studyStudy: Sequence variations in PCSK9, low LDL, and protection against coronary heart disease.
The study looked at people born with genetic changes in the PCSK9 gene that lower their bad cholesterol their whole life, and found the more their cholesterol was lowered, the lower their risk of heart disease — just like the claim says.
