HDL has been thought to lower cardiovascular risk by cleansing the bloodstream of “bad” cholesterol and scrubbing the inner walls of blood vessels, so your levels of HDL were thought to predict your risk of heart attack or stroke. But this new data suggests HDL may just be a fatty substance along for the ride.

And HDL may yet redeem itself in the world of drug development…It’s possible a deeper look at HDL subtypes could reveal a more nuanced relationship with cardiovascular disease….
