Some cholesterol-lowering drugs called PCSK9 inhibitors can lower a specific type of blood fat linked to heart disease, and that might help protect people with high levels, but scientists aren't sure exactly how it works yet.

Some cholesterol drugs called PCSK9 inhibitors also lower another harmful fat in the blood called lipoprotein(a), and that might help protect the heart in ways that aren't just about lowering bad cholesterol.

These cholesterol drugs, called PCSK9 inhibitors, probably help lower bad cholesterol in many types of patients — more than fake pills or other cholesterol medicines.

These cholesterol drugs work well for lots of different people, even if they're already taking other meds for high cholesterol.

People born with a certain gene change that breaks the PCSK9 gene tend to have much lower 'bad' cholesterol their whole lives and are far less likely to get heart disease — so scientists think blocking this gene with medicine might help protect others' hearts too.

PCSK9 inhibitors can help lower bad cholesterol, either when added to other treatments or used instead of them.
