The Claim

Genetically reduced PCSK9 function is associated with a 24% lower risk of abdominal aortic aneurysm (AAA) in a trans-ethnic population of 312,097 individuals, with an odds ratio of 0.76 (95% CI: 0.68–0.86, p = 2.9 × 10⁻⁶), suggesting that lifelong lower LDL cholesterol due to inherited PCSK9 variation may confer protection against AAA.

In plain English

People born with a certain genetic quirk that lowers their bad cholesterol over their whole life seem to have a lower chance of developing a dangerous belly blood vessel problem called an abdominal aortic aneurysm.

  1. Study: PCSK9 loss of function is protective against extra-coronary atherosclerotic cardiovascular disease in a large multi-ethnic cohort

    The study looked at people with natural changes in the PCSK9 gene that lower bad cholesterol, and found they had a 24% lower risk of a dangerous belly artery problem, just like the claim says.
