Surprising Findings
An 88% reduction in heart disease risk in Black carriers of a PCSK9 nonsense mutation
Such a large protective effect was unexpected, especially in a population often considered high-risk for heart disease due to social and health disparities.
Practical Takeaways
Prioritize long-term cholesterol management — starting early may offer far more protection than waiting until middle age.

People with certain genetic changes that turn down a protein called PCSK9 tend to have lower 'bad' cholesterol their whole lives and are much less likely to get heart disease.
People who naturally have lower 'bad' cholesterol because of their genes tend to have cleaner arteries, which means less buildup of plaque over time.
Black adults with a certain genetic mutation have much lower bad cholesterol and are way less likely to get heart disease over 15 years — this shows that keeping cholesterol low from an early age could really protect your heart, even if you're at higher risk.
White adults with a certain gene variant have lower bad cholesterol and are nearly half as likely to get heart disease over 15 years — showing that even a small, lifelong drop in cholesterol can really protect your heart.
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.
