'Good' cholesterol doctrine may be flawed, says study

(PARIS-AFP) - Researchers on Thursday challenged a tenet of modern medicine that higher levels of "good" cholesterol automatically boost cardiovascular health.

In a study published in The Lancet, investigators said they found no evidence to back the belief that higher levels of high-density lipoprotein (HDL) cholesterol routinely reduce the risk of a heart attack.
High concentrations of HDL are one of the big markers for blood tests.
