Study questions effect of ‘good’ cholesterol on cardiac health
Little effect found on heart disease
Raising levels of “good’’ cholesterol may not be so good for you after all. A study published Wednesday by Boston-area scientists challenges the long-held idea that HDL cholesterol actively protects against heart disease, finding that people with genes that boosted their HDL did not have a lowered risk of heart attacks. The study appearing in the medical journal The Lancet examined the health of more than 100,000 people, some of them with genetic variations that elevated their levels of HDL.
